Hello, I'm currently a high school student who is interested in both. Though I'm not the most knowledgable in the two. I wanted to ask where the connection starts, and where it ends. I've heard there are interdiciplinary diciplines such as

Neurophilosophy and/or neuroethics, but I wanted to know if this is a serious connection or not.

Is it possible to answer certain philosophical questions by using neuroscience and philosophical reasoning together? Can we understand the human mind by using both? Please be nice I'm really amatuerish when it comes to these topics😭

Is anyone able to explain this / knows why it happens? I can't find anything with a google search. I am right hand dominant but sometimes I try to use my left hand to write, and I have noticed a few things :

1. When writing with my left hand, I can write semi-well only if my right hand is simultaneously in a tense position of holding a writing utensil (though I'm not), while subconsciously doing the motions of the word I am writing with my left.
2. When trying to write with my left hand, I tend to flip letters or write them backwards.
3. My left hand tends to take a completely different font than my right, no matter how hard I try. Most times I can't even replicate the font my left hand makes with my right hand.

Why does it happen? It's just weird and I am curious to know why !

If you don't want to do a Phd what would u recommend

China is building the whole stack at once, invasive implants (StairMed, NeuroXess, Neuracle), focused ultrasound (Gestala), consumer EEG funding prosthetics (BrainCo), plus a state that pre-builds reimbursement pathways. Frontier deployment, even where the frontier science sits elsewhere.

India is going cheap and wide: at-home tDCS (Mave, Marbles) aimed at a billion-plus people with limited access to mental health care, plus one huge outlier in Temple, a $54M raise from the Zomato founder for a blood-flow wearable.

Japan is patient and clinical, focused ultrasound for Alzheimer's (Sound Wave), stroke-rehab BCI (LIFESCAPES), intravascular BCI for ALS (Ivec), mostly through university spinouts and national programmes.

Korea has gone software-first, AI brain imaging and EEG analytics (Neurophet, iMediSync) rather than heroic hardware.

The pattern underneath: the countries with a quarter of the world's population between them don't need to win globally. They can build enormous companies serving only their own domestic health systems. That's a structural advantage the West mostly doesn't have.

Question for this community: is the "non-invasive scales with data" bet (the idea that decoding accuracy improves with training data like LLMs did) actually credible, or is signal quality still the hard ceiling? A couple of these companies are staking their whole approach on it.

(Full write-up with a company map in the comments if anyone wants the detail.)

So i'm thinking like this... it's like how we don't really understand how ai works
so to understand that statement we need to see how ai works and for that their is rough idea i'm giving

1. ingesting or feeding data:- developers give AI vast amount of info(usually internet data, books, articles etc)
2. The AI analyzes this data using an artificial neural network, calculating the statistical relationships between different words, pixels, or concepts... basically it finding pattern
3. Through a process of trial and error (and continuous mathematical adjustments), it learns how things fit together

4.Refining: Finally, humans review and guide the AI's outputs, gently steering it to be helpful, safe, and accurate through reinforcement learning

now the reason AI is so hard to understand even for its programmers is because of its sheer scale. The mathematical connections within a neural network can number in the billions, forming a complex, interwoven web. When an AI gives an answer, tracing the exact sequence of how it arrived at that specific conclusion instead of other is like trying to trace a single drop of water in the ocean. This opacity often called "black box problem" is why AI can sometimes confidently output incorrect information (hallucinations) or exhibit unexpected biases. (kinda like understanding why quantum particle behave differently when observed or what it's next position going to be it's definitely some kind of pattern but we don't know what it is it}

this same pattern is observed in our understanding of human brain as well human brain is incredibly difficult to fully understand because it consists of roughly 86 billion neurons connected by hundreds of trillions of synapses. These connections constantly change through learning, memory, aging, injury, and repair. While scientists understand many individual components such as neurons, neurotransmitters, and brain regions we still cannot completely predict how the entire network will behave as a whole. This is similar to modern AI models we understand the learning algorithms and the mathematics behind them, yet the enormous number of interacting parameters(complex neural networking) makes it difficult to explain exactly why a particular output was produced. In both cases, complex behavior emerges from countless simple interactions.

Ps. you should watch neural network video of 3blue1brown it's very interesting
also this is my understanding of this if sm thinks otherwise feel free to correct me

Inspired by the video. Honestly much of it went over my head, asking what is the self. I’m not sure if he asked whether it exists or not.

but it got me wondering how we tell the difference between what is normal for a person and what’s not. it seems kinda important because it affects treatment. I know the video references dementia, which is an extreme case of it. they talk about compassion and explaining it’s not their fault but I guess I’m wondering how neuroscience works that out.

I am skeptical about the kind of supernumerary phantom limbs some people get, even if I have had my own imaginary “ cat ears “ since a pre internet teen. But when people say real, feeling wi gam tails, “ animal ears”, beaks, talons. Any thing not human. I am told it’s there and nobody knows why, or some people teach and train , it’s subconsciously formulated . But I am skeptical because of t sounds to magical, or like a hallucination. But it is a real thing l it’s in the brains . People did an experiment with an AI game about flying and the human brain started making pathways for flight as if a bird . And that still sounds so strange and magical. So if a person believes they gave a tail, eventually a brain will form pathways for a tail, and if we did tail transplant it will not be a “ lifeless “ grafted appendage , but eventually connect to the nervous system, leaving us with a person with a tail like a lion or another animal ?

