How much of the Human brain do we really use? I've heard that we use 15% and also 100%?Which is correct and why?Just curious.Thank you.Lord RaptorLord Raptor

suppose we have been light ,rocks,vegetables,animals,man.suppose that to develope into evolved man, we should start to believe that the only way is to "autoevolve", and suppose that every man could, (by it self and in a exponential mode ) start to use the power of the rest of its brain.

How does the brain accomplish such a feat as a photographic memory?BTW, a joke: "Everyone has a photographic memory, but some people just don't have film." I guess that means I don't have film. LOL.

I have old books but that doesn't matter.in one of this books there can be found this:Rubin laser is consisted of rubin cristal full of +ions,one mirror with full reflection and one with half reflection,impulsiv source of highly impulsiv light.when this light is released it goes thru the...

What exactly are brain waves? RF or other? what freq and strength if so?your not what you think you are what you think is what you are.

Poll Question:Would you like to have 200Gb additional storage as an brain implant?I've got understanding and intuitionagainst your authority and traditiondockChoices: yes no

I have seen numerous discussions here on the forum about where thought comes from. Some say thought comes apart from our brain, while others maintain that our brains generate thought. The argument that follows is that if certain parts of the brain are damaged, normal thought stops.I would like...

Fred Hoyle, in his book "The black cloud", explains the story of an interstellar cloud that has intelligence, is self-conscient, the particles that form its are its neurons. This cloud arrive to Earth an establish an interesting dialogue with its inhabitants.So, I have think in occassions that...

Poll Question:I was just wondering (i have add), do you have Add/Adhd? or have you beed diagnosed with a "disorder" affecting the brain of any kind?"There was a young lady named Bright,Whose speed was far faster than light.She left one dayIn a relative way,And returned home the previous night...

Hallucinations are usually defined as sensations having no basis in external reality. Voices, visions or phenomena that no one else acknowledges are generally relegated to the realm one's psychology. How would you justify, using your physics knowledge, an observation physically real to you...

I always wondered why we sleep? Is it more for physical reasons or does are brain need a rest.

"The Part of the Brain that Can Induce an Out-Of-Body Experiences Has Been Located"In short, "These observations indicate that OBEs and complex somatosensory illusions can be artificially induced by electrical stimulation of the cortex." and "Although we do not fully understand the neurological...

what's the brain mechanism of feeling 'funny', or knowing that sometihng if 'funny', or that for example a joke is 'funny' ?Thanks all out thereMinds Beat The Power(ADVERTISE HERE)

If we consider genes they are responsible for evoloution, however there cannot be any predefined evoloution so when the genes are passed from parent to young there must be some sort of record of sensory perception being passed also........Gods truths are not Gods denials!

Scientists have showed that average humans use about 10% of their brain capacity. And we've seen the effects, through einstein who was estimated to be able to use about 14% of his brain, that a slight increase has made with the development of his simple yet extremely significant theories.Now...

You might remember that in 1997 an epidemic of 'optically stimulated epileptic seizures' was caused by a Pok�mon video game broadcasted in Japan. The children watching the show had to be rushed to the hospital for treatment. I was wondering, what kind of effect does watching tv have on our...

How does our brain work exactly? Everything in the universe is made out of matter, fundamental particles - quarks, leptons and gauge bosons. So how do they give us the power to think?

which is an autoimmune disease, causing the inflammation of the brain. This morning on television I saw a girl where they remove the left half of the brain because of this. It was remarkable to see her sitting there as an apparently healty human being.Read this:A very interesting fact is that...

Most of you believe that our thoughts emanate from matter - that evolution has yielded a complex-brain, which, via chemical-reactions and electrical-impulses, yield 'thought'. Most of you also say that no 'organising-principle' is required for such a process. Indeed, you accredit this process to...

I move my finger. So, my brain must have told my fingers to move. Some chemicles were released in my brain and the such until eventually my finger moves. My question is what is before that. What is telling my brain to tell my finger to move???

forget about how they increase your risk of skin cancer, my question is: do they impair brain function by damaging brain cells? Maybe not from one visit, but over a series of visits? Someone said that and I had never heard anything about it before."In the construction of Immortal Fame you need...

Which one is left and which one is right?Dexterior SinisteriorWhy are chemists great for solving problems?They have all the solutions

Most people are here are probably familiar with neurotransmitters and receptors. Monoamines, glutamate, hormones, etc act as inhibitors or enhancers in neuronal AP firing processes in the synaptic pathways of the brain.I have some questions about the distribution of neuroreceptors. Is it true...

