Today is my last day off. Not quite a day off either, more of a day to get ready. While classes haven’t officially started for me, it’s time to get some work done. So in the spirit of chronicling my life as a PhD candidate, I figure today we can take a look at my todo list and you’ll see why today isn’t a day off. Hint, there’s a lot of prep going into this next week.(more…)
Yes, once again I am trying to force myself to do nothing useful. Or rather to do useful things for myself instead of for others. My mental health has run ragged since the pandemic hit and it only got worse as the year progressed. Since winter time is particularly difficult for me to deal, I plan on some decompression time. I’ve talked about it before, but what’s the point of blogging daily if I can’t talk about it again?(more…)
It’s a new year, a new chapter, and it’s time to set some new goals. What kinds of craziness will I accomplish this year? Well I have a few ideas. No pressure or anything, I don’t want to force myself to fit things into the year just because I planned for it. Instead I like to set goals so I can check things off a list (I do love my lists). So even if that list rolls into the next year, it’s not the end of the world. Just a helpful hint for those of us who are chronically anxious!(more…)
Today was the last experiment that I’ll be doing for the next couple of weeks and since classes are over it’s time to kick my feet up and relax. Okay, not really. There are still some odds and ends that I will probably be working on while I’m “taking a break,” but overall I’m excited to not have things I NEED to do. I’ll probably be doing some house stuff too, but hey at least its a change.(more…)
The meeting with my PI is done and it’s not all bad news. It went better than expected in some aspects and not so great in others. That’s how these things work out, it’s not a linear progression, it’s a lot of going back and forth and sometimes side to side too. Thankfully we met before I made any firm plans! Anywho, let’s just dive in and talk about what happened.(more…)
My deadline is fast approaching and I still have a lot of work to do. I’m also struggling with feeling super unmotivated. Normally when this hits I take a day or two to relax and then I’m ready to go. Unfortunately with my deadline approaching I need to use a different technique to get through what I need without driving myself crazy(er).(more…)
I had one of those shower realizations last night. I was thinking about all the writing I’ve done and how much I still have left and suddenly it occurred to me that I was done with all the writing… for now. That’s not the only thing though, I had the realization that I wrote more the second two weeks than I had the first two, by a lot.(more…)
Every sunday without fail I make my list of tasks for the week ahead. Some of them are automated and repeat as needed, but most are specific to that week so I need to go in manually and add them. It’s nice to have everything written down in one place, in order, with times and reminders. I don’t have to stress out about remembering everything when I have a nice app on my phone that keeps me informed. Unfortunately there is a downside…(more…)
Some days there’s just so much going on it’s hard to figure out what to write about. Daily writing is hard because some days you have 50 things you want to share and some days you can’t figure out a single thing that would be interesting to write about. While I have a million things to do, none of them are new and interesting enough to share. So today I’ll let you in on my secret.(more…)
With classes about to kick off I’m left wondering what will be different for me. This term I’m doing the safe thing and taking a single online course. The rest of my time will be focused on my research and doing what I need to do to be ready for my PhD proposal defense (the step I want to take this fall term. So what am I doing to get ready?(more…)
We’re looking forward today… while looking back too. I did a big thing! I finished my 365 days of academia goal, it felt too big to do, but here we are. So what’s next? Well we’re going to talk about where we are, where we were, and what’s coming, so let’s get to it!(more…)
Well here’s something I never thought I would have to write about, the food is all right. Contrary to reports by police, no one is poisoning their food. In fact, every time a new story comes up regarding tapered food and the police it turns out the officers involved were (surprise!) lying outright. There are strangely so many of these incidents that it’s hard to keep up with, what is it about police that makes them think it’s okay to keep lying?
Well as if we didn’t already have an overabundance of apocalyptic events occurring all at the same time, now we have trump rolling back protections for the LGBTQ+ community while the supreme court ruled in favor of protections for LGBTQ+ people. It’s all very confusing, but while we’re trying to burn down the system, need to build in protections for the LGBTQ+ community too.
Rayshard Brooks was murdered by police. Murdered isn’t quite a strong enough word for what the police did, but we’ll go with it. He was murdered. I don’t know the man, but I can tell you he had three daughters and a step son. I can also tell you he was murdered for being responsible. He was murdered for celebrating his daughters 8th birthday. He was murdered for doing the right thing. But today we mourn the wendy’s that was burned down.
The protests are still going strong and that makes my heart happy. You knew the protests were still going on though… right? I don’t blame you if you thought they had died down, turns out when protesters aren’t burning down buildings the media doesn’t seem to care, even when police decide to use excessive force and LITERALLY run people over.
