Until what age does brain plasticity still manifest? If it's real.. how come those of us who are poor in math are still poor in math and our brain math circuit ain't developing?

Hello, I'm new in the forum. I was just wondering, if the brain acts by sending electrical impulse, then the presence of a magnetic field should affect its motion right? Anyone knows how that affects its function? Depending of the answer I would have a couple of questions. Thank you

https://www.sciencedaily.com/releases/2017/01/170125093823.htm Does split brain split or not split consciousness or mind? Previously it showed it splitted the consciousness (one for each side of the brain).. but the above mentioned it didn't. What's your take of this?

Hello I have been reading Sean Carroll's book "From eternity to here" where he mentioned the concept of functioning brains emerging from random fluctuations on a quantum level due to the expansion of universe. They have been called Boltzmann brains https://en.wikipedia.org/wiki/Boltzmann_brain...

Hello, a certain sound remains in our brain for 1/10 of a second. The phenomenon of echo can happen only if the distance is at least 17 meters: we say the letter A, which remains in our brain for 1/10s, and the reflection (echo) of A arrives to our ear after that 0.1s...If the distance is...

Just curious if anyone else has sleep problems or other issues that particularly interfere with learning; and if so, what are your ways of coping with or minimizing these issues? Or if you like, on the positive side, of really helping your brain out w/ healthy habits? Some background on me: I...

Some activity you do while working to refresh your brain. It is actually a serious thing. I encourage anyone not familiar to learn about. I have desktop versions of field sports I play eg miniature basketball hoop, Velcro dart board, desktop catapults, and some mindless funny YouTube sub's eg...

Forgive me if this is in the wrong category or if there are any issues, this is my first post. My problem is that I need an idea for a brain project, as you may have noticed from the title. The class is a gifted enrichment course which, this year, is focused primarily on the brain. The gist of...

I'm not sure if this specific question has been already covered. If a person in his 60s who had been say, a painter all his life, decides to instead learn to play an instrument, what happens to the neural processes in his brain? Will the brain use brand-new neurons to create a brand new...

I know that SSRIs inhibit the reuptake of serotonin from synapses, and therefore cause the receptors on the postsynaptic neuron to be activated for a longer period of time. Does this have any effect on the signal sent? (for example, does it make it so the signal takes longer to process?, etc)

Hello everyone, I have been thinking about binaural beats, and after learning about the inner workings of the ear, there is something that I cannot explain. A binaural beat is the pulsating effect perceived by the brain when slightly offset frequencies are played in each ear. In my example...

For people who hit their head and suffer loss of mathematical and linguistic ability, does it also affect their emotional state? I met a woman who hit her head on table while falling down when she was 14 years old. Now she is 30+ years old. She said after the fall she can no longer comprehend...

Wikipedia states that "Savant syndrome results from damage to the left anterior temporal lobe, an area of the brain key in processing sensory input, recognizing objects and forming visual memories.", but if the area of the brain which processes sensory input get damaged how does the syndrome...

I am trying to wrap my head around the concept of schemas overall. I am sure my picture is far from clear, especially since the schema concept seems to have its own meaning from psychology and I've been sifting through different definitions. My current understanding is that certain neural...

Hi, I was wondering how synaptic pruning occurs? I understand the need for pruning, but how do connections in the brain just disappear? Are there molecules or enzymes that break neurone cells down, causing the loss of a connection, or is there some other mechanism? Thanks!

When I try to imagine face of some persons like relative,friend, celebrities etc. I can visualize them in my mind. I wonder how do brain decide what to show to me in my mind about that person? I might have seen the person at his/her various ages, various dresses, various places. While...

Hello, I know that the sensory cortex in the postcentral gyrus collects sensory information from different parts of the body, but in all the drawings and explanations, I see that it only gathers information from the surface of the body. Which part of the brain gathers information from our...

Does quantum gravity play role inside brain in ever changing perception of time?

Does anyone know if there has been any data on whether different emotions fire in different areas of the limbic system. Basically, are there "angry" neurons, and "sad" neurons, or to be more direct, neurons that fire exclusively when one is angry, and different neurons that always fire for when...

How many states of awareness can the brain be in? For example awake and conscious, asleep and unconscious, sub conscious. Are there any other states? Is there a point where the brain is in a state of all of them? And finally when a person is day dreaming is he both conscious and unconscious...

I went to a talk on nutrition recently which led me to do some research. Of particular interest to me is just what early humans ate, but I've also found a lot of uncertainty around what led to the evolution of the human brain. There seem to be a variety of arguments, from the claim that meat...

all of automate system in our body. digesting food, put oxygen on our blood and pull carbon dioxide out, immune system, wound healing...etc does our brain control all that even without our awareness? or those can still work even without brain order?if true... wow, our brain may inferior to...

https://www.sciencedaily.com/releases/2016/03/160316194205.htm Supplementation with the molecule pyruvate increases the energy reserves in the brain of aging mice, and makes them more energetic and keener to explore their surroundings. Should this be trialed on humans?

