Well today is a full day since I had the second dose of my COVID vaccine. I promised honesty and transparency so here it is, the second dose isn’t as smooth as the first. So we’re going to go over why that is, what my issues have been, and why it’s still very much worth it.(more…)
It’s my favorite post of the year!!! Every year I update and post my favorite Halloween tradition! That’s right today we bring you the science fact behind the undead. Zombies, those brain loving little things are everywhere. Sure, we are all familiar with the classic zombie, but did you know that we aren’t the only zombie lovers out there? It turns out that nature has its own special types of zombies, but this isn’t a science fiction movie, this is science fact! Sometimes fact can be scarier than fiction. Let’s talk zombies.(more…)
Well that was a …flop. Today I had an experiment, had. There are a lot of moving parts when it comes to an experiment, especially in my line of research. Technology, can’t live with it, can’t live without it. Still, somedays I wish I was living in the future, one where I didn’t need to reset my router randomly. Then I would know for sure the singularity was close.(more…)
I did an experiment! That’s old(ish) news, but now I have some data to play with… lots of data. So now I get to do something somewhat enjoyable and that’s try to get cool and interesting stuff to fall out of it. All you have to do is shake it really hard and hope for the best.(more…)
Well… where the hell do I even start? Yesterday was actually a semi-okay day. I mean the world is still on fire, the pandemic is still killing far too many people( but somehow not enough for the people in charge to care), and I mean let’s face it, it feels like the human race is in the death throes. HOWEVER, all that aside, my microscopic insignificant day wasn’t bad… now I’m worried.(more…)
A new turn in the saga of my data processing. There has been some concern that the artifact from the stimulation is causing the thing I am seeing in my data. There are arguments to be made for both sides, but let’s go over what that could mean for me.(more…)
Well I’ve processed (poorly) about half of my data. Now, when I say poorly I just mean the visuals for it are garbage and I need to tweek the sizes and things to make it look nicer, but the idea is that I’m more interested in finding something than I am in making it look pretty. I’ve processed two of four of my subjects and well I’m excited!(more…)
I’m trying to remain calm. I am an objective observer in the world of science and whatever the result, I will NOT let it cloud my emotions. I am neutral and I will remain that way… oh who am I kidding, I DID IT! Two years of planning and convincing people this would work. Then last night I had my first result, and it was a relief. It was a small step, but one I was afraid the data wouldn’t let me make.(more…)
Today is going to be a somewhat anxious day for me. It’s the day I get to crack open my data and see what spills out. There was a process to get to this point of course, it took me about a week, but today with just a few clicks I’m going to see if I have something or if my idea was never meant to be.Read more… if you dare!
Ever have an MRI or a CT done and thought, “I really wish I could do something with that.” Well you’re in luck! Today we’re going to do a quick rundown on how to take a medical scan and convert it to a workable 3D model. Something you could 3D print for example! As with everything else I do around here, this is done with free software so the only limitation is your access to medical scans, but we can get into a work around.(more…)
You know what’s boring? Going to the doctors office and getting an MRI. You sit there forever! Of course a CT scan is faster, but there’s still a lot of waiting involved and in the end, you get to see a quick glance of the images captured if you’re lucky. Where’s the fun in that? Well I’m here to help you do something with that information. Useful? Maybe. Fun? Definitely!(more…)
Well I didn’t plan for it, but today is a busy day! I’ve got a lot going on at the moment so not a lot of time to write. Let’s just talk about what I’ve done and have left to do so I can get back to it.(more…)
It’s a process… that’s for sure. So you’re a scientist and you collect a ton of data, well now what? We’re talking about me of course. I did it, I collected a ton of data and now I need to do something useful with it. This is the part I wish I could skip over and get to the part where I get all the cool results, but I guess we’ve all got to start somewhere.(more…)
Well it’s been two weeks (roughly) and my PI asked specifically that this week I do a review on the state of spinal cord research, with emphasis on the spinal cord stimulation work I’m doing. So this review is going to look slightly different, namely it has a rather long references section (15 total). If you find this research fascinating I recommend “And yet it moves” (reference 5). It’s long, but open access and worth the read. I’m a little bias though, my Co-PI is one of the authors. In any case, I had two weeks to write this, so hopefully it is a good dip into what we know about the spinal cord and a lot of what we don’t. Enjoy!
I scream it loudly from the mountain tops, I suffer all the fucking time from mental health issues. I do it because staying silent doesn’t keep me from feeling them and it does nothing for others who are suffering. Yes, it’s embarrassing to talk about it because it feels like a taboo, or something you’re making up, but that’s why we need to talk about it and why you need to keep track of your own mental health.