Welcome to solid modeling for beginners! Each week I’ll post some new and exciting things so you can try your hand at solid modeling. It’s easier than it looks to get started and once you do, you’ll be able to create amazing things that you can 3D print, plans to build something really cool, or maybe you just want to create some art! You can do anything you want with solid modeling, that’s the beauty of it! Let’s get started.
Well today I was planning on posting a quick tutorial for everyone who wanted to learn solid modeling. Have no fear! We’re still going to do it, but that will have to wait to tomorrow. I’ve got a lot going on at the moment and creating a good tutorial from scratch will take a bit of time. What am I doing now? Well, I’m glad you asked.
A friend once described me as, “a maker if there ever was one.” If you ask me, he was being overly kind, but it’s true I enjoy making things. I’m always looking to learn new skills or sharpen old ones. In fact, I’m taking up some “light” woodworking over the summer to do some custom pieces for my home. It will be a fun task, if not a bit tedious and time consuming. I have a list of projects you see, but not a lot of time to do them.
One of the many hats I wear as a PhD candidate is my mentor hat. It’s probably one of my favorite jobs and I get to work with some truly brilliant people from all types of backgrounds. I’ve had the chance to mentor a small handful of people and I always look forward to learning from them and through our interactions, in that sense, it’s a mutually beneficial relationship.
…and thus our mighty hero slay the beast and rode off into the sunset to live happily ever after. But why? Have you ever really thought about the way some stories choose their endings? Our hero goes through live altering and extremely daunting challenges only to brush it off like he caught the wrong bus. Pardon me, but what the actual fuck?
I just want to sleep for fifty years, is that so much to ask for? The deadline is gone whence it came! That does not mean it wasn’t a fight to the end or that there is a weird stillness permeating the house like a calm after a storm. What is it about things ending so abruptly that throws a person into a spiral of confusion?
Well I got word yesterday that the coronavirus found its way onto an aircraft carrier. For anyone who’s never seen one in person, because the pictures don’t do it justice, these things are huge. Think floating cities with the crew size to match. Inside an aircraft carrier, there are roughly 3,000+ people who work, live, and maintain the ship. The one in question, the U.S.S. Theodore Roosevelt has over 4,000 crew members and those are just the ones that need to be quarantined. This is bad for a lot of reasons. For those of you who haven’t served in the military, I’ll explain.
For the past week we have been utilizing online resources so that classes can continue while we are all social distancing. While this is means that we mostly use Zoom, we also have message boards and other resources that we can use. However, these resources are sometimes a poor substitute for in person classes. This is especially apparent when we have certain assignments for the class, such as a group presentation.
Well it’s been two weeks since the last critical review so it’s that time again. As usual, my PI gets a copy and so do all of you. Since I’ve done several of these now (this is number six) I have a category just for these reviews called critical reviews. This is a really new study which tries to help tease apart what we are actually stimulating when we apply transcutaneous spinal stimulation. I think it’s a super interesting paper and I hope you do as well.
I hate writing about the VA, I really do. Unfortunately because I live here in the US where we think it’s our right to die from disease and have ludicrous amounts of medical debt for a sprained ankle, it’s a conversation we should have. Hello America, I served my country and now my country wants me dead. I sincerely wish I was exaggerating. Please hold your, “thank you for your service” for the end that way I can tell you to go fuck yourself. Let me explain…
Fun fact, I love pandemic movies. Movies, not so much living through one. As humans we are selfish, greedy, prone to panic, and for being “evolved” we are so very, very stupid. Basically every dumb choice you see the characters in those movies make while screaming, “you idiot, that would never happen in real life!” Well, it’s happening and wow does it do a number on a persons mental health. But hey guess what? I’m essential, so let’s figure out what that means in a time where the world is practically on fire.
Well if you missed it, yesterday was our final post in the know your spinal cord series. I’m not crying, you’re crying! Now the question is, what does that mean for the blog? An excellent question, one I wish I would’ve asked myself! Let’s take a look at some of the things that we will (probably) be discussing now that our designated topic has run its course.
It’s day fifty-four and we’ve hit the end of our journey for this mini-series. For one last time, you can find all our posts in the neuroanatomy category. Everything comes to an end eventually and today I think we should do a small wrap up. This isn’t just a repeat of everything we went over though, we’re going to attempt to tie a lot of the topics together. So let’s give this a shot.
Here we are on day fifty-three, we are nearing the end for sure. I was going to end the series today, but there is at least one more thing that I think will be interesting to cover. As always, you can find all of our posts in the neuroanatomy category, after all there are quite a few now. Today we are going to talk about how the brain and muscles use different signals to communicate. Basically, they speak different languages; let’s talk about what that means.