Homework Statement Which of the following is/are true regarding glucose transport to the brain? There could be multiple answers. a) Glucose uptake by the nerve cells of the brain is dependent on insulin b) Greater concentrations of glucose in the blood should increase the rate at which glucose...

A coworker of mine keeps mentioning Boltzmann Brains. I was never really interested until yesterday when reading Timeline of the Far Future on Wikipedia, which states the ultimate fate of the universe could be a Boltzmann Brain. Is this a theory scientists believe could really materialize?

Good day guys! I am looking for the handbook describing the various types of neurons in rat’s brain. Have you got something like this? I tried to find in google this information with these key words: nissl stain rat brain Accumbens neurons types and number of neurons in rat brain and...

So if I scan the brain precisely at the synapse level by observing the sodium firing, it is easy for me to obtain the result behind by a few milisecond, but what if I want to get the result ahead by a few milisecond, is it possible to predict a person's thought? And if the scan is my real brain...

If you raise the electron to other higher shell states, can light transmission throug -h a SOLID BLACK opaque object. Modified the original question because it was unclear. I won't repeat the same question over, and over, but what I have said in previous questions may get repeated in the...

I'm looking for an efficient way to scan the brain for synapses, my previous thread contain solution that suggested by injecting a virus to create solar roof on the neurons a sort of electromagnetic pulse can be detected to light up the neurons. Now I am looking for another way without having to...

What would happen if there is no brain plasticity? Would the brain be incapable of gaining new memory? Say you grow to a certain age, obtain enough memory, feeling, and such then the brain plasticity stops(yes, I know it is not supposed to), what would happen to that person? Is he still able to...

Hello; First of all I apologize in advance if I make any wrong quotes as I am a Mech engineering and has nothing to do with biology and DNA. I wish to know the entire code or the program of the DNA structure in human brain. As I understood DNA is made up of Adenine, thymine, cytosine and...

Is there any research that was done on animal long and short term memories? And short of empirical analysis, if there is none, is there much we could conclude, based purely on what we know about their brains? For example, from knowing which brain parts deal with explicit and which with...

I was thinking about drawbacks to high IQ, and I thought that maybe the increased glucose consumption from more difficult cognitive tasks could be one of those drawbacks. So a smarter brain could be in a way a "gas guzzler", which could leave you with decreased performance afterwards, which...

I am wondering if there is any consensus on the structure terminology of the brain. 1 - I've heard that the brain has the reptilian, mammalian(limbic) and neocortex parts that overall perform specific functions and evolved in that order. - On that note, would reptiles have had any really...

Am I the only one here that feels completely unable to do any hard work in the morning and afternoon times? If I try to get an early start on some math problems, then my brain feels very foggy. I just can't focus and think very deeply. But at night time I'm sharp and can work for hours. Does...

I am applying to graduate programs and I'm interested in biophysics, but I want to study the brain. I have yet to find a university that has a biophysics research project that is studying the brain/nervous system. Any information on people doing biophysics research concerning the brain would...

What type of technique would allow you to visualize the nerve electrical signal of the brain? Is it possible to do that with MRI?

Mods: I am not sure if this is a Physics question or more appropriate for Cosmology. I read a short discussion (on another forum) about the Boltzmann Brain paradox. I did a little further reading on the web but most explanations were a bit too deep (read: over my head). I wonder if someone...

What is the accepted interpretation of these two similar related issues: 1) When I am sleeping do my brain and body revert to un-collapsed wave state until and unless seen by a different observer? 2) I *never* have "seen" my brain - have the wave functions of the atoms and cells collapsed?

http://neurosciencenews.com/lymphatic-system-brain-neurobiology-2080/ can this explain why our immune system suffers when we are sad or down?

So I have downloaded the connectome of c.elegans for my own amusement; I have a few very simple neural models I want to implement. However they require some knowledge of the boundary conditions, i.e. given that a touch or temperature sensor on c.elegans has certain inputs, what is the incoming...

If heart forces 4 litres of blood per minute and blood pressure is 125 mm of Hg column and we consider pulse rate as 60 beats per minute then by calculation power of heart comes as approx. 1.111 watts. If I consider the person is just lying down and obviously brain is also active . My question...

After a degree in business and literature and a few years as a science writer in advertising, I'm going back to school for a second bachelor's. My idea is to go into a physics-related field. Ideally, I'd be an astrophysicist. I love physics and plan on graduate school, but knowing how many...

For instance, on fatal impact. Would you feel the impact before losing consciousness? I know myelin sheathed nerves will transmit over 100 metres a second.. The questions therefor are: A) How fast does unconsciousness occur? B) What speed does the brain recognize pain from nerve signals?

Hello guys, I was wondering if what this guy is talking in this video has some scientific evidence? And what he meant about the universe be in our brain?

in the case of information transfer or during reflex reaction, impulses pass through our body to brain. whether this has any relation with current in physics? whether vibrations are only passing? then how much is the speed through our blood?
