Anatomy, Physiology and Neuroscience

I have recently been researching brwainwave entrainment and am wondering if anyone knows any plans or schematics on how to build an EMF generator that could be used to entrain your brainwaves? Thanks Phil

Are there any neurological effects from having a pair of magnets stuck in your ears for a few hours at a time?

Hi all, as far as I know, it's a long established fact that when the human body is under stress (ie. someone is chasing you with a gun), it will be able to accomplish physical (and mental?) feats impossible under normal circumstances. I haven't read up on this or anything, so I am unaware if there are other factors to be considered, but I am under the impression that adrenaline plays the biggest role in this. However, there are differences. For example, you might be under stress to catch a train for work you can't afford to miss, so you'll run faster than you normaly would. But if a killer with a 9 mil was chasing you, I think we'd all agree you'd be running a lot f…

http://www.ireallyshouldstudy.com/health/2008/11/29/fat-sensing-hormones-might-fight-obesity/ +++++ So it seem some people body burns more fat in-take than others .One person will burn the fat of hamburger and fries faster than the other person? I thought obesity was a genetic problem.

Do any of you out there know if there is such a thing called smell illusions?

(The title will make sense later, I told one of the members that I'd name it this..) Lets talk about the birds and the bees. I was speaking to some people in the chat room about the difference between vaginal and anal sex. I believe that through a closer look at human anatomy one can conclude that our bodies seem to be geared and structured for the union of male and female genitalia via the vagina rather than the anus. Although many would say that there is no inherent meaning in the universe I believe that male and female bodies may actually be meant to be together as opposed to same sex couplings. I have gay friends and have experimented on both sides of the …

Episodic Memory is the is the memory of unique personal experiences. This along with Semantic memory make up declarative memory. For episodic memory to be stored the medial temporal lobe must be in function, this lobe also includes the hippocampus. Without the medial frontal lobe episodic memory can't be stored, presenting amnesia in some cases or memory loss. There is to debate as to where episodic memory is stored, some think it is the hippocampus where others think it it stays in the hippocampus for a while then moves to the neocortex to be consolidated. Semantic memory is the memory of knowledge based concepts. It is thought that semantic memory is indep…

Hello everyone, I would like to present here a model for consciousness that I have been working on... http://sites.google.com/site/hermesthephilosopher/Home Now half of it is quite philosophical, based on Heidegger, which is perhaps a bit tricky to understand. But I have tried to integrate this with evolutionary theory and some basic neuroanatomy, and I would like some feedback and discussion on this area (since this is a biology forum) . In particular I have attributed certain philosophical functions to cortical regions and am not entirely sure if they correlate - are these passable or have I misrepresented cortical functions? Here is an example from th…

Not sure how to ask this question...is there a particular area or section of the brain responsible for imagination? Daydreaming? Story-telling? I was hoping this was restricted to one particular area, one label, but I have a feeling it draws on multiple areas.

Not sure if this is the right place for this thread or not, so feel free to move it if I've posted in the wrong place. I was reading something a few months ago, can't remember what it was, but it was fiction, I remember that. A character was fatally wounded, a gunshot or something, in some cold climate. The character supposedly dies, but the freezing temperature preserves him enough that once he's found he's actually resuscitated momentarily and then dies for good. So, I was wondering if that sort of thing is remotely possible. Is there a "perfect wound" of sorts that would allow this scenario? In my mind, it seemed no different than a patient flat lining a…

Just recently, the son of Baseball great Ted Williams had his deceased father "frozen" in expectation of a future revival. At a cost of $120,000, one could have "whold-body freeze"; or for the cheap a "head freeze" for $50,000. Here’s how the procedure is done: After a declaration of death, the body is put on a heart-lung machine for transfer to the freezing facility. The body is cooled in an ice bath, the blood is replaced with a preservative solution, and as much water as possible is drawn out from the remains — so as to avoid cellular damage from ice crystals. Then the body (or just the head) is cooled to around 320 degrees below zero Fahrenheit, using a …

FIRST POSTING. For the last 14-15 years I have seen these very small pinpoint dots of ultra bright (really neon quality)violet lights. They will appear at any given time whether I am looking at people or just my immediate environment. Sometimes just one violet dot or other times a number of them variously positioned in my view, usually positioned at particular locations on a person or generally positioned just all around. I don't know what they are or what they could mean for me? Any help out there on this? CuriousMind

what is the best way to measure muscle density?

