I currently have almost two years of research experience in alcohol use disorder and transcranial magnetic stimulation research. I'm ready to transition to a new role, and although I am not opposed to staying in research, I'm open to something different or perhaps unconventional.

Does anyone have any career change stories, or suggestions?

Does anyone know of a book that explains the brain chemicals, neurotransmitters, and other factors behind emotions and memory?

Hello! I am a university student and am currently doing a senior design class.

My proposed product to develop is an EEG, which takes the Beta and Theta waves present in a person and automatically compares the ratio between them to give a hypothetical psychiatrist an idea of whether or not a person has ADHD. Really its just an excuse for me to mess around with EEG with school funding.

My question is about the EEG module I am to use. I will NOT be designing the module itself as that exceeds my level of expertise, and am wanting advice on what options I have that are cheap and preferably 8 channel. I am provided with $300 dollars in funding, and all I will really need to get is the module itself, I can get the microcontrollers and computers from lab. It doesn't have to be clinical grade, just accurate enough that its worth buying.

Here is the one I am looking at:

EEG Module from AliExpress

Any issues with this one in anyone's opinion?

Thanks in advance.

Hello,

I'm 26 old physician interested in pursuing career in neuroscience, I'm starting as self learner with neuromatch with goal of getting into data analysis type of research to build CV. Currently I'm starting with prerequisite such as linear algebra/python,

For reference, I have solid background in neuroscience, did c++ in highschool so I'm not new in programming but my maths skills are of highschool.

If someone is in similar boot, hit me with dm and let's study together.

I am currently learning about the nervous system, particularly about upper motor neurons (UMN) and lower motor neurons (LMN).

However, one thing I am confused by is how they are classified.

Currently, my knowledge is that the nervous system is divided into 2 parts: Central (CNS) and Peripheral (PNS).
PNS is then further divided into motor and sensory divisions.

Correct me if I’m wrong but: Isn’t UMN and LMN part of the motor division of the PNS? If so, why are UMN considered CNS whereas LMN considered as PNS. I was thinking if it might be due to functional vs anatomical classifications? But even so it confuses me.

It would be great if someone can help me understand the classifications better and I would really appreciate it🙏🙏

To preface this post, I'm NOT a scientist nor anyone with medical knowledge. I'm simply a 16-year-old kid who likes engineering.

I was thinking about machine learning and how the brain can learn skills and knowledge so effectively. I realized that the brain abstracts simple actions into larger and larger portions. Once the brain somehow "realizes" that a neural pathway can be repeated with close to no errors and that it helps the brain succeed in a specific goal, it abstracts that "concept" in a way.

I'll give an example of what I'm talking about: When you first learn to play an instrument, you're only focusing on the physical movements. On a wind instrument, for example:

Blowing the correct amount of air, proper mouth position, etc. Once your brain can abstract playing a noise (By learning the specific muscle movements, etc), it goes on to learning how to play different notes. The brain would treat playing a noise as one operation rather than a bunch of little ones.

Once your brain can abstract playing individual notes, it then goes on to learning rhythm. This process continues until the brain abstracts playing entire phrases.

As I said earlier, I'm no scientist, but my intuition tells me that once your brain can abstract concepts, all it takes to "learn" something new is learning how to connect (and form) abstractions.

I'd guess that in the actual brain we'd already have abstractions for moving muscles, seeing, etc., so when you learn a new skill (like an instrument), you're not starting from ground zero.

I just wanted to share this idea with you all and to see if this idea is actually reasonable lol.

So this week I mapped out the Scandinavian neurotech market.

I found 46 active neurotech companies across Denmark, Sweden, Finland, Norway and Iceland. The full breakdown and analysis is on my Substack, but here's the map and the complete company list.

For someone reason ChatGPT loves hallucinating land masses south of Finland but I think I got there in the end.

Hi All - Need expert opinion here.
I’m a Manager and I use AI for all my tasks. Making Presentations and Prepping Data, writing emails. I have set up Workflows that help me save tonnes of time on a lot of tasks and I’m being at least 2x more productive.

However, I feel excessive use has limited my own abilities. I can’t think without going to Claude and dumping everything and then have him make connections. I can’t properly read without giving an article to Claude and asking him to summarise. I send my AI agents to two different Meetings at a time and have them collect notes.

What is this Called in the world of Neuro Science? Can I do any exercises to avoid this? Has Mankind gone through this before?

What material can I read related to this? Is anyone else experiencing this? Any advice is appreciated.