It was bound to happen, with the COVID-19 outbreak, my entire schedule has been shifting faster than I can keep up with it. I was going to force myself to write today, but I need a break. I’m exhausted both mentally and physically. There is a possibility I won’t be getting my stipend from the school this month, even though I’m still working, and I have assignments due soon, so I can’t dedicate the normal hour or so I would writing.
Friendly reminder, wash your hands, don’t touch your face, and practice social distancing. Even if you’re healthy, you can infect people that are not healthy or worse, people who work with others who are not healthy. Don’t be selfish! It may seem stupid now, but if we don’t do these things then it will get a lot worse and no one wants that. We can get through this if we all work together.
Well after our short break yesterday with my biweekly review paper, it’s back to the know your spinal cord series and we’re on day fifty-two! If you’re here for the first time, you can find the posts in this mini-series in the neuroanatomy category. We’ve taken a few twists and turns since we’ve started the series, but we’ve covered way more than I originally planned. We’ve covered how transcutaneous spinal cord stimulation is thought to work, that post focused on the type of spinal cord stimulation I’m researching. However, there are other ways to stimulate the cord. Transcutaneous spinal direct current stimulation (tsDCS) is a different way to stimulate and today we will talk about the difference.
Day 210: Review – Cervical trans-spinal direct current stimulation: a modelling-experimental approach
I lied! I did know what today was going to be on, it’s the fifth critical review paper. Since my PI gets a copy, so do you! To be honest, I need to create a category for these reviews (Update: I did make a category, Critical reviews), but for now, my first looking at elbow spinal stretch reflexes is here. My second where I review modulating spinal cord excitability with a static magnetic field here. The third where I review modulating the H-reflex while walking in spinal cord injury populations. Lastly, my fourth on Motoneuron excitability during voluntary muscle activity in a spinal cord injury population can be found here. That said, let’s take a look at my latest review.
It’s day fifty-one of knowing your spinal cord! For those of you who just found us, fear not we have all these posts in reverse chronological order listed in our neuroanatomy category. For everyone else, lately we’ve been talking about glial cells. This came about from the post on glial scarring which made me realize we should probably define glia. There are four types of glial cells found in the spinal cord (that we know of) we’ve covered three of them already and today we are talking about the last kind, the microglia.
We made it to yet another milestone, day fifty in our know your spinal cord series! As usual, you can find each and every one of these posts neatly organized in reverse chronological order using our neuroanatomy category. For the past couple of posts, we’ve introduced the types of glial cells, probably a bit poorly, but they are just so complex we can only really focus on a few of the functions. Needless to say they are very important cells. Today we are talking about the third (of four) types of glial cells found in the spinal cord (and brain), that is the ependymocyte. Let’s take a look.
Day forty-nine in the spinal cord series! You can find all the posts in this series in our super useful neuroanatomy category. A couple of posts back we introduced glial scarring, one of the problems we need to overcome to help people with spinal cord injuries. That led to the realization that we needed to introduce the glial cells, so yesterday we covered the oligodendrocytes and today we are talking about the astrocyte. Now that we have some background of how we got here, let’s introduce today’s topic.
We made it to day forty-eight! As always, the neuroanatomy category will help you find each and every post in the spinal cord series. It’s all really good stuff! We mentioned yesterday that this was coming, we’re going to do a quick breakdown of the types of glial cells just to make understanding the glial scarring post easier. Plus it helps to understand the functions of glial cells in general when we talk about things that could go wrong. With that, let’s get into oligodendrocytes!
Here we are at day forty-seven of spinal cord posts. We are definitely wrapping up our series sad to say, maybe we can get to day fifty, that would be a nice round number to stop at. For those of you who want to read all the other posts, the neuroanatomy category has everything in reverse chronological order and will teach you everything from the medullary pyramids, the cauda equina, and all the stuff in between. Today we are talking about glial scarring and why it’s such a problem a topic I realized we should touch on after talking about the problems with invasive spinal stimulation methods yesterday.
It’s day forty-six in our spinal cord series. While we’re nearing the end (maybe), there are still a few things to cover. First, if you’re new, you can find all of the posts in the neuroanatomy category for when you need a quick spinal cord fix. I’ve been debating about this post for some time, but I figure we might as well cover it since we’re here. Today we are going to talk briefly about invasive spinal stimulation and what the future might hold.