For those of you not in academia, summertime means we get interns in the lab to learn about how research works in a real-life setting. We typically have them help with things that require basic skills, but lets them see how research really happens. This year, we are doing everything virtually thanks to COVID-19. This is a great thing because it really means we’re doing what we can to stop the spread while still giving students a chance to experience research.
For the past week or so my PI has been away, so I’ve had the chance to work on other projects from home. Unfortunately he returns this week so I’ve got to switch gears from protests, working from home, and undergrad mentoring back to experiments and experimental setup. As the senior student in the lab, I’ve got a lot of responsibilities.
The world is on fire, we’re protesting for a future, but today I have my review paper due so instead of writing about my frustrations I’m going to share my review. Today we’re looking at the effects of trans-spinal direct current stimulation (tsDCS) on alpha motor neurons and how we can determine that effect using electromyography. It’s actually a very cool paper, the work is well done, and it’s open source so you can read it if you’re interested.
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.
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.
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!
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.
It’s day thirty-four in our spinal cord series. As usual, if you’re new here welcome and you can find each and every post in our series in the handy neuroanatomy category! All the posts are in reverse chronological order and while we don’t technically have a specific order, you should probably start with the medullary pyramids and work your way forward. If you’re here, then you probably are interested in the vestibulospinal tract, something we haven’t covered yet, but fear not, we are going to do that now.
Welcome to day thirty-three in our series. For those of you who are just finding us, we have every one of these posts in our neuroanatomy category in reverse chronological order. Today we’re going to backtract (get it?) a little and go over something basic, but something we’ve skipped over to this point. We never really talked about the landmarks of a spinal cord slice. So today, we are going to take a detour and go over spinal cord features.
Today is day thirty-two in our know your spinal cord series. If you’re just joining in, as I usually do in the intro, we have a whole neuroanatomy category just for these posts so you don’t have to dig for them! Today we are covering a couple of structures that fall under the same broad category, ramus. What are they and what do they have to do with the spinal cord? Well that’s what we’re about to find out!
Here we are at day thirty one of knowing your spinal cord and we’re still going strong. I’m very happy that I cataloged all of these posts in the super handy neuroanatomy category, which should make it easy for you to find each and every one of them! Today we’re talking about something we’ve touched on in the past, but deserves its own post, the spinal nerves. We need to cover this for the next couple of posts, where things get a little… odd. So let’s get started!
Welcome to day thirty of knowing your spinal cord. I feel like that is a lot of spinal cord knowledge for just covering the basics. In any case, if you’re just finding us, welcome! I’ve created a whole new neuroanatomy category just for these posts so you can find them easy and they are in reverse chronological order. Is the anterior white commissure a tract of the spinal cord? Well not really, but it does have an important job and we keep referencing it, so let’s talk about what it does exactly.
Day twenty-nine, wow does time fly! We have over four weeks worth of fun spinal knowledge for you to tap into, all in reverse chronological order in our handy neuroanatomy category! If you read the title, you know we’re back on tract (see what I did there?). Today we’re talking the spino-olivary tract, or is it the olivospinal tract? Keep reading to find out!
Here we are on day twenty-eight of knowing your spinal cord. A friendly reminder, the entire series has its own neuroanatomy category where you can catch up on any posts you missed or if you just want a reminder on something we already covered. We’ve already covered quite a bit of spinal disorders, but there is one more that I want to talk about and like our series where we started at the top of the cord and worked our way down, we are now going to cover damage to the bottom of the cord, specifically the cauda equina.
It’s day twenty-six already! For those of you who are just finding us, you can find all of the posts in our super cool neuroanatomy category. We’ve already covered a lot of spinal disorders, but one of the larger diseases that we have yet to cover is motor neuron disease. Technically a family of diseases, we will look at the commonalities and causes, so with that introduction, let’s get going.
Yesterday we had a bit of a break so I could share a critical review paper. That means this is day twenty-five of the know your spinal cord series! We’ve also hit the halfway mark in our 365 days of academia challenge! If you’re new here, you can find all of the fun spinal cord knowledge we’ve amassed by checking out our neuroanatomy category! We are going to take a step away from spinal cord disorders to talk about something we kind of covered, but deserves a more in-depth exploration. This is all you wanted to know about the H-reflex, so let’s dive in.
We’ve made it to day twenty-four of fun spinal cord knowledge! If you’re just joining us, we have a whole new neuroanatomy category for you to find all the posts in this series in reverse chronological order. If you want to know everything, then you’ll want to start at the beginning with the medullary pyramids. Over the past week in our series we’ve been talking about spinal cord disorders and today we are looking at something called tabes dorsalis, let’s begin!