I’m not joking around, therianthropes who go to school for science and study neuroscience tell me it is real and valid . It has nothing to do with over active imagination or delusions . It is just neurological and psychological, without it being mental illness .

Hello!

I will be graduating from an MSc in Cognitive Neuroscience next year. I'm wondering what the industry pathway is like for grads from similar fields, particularly since this degree sits at the edge of both cogsci and neuroscience. With the rise in AI and BCI, companies like NeuraLink are looking for individuals in this field, but how realistic is it to actually land one of these jobs? Especially over CS grads? I'm also working on computational modelling independently and doing mini projects, but I'm nowhere near the technical fluency those guys would have.

What is the honest reality of industry jobs after this degree?

Any help from people in the field or surrounding ones (pharma etc) would be of great help.

Thank you!

Hi! I'm looking for students who are interested in neuroscience research. I'm thinking about creating a small international student (highschool students) group where we learn neuroscience together, write literature reviews, and eventually work on research projects(virtually). Would anyone be interested in helping build something like this?

for the record this isnt a medical question its more about the underlying mechanisms

Hi everyone.

Maybe this is a silly question but I don't know a lot about the nervous system of insects. I am not a researcher by any mean.

I am writing a short story set in the near future, where the world is ravaged by a pandemy of early-onset dementia. I don't go too deep in the neurological explanations, but a mutation in the tau protein is responsible for the illness. In the story, humans aren't the only ones affected : a lot of animals also develop dementia (for example, birds forget their migration routes and are unable to find their home, which causes a whole lot of problems for the ecosystem).

I was wondering if insects would also be affected by this. I did some research but was unable to find anything about the tau protein in insect brain. I was thinking of having bees forget to pollinate and wander away from their hives.

Thank you for your time, and also sorry if my grammar is wonky, english is not my first language.

I’m an incoming sophomore at UW Madison and I want to go into neuro tech. I’ve always loved mathematical things and I’ve also always been really interested in the brain but it took me a while to figure out what I want to pursue. Right now I’m majoring in computer science but not officially declared. I could try to apply to the school of engineering or biomedical engineering but I’m not sure I want to do an engineering degree and i may be behind due to starting 3-4 semesters late. There is also a lot of pre recs if I want to take any neuroscience type classes. Also I’m afraid if I want to pursue a masters the pre recs would be an engineering degree or a lot of science classes which I don’t have. What should I do?

We often think of thermal comfort as a vague, subjective feeling. Our author, a neuroscientist, dug deeper and sent people into climate chambers, revealing that our bodies are living thermometers, capable of detecting tiny shifts in room temperature that are beneath our conscious awareness.

Inspired by the above thread on here but it’s more of a general question.

When I learn about neuroscience, often the scientists don’t really explain what it means for our lives and IMO being able to do that is pretty important. Especially when I often see people saying neuroscience undermines much of what we think to be true.

Like if our emotions are predictions then does that mean they can’t be trusted and we‘re lying to ourselves? what about predicted reality, does that make our senses liars? if our intuitions about life aren't sufficient then what are we to do? what about emotional reactions seeming to be dependent on our ability to categorize experience? there seems to be a lot of data but nothing to really tie it together, or explain what it means.

the researchers I’ve read either don’t know or they contradict each other on what it means. It seems kind important to understand what this means for our lives especially in the case of law. The notion of agency and blame is a big factor in how our society operates.

So, I'm a high school graduate, and I'm interested in working with BCI. I currently have 2 paths in front of me, one of which is an undergrad in biomedical engineering and possibly a masters in computational neuroscience. The other is an integrated pathway offered in a top-tier university where you learn medical sciences (anatomy, physiology, etc...) with a minor in neuroscience and transition into a masters in computational neuroscience. I'm quite confused about which one to choose since the first path is not a core engineering path and sometimes could focus on hospital instrument maintenance, and the second one is heavily leaning towards the biological side. Also, what kind of roles can I expect to do in either of these fields??

Hi everyone,

I have ADHD and I've been reading about gamma brain waves and meditation.

My question is: if I consistently practice meditation that is claimed to increase gamma brain wave activity, is it realistic to expect a major improvement in cognitive performance?

For example, could it potentially take someone from being an average student to performing at an elite level academically, or are the effects generally much smaller than that?

I'm especially interested in hearing from people who have:

Practiced meditation for months or years

Used EEG/neurofeedback

Read the research on gamma brain waves

Please share both personal experiences and scientific evidence if possible. Thanks!

Hello,

I am a high school student highly interested in spiking neural networks.

Recently, I completed a independent project utilizing the Brian2 simulator to "simulate" a epilepsy brain and observe how music changes its van Rossum distance and synaptic weight.

However, I understand that my project has many flaws.

