Anatomy, Physiology and Neuroscience

There have been many innovations in neuroscience lately, it seems as if the brain can't hold its secrets from us for long. From the first brain prosthesis:

which nootropics in your opinions is the best piracitam and ritaline and a herb named ginko are the only ones available in my country but do tell about other nootropics too i have adhd,ocd and aspergers syndrome will it help in reducing their symptoms too?

Hey guys. Im a high school student and I need an article for my research. Can sum1 help me get it? I dont have access to colleges right now so i cant get it. Thanx for your help. The title of the article is: A reassessment of the neurotoxicity of pyrethroid insecticides. Ray DE, Fry JR. here's the abstract of the article: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16324748&query_hl=1&itool=pubmed_docsum

would there be the possibilty of recording the neuro-electrical calls made to the brain by persons waking from sleep, and derieving a pattern from such data. then use it to stimulate or use as playback introduced into the brains of coma victims to induce wakefulness. yes i understand moral implications, but as a measure of last resort. would imagine patterns developed from siblings and parents of coma victim would provide best source. strange thoughts mr d

Hi everybody! I've not been on the SFN forums during the last months, but today I read about an issue that fits quite well into the neuroscience forum I think. It's from a German website, so the text is in German, but I will translate the part I am talking about. Let's begin: From: http://www.karl-leisner-jugend.de/Hinweise%20auf%20Gott.htm What do you think about this? Is the description of the brain structure and of those free synpases correct? Well, at least a Nobel prize winner talks about it... but what about the interpretation that they are receivers for a soul? Are there really no other explanations for them? Why isn't this topic more talked …

i need some help about my father he got braing hoamorage in 1999. and his right side got paralyised. after physcio therpy treatments and occupanture tratmetn for some tiems.. he got lil better..his age was 55 at that time.. now after five years he got minor attack again.. and he cannot eat anything. infact taking liquid is a big problem... food comes out of his mouth.. me n my family all are upset.. i just want some suggestion to get his condiotn lil better if possble. thnaking u all in anticipation my yahoo id moonrubyainy@yahoo.com

When one's foot or hand falls asleep, one usually experiences what is commonly called "pins and needles". Does this sensation come directly from the epidermis, or does it originate in the brain. If I didn't know that the "falling asleep" of the hand or foot consisted of the local nerves becoming non-responsive, I'd assume it originated from the epidermis of the hand or foot. However, if all sensation from the hand or foot is cut off due to the non-responsiveness of the nerves, then how could these pins and needles come from the hand or foot. I've heard of phantom limb phenomena, where an amputated limb is still felt because the brain centers for tactile sensation of that …

Does anyone have an opinion or personal experience with new medical treatments for alcoholism, i.e., the manipulation of neurotransmitters with medicines such as Campral or Gabatril? I believe the correct answer is out there and there aren't enough addicts motivated to recover (scientifically) or have the forum to share this information. I have been studying this area since 1996, have no college education, but can talk intelligently about it. (Currently sober recovering alcoholic)

Ran across a neat article about using technology to cool or heat the body (cool, mostly) to avoid problems that occur when the core temperature gets away from its nominal value.

I am currently a freshman enrolled at UF and have just completed my first semester as a biology major. Offered at my school is an interdisciplinary degree in neurobiological sciences which includes mostly upper-level psych coursework and the core sciences and has an emphasis on research. I have read several books in this subject area and the work definately appeals to me. I've always considered medical school as my first option but I was wondering what other opportunities this degree could afford me post graduation such as further education and of course job opportunities. Being that this is a degree you have to work towards and apply for at my school I really don't know …

Burns - Longer Healing Time? Why do burns take longer too heal than cuts? I have had some big cuts but even the small burns normally take longer too heal than the big cuuts - why is this? Just curious, not for anyhting but my own interest Cheers, Ryan Jones

So today I got my self out in the blinding, burning sun and went to Barnes and nobles to read some stuff. I read Scientific American and Scientific American Mind today and read up on two interesting articles: One about BC-I another about Smart Drugs What I’m getting at here is the technological and pharmaceutical revolutions that are going to be active within this century. As people become more intelligent, they are going to want to become intelligent at a faster pace. Smart drugs, also known as nootropes, can supposedly bring up the cognitive thinking abilities of people. How well they work... I don't know. In scientific mind they presented some basic dru…

Is there any "normal" physiological reason for one of the the testicles to be slightly larger than the other? Are there also any medical causes that could explain the same condition?