This is a very large topic.I'd like to start it off with an example of brain plasticity, that is by far the best example of what I'm talking about, that happened in Jolly Old England some years ago. It is an example that I continually site to Neuroscientists as an illustration of the plasticity...

Regarding human vision and the retina: Where are these channels produced? To put it simply, is it produced in the eye or in the brain. For example; does light enter the eye, hits the retina and it applies a series of filters to produce these 2 different channels (the parvo and magno) and it...

I think this refutes the standard picture since if ylour universe would just keep expanding we should be a Boltzmann brain. https://en.wikipedia.org/wiki/Boltzmann_brain https://arxiv.org/pdf/0802.0233 I would bet on the "big rip" (dark energy getting stronger) since that would also resolve...

My question on neurons and memory.

Hi, I’m an undergraduate student interested in cognitive processes. I’m about to ask a very interdisciplinary question, and so hopefully I can find a physicists that can take on the challenge. What is the fundamental reason behind why modern electronic computers (transistor computers) are...

Summary: A wood frog can freeze and then live again. What happens with the frog's brain, memories, etc? It is known that wood frog can freeze and subsequently resurrect and live on. Are any ideas about the personality after defrosting of frog? I mean this frog is technically dead more than a...

I've been wondering this for a while. It's usually noisy in my day to day environment so I usually play music in my earphones to help me concentrate, sometimes for hours. Would there be any negative effects to this besides loss of hearing? I feel as if music may overstimulate the brain though I...

Very cool paper just out relating fractal geometry to the representation of natural images in visual cortex. The main argument is that brain's representations are as high dimensional as they could possibly be without becoming fractal. https://www.nature.com/articles/s41586-019-1346-5 I'm...

Is it possible to solve the problem of which quantum mechanical interpretation is true, by sending the brain super imposed quantum mechanical signals. The individuals, perception of the signals, could identify which interpretation is correct. Could, an experiment of some sort be formulated with...

Scientists described using information from brain recordings to generate understandable speech in a proof of principle study. Invasive recordings of brain activity normally involved in the production of speech sounds, at the level of controlling muscle movement, have been associated with the...

The brain receives a lot of visual information some of which is redundant visual information. I am imagining it like the brain receiving a 1000 pixel wide by 1000 tall image of a road. The brain has received 1,000,000 bits/pixels of information. I am assuming the brain doesn't need all that...

Something a zombie would ask, or a co-worker looking to mine your brain for ideas? I thought pick your brain refers to mining, but my "comedic" retort of "you'll find no gems." fell flat lol, with a "I don't want to mine your brain." Maybe I'm a better poet than comedian 😀

We need quantum physics for cognitive neuroscience ?

I am fascinated by Einstein’s quote that the most unbelievable aspect of the universe was that it was intelligible. So my question is does anyone know whether it is so unlikely as to be absurd to suppose that random unguided processes could produce a rational brain in man in as little as 3...

My name is Chad and I am a senior level undergraduate Electrical Engineering major. I have an interest in physics as well and am doing undergraduate research currently on semiconductor materials that can convert beta particles into electrical energy. I am knowledgeable in the area of EM waves...

i read somewhere the body replace itself every 7 years. does the brain also do this?

Biologically speaking, why I'm not a cell in my brain, or just heart, I'm me as a whole. How lucky was I to be myself as a whole, not just another cell inside my body?

Brain cells from Alzheimer's patients have been found to have modifications of the amyloid precursor protein gene which forms plaques in the brains of people with Alzheimer’s disease. The modifications were duplications, partial deletions, and changes in sequence. This can result in multiple...

This article discusses some findings. The findings show a possibility: gut bacteria may coexist in the brain tissue of mammals. Humans are mammals. There is room for skepticism in the endeavor so far. Example: contamination of cadaver brain tissue samples. The reason for this position on...

Does glioblastoma, as the name suggests, affect only glial cells, or does it also impact neurons as well? Why does it spread so rapidly and effectively? And what modifications need to be done to the Zika virus to make it more effective at battling it?

MRI or other scanning techniques show how particular parts of the brain 'light up' when particular mental activities are going on. But then the video and sound of TV sets also depend on the patterns of electrical activities inside it. So different circuits are involved in images and sounds...

Hi, I am wondering if there is any brain exercises(possibly free) to do to make my brain more mentally fit and as best as it can be for myself. I want to exersize everything or all areas, making my brain balanced in every erea, specifically to improve memory and/or shot term memory to start...

I have a PhD in Molecular Neuroscience but am working on something that requires knowledge of electric field distribution in the brain. I understand that electric field intensity (V/cm) is E=(V1-V2)/d in a theoretical model (between 2 infinite plates, that are parallel and equidistant through a...