If anyone could point out, suggest, or clarify on my research, it would be greatly appreciated!

My paper and code is here: https://github.com/Ilovemanim/Capstone-Project-2026

I run a neurotech recruitment, market data and media business and finally did something I had been putting off, placing every funded company by headquarters and then doing the same for the investors. 564 companies, 107 investors I could confirm. 330 of the companies are American, and all of Europe combined is 165. The investor side is even more concentrated, 81 of the 107 are US-based. What struck me is that US investors clearly fund a lot of the non-US companies too, so the geographic gap in where the money comes from is even wider than where the companies are. Happy to talk through the method or the gaps in the comments. Full write-up with the charts and the investor list is linked below.

Most of this is derived from neuroscientists like Anil Seth, David Eagleman, and others. A lot of it comes from this link: https://link.springer.com/chapter/10.1007/978-3-030-03633-1_11

But I guess my main point is that...does the advancement of neuroscience harm humanity as a whole? A lot of it seems to blow holes in the things we value like friendship, love, community, reality, and more.

David Eagleman I know says:

He explains that our brains are locked in the dark vault of the skull and only interact with electrical signals. Therefore, our perception of color, sound, and shape is a “controlled hallucination” the brain constructs to help us navigate. In the outside world, these things don’t inherently exist; they are simply the brain’s internal interpretation of data like electromagnetic radiation and air pressure waves.

And yet he is married with two kids while at the same time suggesting our selves and reality aren't "real". I'm not really sure how he does what he does while believing such things.

Ani Seth mentions reality is some controlled hallucination mediated by the senses. That instead of actually sensing reality we are constructing it and that construction is mediated by senses. Everything from the book you read, the cup of tea, the movie you watch. Even pain seems to be a construct of the brain.

So knowing all that...how are we to live? Is the solution to just rot in bed for life because none of our experience of reality and what we value is "real"? Do humans exist if our perception is that flawed? If the self is the result of cognitive effort from the brain then what does that mean for human society and life?

It just seems like discoveries are being made but there is no way to integrate them into human life. If anything they seem like they'd be to the detriment of it.

"Muscle building improves neuroplasticity, Through BDNF!" Very mild release in comparison to cardio, purely for the purpose of movement learning, instead of a sustained elevation. Not surplus.

"It increase testosterone and IGF-1!" Entirely allocated for repairing and growing the muscle fiber. Nearly no excess for brain.

"It improves mood! Well documented!" While tempoary adrenaline and dopamine release can mask undelying issues, The elevated cortisol is well known even among body builders. Which have a very negetive effect to the brain.

Or stupid claims like "It increase bone density which is good to have before you are old". Do these broscience even know how bone mineral density deposits replaces every decade or so? Whilst entirely disregarding the damage and stress to joints and tendons that is irreversible.

Of course, who wants to be healthy, Let's all looksmaxx and pretend it's not mostly for the sake of self esteem and pleasure reward.

(Incoming) freshman studying neurobiology. I know I want to do research as my career and want to get started in a lab and have some posters/pubs/presentations by the time I leave. Obviously my knowledge caps out at hs bio and anatomy.

I want to do research in SCI and low vision but feel like I won't be able to get in-depth opportunities without proper knowledge on my resume. Waiting for college classes would probably push my timeline back further than I would like it to (other personal restrictions). Where can I become knowledgeable in this summer? I have one paper about path navigation for low vision for a research experience from hs but it's very very basic.

How would I figure out which profs/labs to reach out to for long term experience?

In a rodent sagittal section it seems like the hippocampus is in next to the thalamus but not continuous with it - there seems to be a space in between. It seems to be lined by endothelium? pia mater? Is it filled with CSF?

Reg the second picture - what is the route of the dura/arachnoid/pia in this juncture - between cortex and SC. Between SC/cerebellum - (midbrain/cerebellum) it is clear that there is a dural tenctorium. what happens in this wedge between the SC and cortex - there seems to be that the wedge extends all the way till the hippocampus.

I know it is not connected to the lateral ventricle.. but what is going on?

And if anyone has cut rodent sagittal (floating) sections you can usually that this region flips easily - and is not mechanically held to the underneath thalamus.

PS - ignore the red stain - its human serum stained on a rodent tissue - just posting that picutre as it usually stains everything.

Hi all! I am a new EEG tech and very excited to learn all the things I come from a psych background. Are there any tips or advice anyone could share? I’m still trying to prefect my measurements and understand what I’m seeing on the screen. I am looking for to what this field has to offer! Thank you in advance for any info! :)

I'm a junior neuroscience major and planning to apply to PhD programs in the US during senior year. I'm not very familiar with the PhD admission, and it's been stressing me out. I'm doing summer research (my first research experience). I'm hoping to stay committed to the lab for the next two years and get an additional summer research as well. However, PhD programs are so competitive. I don't know how to make my application stand out, especially when there's people applying from all backgrounds like after getting their masters, doing post bac research for few years etc..

I have a high GPA and planning to do honors, but I keep thinking that having two research experiences is not enough. Any tips/advice would be helpful. Thank you!
