Brain Definition and 740 Threads

I have sought information about different approaches(fields) to neuroscience and how they differ in terms of understanding how the brain works. I'm interested to learn more about neurobiophysics, computational neuroscience and engineering perspectives. In engineering especially about brain...

Brain Stem -- Posterior Anatomy Question On the Brain Stem is the Pons and the back of the Pons connects to The Cerebellum. The part that connects the Pons to the Cerebellum Is this The Third Ventricle? But if you look at a photo on google it shows a line going up the back of the whole...

Hello, I am a mathematician and i have a personal theory of consciousness. Now, i DID read the rules for the forum, and i am aware that you guys don't want to be bothered with this, up to a point. However, i have isolated a key part of my theory in what are possibly satisfactory physical...

Does The Cerebellum mean Little Brain or Tree Of Life?

My brain has been shocked by this problem dealing with charges and Coulombs law :( This is what I did... F = k*q1*q2/r^2 F = [ (8.99 * 10^9)(4.9 * 10-9)(6.0 * 10^-9) ] / (0.295)^2 F = 0.000000264 / 0.087025 F = 0.0000003034 F = 3.034 * 10^-7 N F = k*q1*q3/r^2 F = [ (8.99 *...

Lots of us have drank to the point where, the following day, we didn't remember a significant portion of the night prior. What happens in our brain? Does it not record memories after a certain blood-alcohol level or does it put those memories in the back storage of our brain, where they can't be...

Maybe the sheer size of the universe? The speed at which light travels? The size of a quark? Out of all the things in the universe, what is hardest for you to possibly imagine, as long as it's generally accepted it doesn't have to be proven. For me it's both the size of the universe and...

I'm doing double honours in Neuroscience, likely biochemistry as well. I have to find a thesis adviser for next year...I know everyone says "follow your heart" or something to that effect, but that's not what I'm looking for, not to impugn anyone will kind intent. Here's my interested in Med...

Is the Reptilian Brain midbrain the same thing? I know at the top of the Spinale Cord is a little Ball and this is the Midbrain. Is this not what they call the Reptilian Brain?

Hello, I was interested in human consciousness, and I picked up Daniel Dennett's book "Consciousness Explained" and something he claims there got me thinking: He says that human brain evolved from chimp-size to homo-sapiens-size in a period after humans learned to stand on 2 feet, and before...

Possibly I'm misinformed, but adrenal glands make us feel excited, sex glands (whatever their name) makes us feel the appropriate (or not, depending on your situation) emotions. Maybe to rephrase, how emotional is the brain on its own? And possibly, how important are these emotions or...

ive been practising relativity questions and there's one i can't do, I've tried loads of ways of approaching it and i can't go any further hence asking for help it says " the diameter of the Earth's orbit is 3.0 x 10^8 m. a spaceship crosses the orbit in 750s, as measured in the spaceship...

Hey everyone, I would like to first point out I am not a biology major in any way...I am a physics major, with a ever increasing interest in neuroscience. I am trying my best right now to find ways that I can incorporate my physics knowledge to the brain. Right now I am trying to...

I was told I could do a directed study of my own choosing because of some projects I did last year that went over very well. My area of interest besides physics is neuroscience. My education is mainly Physics, but I have been working with some people in the neuroscience lab (who all...

For an occasional/recreational user, is alcohol consumption once in a while harmful for your brain? I googled and i couldn't really find a straight answer, i read somewhere a while back though that Richard feynman never drank alcohol or did any drugs(he wanted to experiment with LSD) because he...

Is neural oscillation the only method in which we can analyze and communicate with the brain?

If I close my eyes (so as to remove my sense of sight) and spread my fingers so they do not touch (so as to remove sense of feeling) and then move my hand around, I still have a sense of where in space it is located. How is my brain figuring out the location of my hand under these conditions?

Hello! The other day, i was referring to some comic book and it said something about telepathy which made me wonder if the heart and brain really emit signals thaat are powerful enough to be able to be caught or processed? if yes, how... Elaborate help shall be acknowledged... Thanks

There has been quite a few studies on the difference in the neuralanatomy pertaining to ADHD/ADD patients. Can we use this for a more objective test for ADD/ADHD on patients...

If you look at the Human Brain and you see the Brain Steam can you see the Pons on\f the Brain Steam or is this part very close to the bottum of the Brain? I ask because some Models show it and other do not but in real life can you see the Pons of the Brain Steam?

Dolphins have larger brains than humans. So, why aren't they smarter than humans... or, are they? Are those sneaky Dolphins playing dumb? j/k It's my (very limited) understanding that the cortex is responsible for the higher levels of what we think of as intelligence. So, what's different...

I've got mathematics as one of the courses in my engineering programme. I love maths. However i don't enjoy working my guts out to ''if...then prove that...'' problems which are kind of brain teasers and brain teasers only. Their solutions often involve leibniz's rule of higher order derivative...

Müller's law seems to differ from the modern statement of the law in one key way. Müller attributed the quality of an experience to some specific quality of the energy in the nerves. For example, the visual experience from light shining into the eye, or from a poke in the eye, arises from some...

I'm curious to know how much energy a brain will use depending on the different activities it's doing. Sleeping vs. watching TV vs. doing rigorous physics problems vs. running a marathon For the above activities, what are the different energy requirements like? How do the things...

super important for science- What's the relationship between Al and H2O Does the insertion of aluminum rods into a beaker of water affect the time it takes for the temperature of the water to reach 75 degrees Celsius when heated? I believe it would because there is more mass but I'm not...

