Anatomy, Physiology and Neuroscience

I got a question, that i just thought of. It seems to me that even after you die, for a time, the neurons in your brain are still in the same configuration they were while you were alive. Thus i would hypothesize that if we were to be able to interpret neuron activity for thoughts, and understand how to activate the brain mechanically, we could extract any data that is left in the brain even after a person has died.

In nerves the transmission of a message from the brain to wherever the message is going. Is it a electronic transmission? if it is Electric what frequencie/voltage is it?

Mouses apparently contribute to causing RSI, so how about keypads? Are keypads okay, or are waccoms the only solution. I'm using a laptop keyboard and as yet can't find a wristpad, but does it suffice if I simply raise the keyboard at the back, so as to create a slope? That way, there's no contact with the corners of the keyboard. Also, are there any exercises for RSI?

Is there an all natural suplement that you can take that is safe but still give you the fast results that steroids give. And if so can you buy them over the counter. I do not want steroids as they have alot of side effects,,but wish to have the fast results in a natural suplement. Any ideas?

Hi, I'm a little confused... Are Neurofibrillary tangles directly made up out of hyperphosphorylated Tau, or is it their formation that is CAUSED by the hyperphosphorylation of Tau? If so, then why is it that a more phosphate on Tau causes these tangles?

hi.I m MBBS student and want to postgraduate in neuro as physician.i have started neuroanatomy book by "SNELL".i give a little time to it everyday.please help me which books i should study the same time with it or next to it.or if one can help me about neuro videolecture sites.so i will be well prepared.i will be thankful.

What kind of research has been done on the spinal cord within the neck. More specifically the research regarding nerve impulses and mapping of nerve bundles to appropriate limbs?

I know what pancytopenia is, but i am wondering if anyone can give me an insight as to why it is termed "Trilineage". This should be an easy question for those doctors out there

we had a small group discussion in our class and our topic was this. we can't agree on which muscle is the most important for fecal continence. we argued whether its the internal or the external anal sphincter. I looked for it everywhere and I can't find the answer. sources don't specifically say it's the IAS or the EAS. if you know the answer, please help

Everyone knows the moon appears larger on the horizon. Before we even discuss this, I don't anyone to dismiss for a second that this is 100% a neurological effect and not some kind of actual optical effect perpetrated by the atmosphere. To dismiss the latter I offer the following: 1. Cameras do not observe the moon illusion. The moon appears the same size in photographs on the horizon or in the sky. 2. The size of the moon as projected by the lens of our eye onto our retina is constant no matter where in the sky the moon is located (~.55mm I believe, correct me if I'm wrong) Some wish to discuss the "theater" of consciousness (as in a Cartesian theater) but…

I don't know what to say on this, I was reading on piezoelectric effect in bone when I accidentally found this article saying that in a vacuum household scotch tape can produce X-rays. check it http://www.foxnews.com/story/0,2933,443470,00.html

Hi: The followings are not homework questions. They are question of my genuine interest. If all the pain receptors in the solar plexus are stimulated to the max-possible, will neurogenic shock occur? If so, what is the mechanism by which the pain will cause neurogenic shock? Is it lethal? Thanks, Green Xenon

Are neurons the only cells in the body that are capable of transmitting electric signals?

Besides Surgical procedures, is there any other way of getting rid of this condition?

The title of this thread describes the question. I am trying to come up with a "Magic" formula / flowchart which somebody could follow to try and make jokes. I am more importantly looking for patterns which could suggest certain things being associated with funny.

So, I went to Neuroscience 2009, which is hosted by the Society for Neuroscience. I visited today, which is Sunday, October 18th, 2009. Basically, the event is where a bunch of neuroscientists, scientists, and enthusiasts get together and observe and discuss information about neuroscience. When I got there, I had to obtain my badge. There was a mix-up, but that was quickly solved. Anyway, I received my badge. It had a nice little orange plastic underlining to it, which represented that I was a guest. Members had blue underlinings. It had my name on it, the university I attend, and on the back side was a number representing the member whom allowed me to be a g…

i know that this question has already been asked but i have done some research and i just cant figure it out.. i have just recently (the past two weeks) become obsessed with the smell of rubbing alcohol and a wet sponge. i always liked the smell of alcohol but this is out of hand. i cant stop thinking about either of them, i will take showers just to smell the sponge over and over again. and i carry a bottle of alcohol with me everwhere i read somewhere that it is a common thing for pregnant women but..my husband is in iraq, i cant be pregnant. i also read something about iron deficiency but i donate blood all the time and never once has my iron level been out…

I just finished reading a book where one of the characters was born without any eyes; no lids, sockets, etc. It got me wondering what it would be like to not have any eyes. What would that person "see" (for complete lack of a better term)? Normally a blind person would just see blackness, but if you actually didn't have eyes at all, you couldn't even see darkness; you couldn't even "see" nothing. This is probably something that only someone in that situation would know.

A recent video featured on ebaumsworld showed a French woman whose joints were so malformed that she moves about on all fours, resembling a quadruped. I was wondering what could possibly be wrong with her, medically. I only spent a little time searching on Google but I failed to find anything useful. Could anyone here enlighten me? Warning: The title/comments may be offensive (it is Ebaumsworld, after all )

I remember that I've heard of cases with stroke affected (I guess) patients who could see color but not form, and others who could see form but not color. However, I can't remember where I read it and my searches in several different databases have all comed up empty. Is there someone here who recognize what I'm talking about and could point me in the right direction? I need references which I in the end can put in a scientific paper.

wiki-A dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves, twelve thoracic nerves, five lumbar nerves and five sacral nerves. Each of these nerves relays sensation (including pain) from a particular region of skin to the brain. My understanding is that one spinal nerve contains bothe afferent and efferent fibers. So shouldn't a dermatome have an efferent compartment as well. Do dermatomes only have afferent fibres or is it simply that we consider only the afferent part as the dermatome of that spinal nerve. Thanks!!

can a living organism assimilate another organisms brain? like i mean if you were to drill a hole in your skull then add grey matter from a organism. could your body assimilate it, assuming no infection or regection.

A new app came out for iphone/ipod called Brain Beats. It is said to develop mental stimulation, spiritual exploration, self-help, and self-improvement. Can it really work? or is it just scam.. Id like to know what you guys think about that

My parents have an interesting question to pose after an acquaintance suffered a massive heart attack: is there a diagnostic method to detect artery clogs before they strike, besides an angiogram? Angiograms are, after all, a bit invasive for a routine test. (Though apparently it's fashionable in some countries to get regular angiograms, like they're colonoscopies.)

I hope this is the right place to put it. Anyway when I checked wikipedia it says Protraction is the movement of an anatomical part of the body forward (anteriorly) However in the scapula protraction is movement to left and retraction to the right. It is not forward bending. Then I checked some youtube videos and they do the test like wiki. I'm confused!! Thanks