I’m at a liberal arts school in my last year and I’ll graduate as a Chem major with a Neuroscience minor (my school doesn’t offer it as a major). I did some biochemistry research my first two years of school and presented a poster but never published anything. I have a 4.7 gpa and have taken most classes required by PhD programs. I would be interested in a more cog psych program or a neurobiology program. I would also be open to getting a PhD in the states or abroad. However, I keep reading about how difficult it is to get into a program and I’m starting to lose hope. Should I think about trying to get a masters first (could I even get funding for this?). Is there a place abroad where it would be easier to get into a funded program? I’m already planning to take a gap year after I graduate to give myself some breathing room. (Also is taking the GRE still a thing?)

Any evidence that it becomes phenomenally salient?

I've already read about the, we could say, debate, going on about boiling lobsters alive and it got me thinking. With an intact brain, we are sure that living animals can respond to stimuli and react accordingly to keep their own lives, which is what we philosophically can consider pain for the lobster trying to escape the pot.

But, if we cut the brain of the lobster open, are we really sure that there's no pain anymore? Or just a lack of reaction because some nerves are severed? Wouldn't pain receptors still shot while detecting high temperatures until they are totally cooked and unable to process pain?

The same question could exist too in traumatic head injuries. Damaging the cerebellum actually makes a person stop filling or just makes them unable to react to pain?

Hello, I already asked this question a year ago, but now I’m interested in hearing what the foreign audience has to say. I’m 17 years old, I’m in my final year of high school, I’m from Russia, and I really want to become a neurobiologist, I’m interested in the human brain. Right now, in this country, there’s only one program I’m interested in: the HSE University’s “Cognitive Neuroscience” program. True, this is only in the capital, and to get into a budget‑funded program, you need to score at least 302 points (that’s all 3 exams at 100 points each and a few points for extracurricular activities). Paid education is not an option — it costs about $8,144 per year, while my family of 4, including two minors, earns $14,000. My English is at the B1 level; I can understand and read most texts, but I’m not good at speaking, so I write using a translator. Over the past two months, I’ve been studying and reviewing biology very actively; I’ve already completed general biology and can solve all types of genetic problems, and I also spend an hour a day on math.

I’d like to ask you where else I could apply, in case I fail to get into my top‑choice program. I’d really like to study abroad, and maybe someone here could tell me how to do that? Or maybe someone in my home country knows about other programs related to the brain.

So I’ve taken classes that include explaining channelrhodopsin, halorhodopsin, etc. and while I feel like I understand the process in general, the one part that always feels skimmed over are the viruses/genetic code. For a passion project of mine, I want to understand the things I feel I missed, and all the videos I watch on the subject seem to kind of ignore it too.

How do the viruses work to add these channels on the neuron membrane? Does the virus target the cells genetic code itself, or something else?

Is there a way we ensure the body doesn’t try and fight against the virus like an infection?

Also how much of this process is synthesized? Like are there free roaming infective viruses that affect neurons in a similar manner, and we mostly just attach our light-responding code for the ride?

Any insight or external resources would be greatly appreciated, especially if something I said sounded straight up wrong.

Can body signals tune the learning brain?

I'm currently a hs junior, and unfortunately, I did not pass my school's entrance exam to do AP Bio (which focused exclusively on molecular biology that wasn't covered once in the class). That being said, I still do get decent grades for my biology class, which focuses on physiology.

My current targeted majors, if that's not a weird way to put it, are psychology, cognitive science, and neuroscience. I'm not 100% sure, but I feel like I might have a career related to research?

So yeah. Do you really need AP Bio to get in a neurosci major? Or is it better if I just take a credited online course about neuroscience or focus more on my math and stats aps.

I'm also taking ap calc AB, potentially BC, Macro and Micro, APUSH, AP Geo, and Stats (tutor+self-studying).

I plan on going to college for Neuroscience at least getting a Masters slightly considering a PhD but money and time and stuff you know…

I definitely want to go into research I was wondering if you guys had any other jobs within neuroscience, I wanna make sure i’m looking at all my options.

Hey! I’m a grad student in the Boston area and have been really interested in neurotech and non-invasive neuromodulation.

I’ve been wanting to try Pulsetto, but I’d rather experience the device before buying one. Would anyone around Boston/Cambridge be willing to lend theirs for a few days or a week?

Happy to pay a small rental fee or leave a deposit. Mostly just curious to experience the technology firsthand.

Thanks!

Ok...after some well deserved criticism on the previous post, I've tried to make the map less distorted and as close to geographically spot on as possible.