Alright. So the Dirac Eq is (i \gamma^{\mu} \partial_{\mu} - m) \psi = 0 or putting the time part on one side with everything else on the other and multiplying by \gamma^0 , i \partial_t \psi = (i \gamma^0 \vec{\gamma} \cdot \nabla + \gamma^0 m) \psi I would think that this is the...

I am reading a lot on the Hippocampus of the Human Brain and I understand what it does. But I looked on Wikapedia and google and all over trying to find a good photo of where it is and the shape of it. I can not see any good pictures or anything can anyone help?

"Brain Drain," summer jobs, advice Hi everyone. School is coming to a close, and I'll be graduating from HS next month. I thought that I should make a little post about my summer plans. I will be attending college this August, and I will be moving out from home (definitely a new experience...

http://www.gatech.edu/newsroom/release.html?nid=128531 Browsing the alumni stuff, I see things that make me wish I were back in school. You kids and faculty are so lucky to be able to do this kind of stuff every day. I have serious envy! Alas, wife, kids, house, bills, argh. Nothing but work...

I'm starting to develop some kind of obsession with being smart and some of you may have read my previous posts about it lol but I do have one question. What makes brains like that of Daniel Tammets to be incredible behond scientific understanding? How can he solve extreme mathematical...

That is, conscious decisions are said to be regulated by the prefrontal cortex, whereas inherited reactions (fear of snakes, etc.) are more regulated by the hypothalamus and the amygdala. (Yes, I am aware that this is something of a simplification, but this is valid enough for my question, I...

Hi there. I have read that quantum particles change when we observe them, Does this mean, nothing in the universe is as it is unless we observe it? If so then how can the planets that give life exist before we observe them? I am sure I sound like an idiot, but I hope you can understand my...

Below are two excellent papers that outline the mechanism by which astrocytes regulate synaptic strength. The first one shows the most important pathway, I think. Here's my summary of the story from the first paper: 1) ATP released locally by local activity (either from the granule neurons...

I recently started a (self study) degree in physics and I'm enjoying it so far, but I feel like my brain has turned to mush. I've been out of education for a while but back when I was in school and college, I could pick new things up really easily, do big calculations in my head, etc. but I just...

I had a brain teaser that I was hoping you could solve: "In order to guarantee all emergency call are received, the phone company wants all phone nubers with 9 follower by 2 1's to be routed to 9-1-1 emergency center. This will ensure that any real emergency victims will still get help they...

I've always wanted to study something that has to do with how information is processed in the brain. I don't know if this sounds silly but almost like "reading" the brain. Perhaps like data/mathematical modelling? I don't really know what educational path I must choose. I am thinking that the...

What are the current accepted paradigms on concentration and Focus? I want to know more information about it, links are also greatly appreciated. Sometimes I can study for a very long-period of time with complete concentration. And other times I just can't seem to focus as much as I would...

Ok, so my room mate and I were talking and came up with this question. What would happen if you placed a smaller pressure cooker inside of a larger one? Both are rated for the same temp and pressure. Would the one inside reach double the psi? Would it blow up?

Hi all, I have some history in practical electrochemistry, and have, I think, a reasonable uderstanding of the basics of Redox reactions and ½ cells. Recently, I have been thinking about a project, and it has me in a complete quandry. There’s probably something obvious that I’m missing, but...

So I'm reading an example from my text on how to construct an isomorphism: Let V be in R^3 be defined by the single linear equation: x1 - x2 + x3 = 0 (those are suppose to be subscripts after the x's) and let W be in R^3 be the subspace defined by the single linear equation 2x1 + x2 - x3 = 0...

I remember in my earlier days of math classes all throughout school up until my latter years of high school, I did very well without even trying. I literally never studied for tests even once, and I only opened the textbook to rush through the homework in 10 minutes so I could play computer...

Hi Do the experts on this forum think that it is possible for there to be special particles scattered throughout the volume of a living human brain which together form a single permanent quantum entanglement which lasts at least as long as the lifetime of the brain? If yes, what do you think...

I heard in psychology class today that the brain supposedly doesn't operate in a quantum way. Not sure what my teacher meant about that, but my class is stupid and so is she. The textbook and my teacher even claim that parts of the brain are highly specialized into areas for different tasks with...

Hi all :) I was thinking earlier about if people are born a genius or they become a genius due to the way they think. I consider the hardest thing in the world to learn is math / physics and almost every genius or extremely smart people always excel in these fields. I am terrible at maths and...

At what point, or scale, do organisms/lifeforms/whatever have brains?

Animal Brain size, body mass, and surface area S.J. Gould wrote a series of interesting articles (chapters 22-24 in Ever Since Darwin) about the ratio of body mass to brain mass among animal species. Bigger animals have bigger brains (of course) but the ratio is getting smaller: a human's brain...

Which weighs more -- the human brain or the remainder of nerves in the human body?

I am doing a zainy experiment at home. I need to devise a way of applying a cooling intensity factor (CIF) of around 70 mW/cm2. I need to cool material that is roughly 30 degrees Celsius down to around 2 degrees Celsius. The cooling has to last for a period of one hour or more. The surface...

Some interesting information and mental tests.