Day forty-five of the know your spinal cord series is here! With so many posts, you may be wondering how to find them all. Fear not, we have a super helpful neuroanatomy category for all your spinal cord needs. For the past few posts we’ve looked at some very interesting tools to probe the spinal cord. We’ve seen that there are quite a few ways we can go about it, but more importantly they all tell us something slightly different. Today we are looking at the product of that stimulation, the compound action potential.
Welcome to day forty-four in the know your spinal cord series! As usual all of our posts are in a super easy to find neuroanatomy category. Now that we’ve covered our into into diagnostic tools to probe the spinal cord, let’s look at some of the ways we are working to help treat spinal cord injuries. Today we’re looking at a heavy hitter so to speak and something my research is focused on, transcutaneous spinal stimulation (TSS). Let’s take a look!
We’ve made it to day forty-three of our know your spinal cord series! While that is a lot of posts, we’ve made it super simple for you to find all of them with our neuroanatomy category. Lately, we’ve looked at several different tools in our spinal cord probing toolbox. We’ve seen all sorts of different ways to create a response, but we are still missing one important tool for our exploration into the unknown spinal cord world and that is what we are going to talk about today!
We’re back again with day forty-two of spinal cord knowledge series and day 200 in our 365 days of academia series! A friendly reminder that you can find each and every one of these posts in our very helpful neuroanatomy category. Yesterday we looked at motor evoked potentials, or electrical pulses that we create which travel from the brain to the muscles. Today we are looking at the almost reverse, signals we create originating in the peripheral nerves and arriving at the somatosensory cortex of the brain.
Day forty-one in the know your spinal cord series. While the number of posts is going up, we made them easy to find by using our awesome neuroanatomy category! Maybe we did this a bit backwards, but it’s our series and this was the order we did it in. Yesterday we covered cervicomedullary motor evoked potentials, which is a subset of what we will be covering today. So again, slightly out of order, but hey let’s look at motor evoked potentials.
We made it, day forty in the know your spinal cord series! I honestly didn’t think we would get this far into things, but here we are. As per usual, if you’re new you can find all of the posts in this series in our super helpful neuroanatomy category! For the rest of you, or the ones interested in this topic, today we are looking at yet another tool in uncovering the secrets of the spinal cord.
It’s day thirty-nine of our know your spinal cord series and we’re only touching the surface (so to speak)! If you’re just joining us, then welcome! You can find all of our spinal cord knowledge in the handy neuroanatomy category. Well as these things typically happen, yesterday brought up an interesting gap in our knowledge base. While I introduced the H-reflex, we never talked about the F-wave! So of course yesterday’s post probably left some of you scratching your head as to what an F-wave even is, fear not we’re going to clear that up today!
Day 196: Review – Changes in Motoneuron Excitability during Voluntary Muscle Activity in Humans with Spinal Cord Injury
A little detour from our spinal cord series for my fourth critical review paper. As usual, my PI get a copy and so do all of you! You can read my first looking at elbow spinal stretch reflexes here. My second where I review modulating spinal cord excitability with a static magnetic field here. Or the third where I review modulating the H-reflex while walking in spinal cord injury populations. Today is an interesting paper on motoneuron excitability while walking in spinal cord injury populations. It’s a really cool paper, so here’s my review.
Welcome to day thirty-eight in the know your spinal cord series. As always, you can find the entire know your spinal cord series exclusively listed under our neuroanatomy category. We’ve amassed quite a bit of spinal information and I’ve gotten into more detail than I originally planned, which is part of the reason why we are going back and covering some of the things we skipped over. Today is one of those topics, we will be talking about the spinotectal tract, not to be confused with the tectospinal tract, which we already covered.
We’ve arrived at day thirty-seven in the spinal cord series and we’re still covering new ground. You can find all of our sweet spinal cord action in the neuroanatomy category, which at this point is pretty extensive for a high-level look. Yesterday we talked about the reticulospinal tracts so today we are talking about the sister tract, the spinoreticular tract. Are they related, or is it all just in the name?
It’s day thirty-six in our spinal cord series and I yesterday I lied, we’re not done quite yet. First, as always we have a super helpful neuroanatomy category for anyone wanting to read the posts from this series. For the rest of us, today we’re talking about the reticulospinal tracts, yes tracts with an s. There is a good reason for this, but you’ll have to read on to see why. (more…)
Welcome to day thirty-five in the know your spinal cord series! For the new people, we have a whole neuroanatomy category dedicated to these posts! For everyone else (or those of you just interested in today’s topic, this is going to be on another smaller tract of the spinal cord we haven’t covered yet. Today we are talking about the tectospinal tract, not to be confused with the spinotectal tract, so let’s get started.
