Day 296: Review – Spinal Rhythm Generation by Step-Induced Feedback and Transcutaneous Posterior Root Stimulation in Complete Spinal Cord–Injured Individuals
Normally I’m somewhat excited to post these, but with everything going on you’ll have to pardon my lack of joy. However, it’s been two weeks so I need to review another paper so I’m sharing it here as well as sending my PI a copy. The study is a few years old, but it’s open access so you can read it if you’re interested. Transcutaneous spinal cord stimulation (TSS) is one part of my research in case you couldn’t tell from all the spinal cord and TSS studies and posts. I find it interesting and it gives me hope that we can help a whole lot of people living with spinal cord injury. Anyway give it a read and get out there and protest for a better world.
Day 282: Review – Transcutaneous spinal cord stimulation of the cervical cord modulates lumbar networks
It’s that time again! My biweekly critical review paper is due for my PI. He gets a copy and so do all of you. This is a particularly interesting study that falls in line with a lot of research that I am doing, so it’s interesting to see how other groups are progressing. Overall I think this is a great study and while it is behind a paywall, I think I summed it up very well. The drawing they did (above) is awesome, especially for a scientific journal where we normally use simple line figures. Anyway, let’s get to it.
Day 268: Review – Magnetospinography visualizes electrophysiological activity in the cervical spinal cord
Another two weeks, another critical review. This time I was more critical than review, unlike the last one where I was blown away at the possibilities. Why was I more critical with this one? Well in my opinion, the authors took a baby step when they should’ve taken a leap. All that aside, it is an interesting study and one I hope has several follow up experiments. This one is open access as well, so have a read for yourself if you’re interested.
Well we’re up against the wire now. Tomorrow is the due date for my paper and with it the video I am working on. Will I make it? How much work is left to do? Why am I talking in questions? Find out more… now…?
Well here we are and it’s… ♫ the finalllll count dowwwwwn!! ♫ My paper is due sunday at midnight and between the video I need to make, the data that still needs to be processed, and a shitty team mate who has done absolutely nothing to help, well I’ve got my work cut out for me.
Have you ever tried to learn something and you just can’t seem to get it to stick in your brain? That would be my life, well most of my adult life since I left the Marines. There is just so much knowledge in the world and wrapping my brain around even a fraction of a fraction of a fraction of that knowledge seems to be an impossible task. So what is one to do?
If you ever were to read one of my review papers, this one’s for you. It’s so awesome and falls in line fairly closely to the things I want to accomplish, albeit going a different route to get there. I’m super excited to share this with all of you and I hope I did the study justice in my summation and while I admit, I had far too much enthusiasm with this one, it shouldn’t take away from just how amazing this is, see for yourself! The study is open access too, so if you want to know more details, you can go take a look!
Well still quite a bit of work to do and some of it was frustrating, but here we are. So let’s run through what I’ve got left to do before the end of the term (ALREADY?!) and talk about the next few posts since I have somewhat of a plan… for once.
Today is the day, my group presentation is due. Is it done? Well… sort of? Okay not quite, but we’re getting there. My group member still sucks, but since I yelled at him (in a professional manner of course), he’s gotten a little better and has been more responsive, so what’s the hold up? What a great question, let me explain.
Well the apocalypse can’t stop the gears of education. Tomorrow is our final presentation for the class I am in, so there is work to be done and expectation maximization will come another day. For now let’s give a quick rundown of what I’m working on.
If we are going to talk about expectation maximization (now that I’m done complaining for a bit), we are going to have to introduce the idea of maximum likelihood. It’s going to be very easy to introduce, but it is a very powerful tool in estimating the state of something. Of course, it takes understanding a little bit of statistics, but trust me, if I can understand it, so can you.
I don’t want to jinx it, I really don’t, but I have an update on my group member situation and it isn’t completely awful! I mean, I’m still doing all the work and blah, blah, blah, but I’ve got an interesting story and I hope that things will be better now.
This will be my first conference since the pandemic and it will be a virtual one. To be completely honest, it wasn’t until yesterday that I was reminded we had one today. It’s a little bit different from our normal routine and I think that is what is throwing me off.
Okay I lied, I think we can do a better job explaining the Kalman filter, more importantly I have a fun little demo I can share with everyone. It’s not mine, but I like it a lot and it will give you a feel for what the kalman filter does. So let’s get started!
Since we’ve been talking a lot about it, I thought it might be a good idea to formally introduce the Kalman filter. This will be a semi-high level introduction (like my knowing your spinal cord series), but at the end of it you should have a relatively good feel for what a Kalman filter is.
I will not fail this class becuase of a shitty team member. I will not allow it, I’ve put too much effort and time into this class to do poorly at the last minute because my team member can’t be bothered to do the job he agreed to do. I suppose, this was… inevitable.
Okay, where the hell did that come from?! It’s almost the end of the school term. WHAT THE HELL!? It feels like we just got started, but my instructor just sent out the final assignment, which is due the last week of school… next week. I’m sort of freaking out right now.
It seems like it’s been non-stop for me left and right. I have experiments to do, papers to write, and classes to work on. With the pandemic I was hoping to get a chance to take a break, but nope it seems like I’m even busier than normal. I HAD thought that I was caught up finally when I finished processing some of the experimental data I had laying around, but nope I was reminded yesterday that I had not one, but two major deadlines coming.
Another day forward in our new normal. I’ve left the house exactly once in the last two weeks and while it’s nice not having to commute to school, I do miss living in a world without the constant fear of catching the virus. What day is it? Who knows, it doesn’t matter anymore. I do have some things coming up though, so let’s talk about experimenting in the age of COVID-19.
Day 239: Review – Burst-modulated waveforms optimize electrical stimuli for charge efficiency and fiber selectivity
Another two weeks, another critical review and as always since my PI gets a copy, so do you. Technically this should’ve come yesterday, but I really wanted to follow up with the Roosevelt mess going on. In any case today we are looking at something not quite spinal cord stimulation, but has applications in the spinal cord stimulation field. Let’s take a look!
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.
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.