What are the consequences of having an electrical neuromuscular junction, there must be reasons why the nmj is chemical?

Hey! I have a son who developed a seizure disorder about 3 weeks after birth. I'm happy to say he had his last one over two years ago & is about to undergo his last EEG to reassure the neurologist that he has "out-grown" the seizures & we can start weening him off of his meds. I'm just wondering if an infant can "rewire" their brain around a problem or fix the problem why can't we stimulate this action in other humans? Is it the the constant developement of the childs brain that enables him to do this? If so then why does this differ from ,say, adults learning new things? I'm guessing it may have something to do with where the problem is & possibly how develop…

Bottom line: phenomenological objects generated in the cerebral cortex get "peer reviewed" by other parts of the cortex, and that's how their validity is ascertained. http://arxiv.org/abs/cs.CY/0506024

hello thinking more and more that the computer is beginning to mimic the structure of the human brain. at first computers used a single processor for handling all processing aspects. now however multi processors are used, with different ones handling sound and video, much as the brain uses diferent areas to handle different functions. to that end i believe that sleep might serve for humans what a ram sort does for computers. it apears the brain has a limited amount of ram (random acess memory), shuffling information in and out of rom (read only memory) as needed. however at some point the mind can not hold or process the information shuffling amoungst the form…

My close friend suffers from migraines and occasionally she will lose control of her senses as a result(i.e. hearing things that aren't there) and will have her blood vessels explode and constrict, causing pain. She gets the more mild type of migrains too, but this subtype really has me baffled mainly because I've never heard of it before. Her doctor said it's "rare but not unheard of", so maybe someone around here knows about it? Thanks.

Are there any negative effects from drinking a mix of red bull and alcohol. I have a couple friends who want to mix the two. I remember learning a few years back that mixing a stimulant and a depressant is unhealthy, however i forget the details. Is this true.

This may seem like a really odd question, but I need to know the answer for a paper I’m writing. My question is also hard to articulate so I hope no one minds if I make it rather lengthy. I’m wondering about how signals in the sensory cortexes of the brain, and particularly in the visual cortex, are relayed to the cognitive centers. Specifically, I’m wondering if the linear processing of information (from simple feature detectors to more complex features to abstract features to concepts and so on) is completely serial or is there some parallel processing, and if there is, how much? For example, the diagram below shows the a simplified model of how information is proce…

an observation I`ve not only made myself but others too. Why is it that when we consume alcohol at a rate, our Cigarette consumption rises too? I`ve seen a 10 a day smoker get through 20 cigs in an evening when on the "pop" this can almost double when on spirits! to the point of chain smoking! what causes this? does the smoke enhance the drink? does the body know that the drink is doing harm and Uses something in the cigs to limit it (a Chemical reaction)? is it a Brain thing? I`ve also noticed that a certain level of intoxication (one I`de consider extreme) that cig smoke makes the situation considerably worse and often ends up in a colapse or... how shal…

Hi, There seems to be a general principle that if a drug binds naturally to a neural receptor, then there must be indigenous neurotransmitters for that receptor. Some have argued that this means the drug can't be all that harmful. I'm just wondering how much truth there is to that. I mean, sure there might be a neurotransmitter that's naturally produced by the body which binds to those receptors, but the use of the drug brings on completely different effects, subjectively and behaviorally. In other words, the drug is mimicking the indigenous neurotransmitter in a very unnatural way or under very unnatural conditions. Take cannabis, for example. THC binds to recept…

What part(s) of the brain are involved in math skills?

I've heard of the binding problem in the neuroscience: how seperate mental functions carried out by separate brain parts come together to form perceptions of something "whole". They say there is no part of the brain that all the electric signals being processed converge to - that is, no part that seems to integrate all this information so that we can have perceptions of whole things. I was wondering how far reaching the bind problem is considered to be. I mean, for example, I know that it means to say that there is no central part of the brain where ALL information converges to for integration, but what about less wholistic things? For example, when I look at an apple, I …