Hi all. Written English and chinese seem to me, a native spaniard; very memory intensive comparatively. In spanish, you do not have to memorize how to spell, words never heard before are easily written with no previous knowledge. A new written word can be pronounced properly with no previous knowledge. It is a fonetic language. You may not want to hear me to say the simple word 'focus' with my accent. That triggered this post. Well, ¿ would the forced memory exercising due to a language that is not fonetic play any role in better brain capabilities in lives of non fonetic speaking people ? Miguel

One of the best science fictions of all time was Frankenstien. But we all know that after the body is dead everything would have to be very well preserved for it to work. But how long could cells remain alive after an organism has died? The red blood cells would go first due to lack of breathing. But in any way, what else could we do to prevent or reverse death?

Hello everyone! Do letters or numbers have colors to you? I found a great synaesthesia voting website: http://www.tukan.extra.hu You can vote for the color of each letter and number and see what many other synesthetes voted for. I thought maybe we could discuss the results you can find there, for example, why A is red for most people?

Quantum physics and Consciousness. Are they connected? The microtubule connection. Research into the brain-body-mind problem is ongoing and one way of attempting to understand it is to try and describe consciousness in terms of material particles and fields interacting between inputs, internal states, and outputs without any intrinsic meaning. Terms such as “feeling”, “intention”, “knowing” and “choice” are thus not viewed as primary causal factors of consciousness, but a byproduct of these blind interactions. Quantum physics has not been at the forefront to attempt to describe consciousness as the neurocomputational model of laterally connected input layers of t…

Is there a neurologic disease where the person claims to see a dead parent or close friend?

iv been having some weird muscular and join pains of late and im not shure of what is causing it, im not shure its something worth going to the doctors about or wether it is, i ont realy now how to explain the pain its like a weak fealing as if the muscle is worn out and i dont get how, like for example right now siting in bed with my nees bent resting my labtop upon them im geting a feeling inmy calfs i think thats the name of the muscle the one behind the shin anyhow its been happening alot l8ly with my arms and legs and i was just wondering wether there is a simple explination like flew even tho i havent had normal flew like simptoms, or wether its worth contacting a…

One of my biggest problems with pathology is been able to describe a histology slide. I have tried several approaches to tackling these issues but have not succeeded in getting it right. So i am hoping that someone in this forum will point me in the right direction I.E, give a link to a site that shows this, or a book i can purchase (at a reasonable price) that will teach me how to describe histological slides. Cheers On the other hand, here is a typical example... of what i cant do http://www.microscopyu.com/galleries/pathology/chronicpneumonialarge.html I have two questions based on what is shown in that link... 1 - Can anyone of you describe the histologic…

I am interested in length of time/duration of a cough pulse width in a healthy individual. I understand that there is a range of durations based upon variables such as burst duration, expiratory volumes, accessory muscles, etc. Any help and references would be appreciated. JASMan

With the technology and knowledge we have today about the human body and how it works could it be possible for us to bring someone to life after being dead for a couple of hours.

Does anybody know what the main neuro-chemical(s) or horomone(s) are that are most closely associated with depression? What I mean is, in those who suffer from depression, what is the chemical that is found in excess while in a depressed state (or is it a deficiency in some chemical)? What about happiness? Also, is there an online chart listing the neuro-chemicals/horomones most closely associated with the whole set of human emotions? Or is this question too vague?

Hi Perhaps half an hour after a meal, when whatever is going on in the stomach, the digestion process is well advanced at a certain point of progress. Eating again at that moment mixes partially digested food with food in need of the entire process. What happens in that situation? ; how does the stomach recognizes what to 'continue' digesting and what to 'start' digesting ? Will the process start again and the already semi-processed food gets another 'treatment' ? Miguel
