Anatomy, Physiology and Neuroscience

I read a theory by G. Tononi on how he uses mathematics to quantify conscious experience. We know that the brain is responsible for consciousness but how the physical brain gives rise to the conciousness is a bit of a challenge. http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1003588 It has strong ties to the theory that consciousness arises from the integration and differentiation of information in the brain. It's a fascinating but heavy read.

Two links: 1) http://en.wikipedia.org/wiki/Triune_brain 2) http://www.whatonearthishappening.com/part-1-the-solution/65-the-triune-brain Another link that may not be so relevant: 3) http://mybrainnotes.com/memory-brain-stress.html Pseudoscience or still a credible model? From what I recall of my neuroscience, phil, and psych classes, the brain really focuses a lot on learning and conditioning, which then turns over into neural changes. I think the triune brain theory is interesting. However, MRIs give a different story in relation to the theory: MRI technology and research developed well beyond the theory. According to Wikipedia, Ok, so …

Hi everyone Few minutes ago, I experienced a 'wave' of shocks in my head. I have experienced these shocks before. I woke up at 10.45 a.m. Now it's 1.20 a.m. Normally, I go to sleep at 10.00 p.m. and wake up at 5.00 a.m. (thought it might be important, my hours of sleep) They start all of a sudden, and last for like, 1 minute or so, with breaks inbetween them (e.g. 5 shocks, brake of 10 seconds, 3 shocks, ...) I've now been lying on my side, my laptop in front of me (positioned on its side too, just for comfort) and now the shocks began. Can't really explain what they are, but it's like all muscles in my head or whatever (not facial muscles) contract, I hear a h…

When I close my eyes I do not see pitch black. In fact for as long as I can remember the darkness has been bright and noisy. I've also always felt planes and other far away sounds. To me sound has a mass to it. It's as if I can actually see, hear, feel physically and emotional, all at the same time. It's seems all of my senses are completely connected in my mind's eye. If I concentrate I can project. Not only that but if I focus my attention on any muscle I can move it and control it perfectly. When I say muscle I mean every muscle, even my heartbeat! I can point my ears in any direction, control my nostrils completely and individually, raise my hair. It seems I can also …

Quick question: Which muscles help you get up from sleep? I think some of the anterior abdominal wall muscles (or may be the posterior ones?) thanks for your help

Does anybody tried to read something on the question of Mind Control? The only book came to my hands with objective data is by Jose Delgado. Some years ago as a medical student I've been trying to study hypnosis but it seems to be non scientific anymore. Id like to find some new literature on the question of brainwashing And here is a brief review of the book Physical Mind control links removed

As a Neuroscientists, I also consider myself a Physicists. You have different sides of Neuroscience, you have the Neuroanatomical side of it. Where research is done on how different parts of the brain works. You have the cellular side of it which neurons are studied as a biological system or units, in Neurobiology. You have the chemical side of it in Neurochemistry and Neuropharmacology. You also have the mixture of biology and philosophical side to it, where Neuroscience meets Philosophy, were one talks about how we perceives the world and how it relates to our minds and brains. However, you also have the side.. best defined by physical laws and biophysics of the neu…

(Context) I'm a medical student in the UK about to apply for an intercalated year of academic research before my clinical training starts. Anyway, I was considering a project based on the changes to mitochondria during exercise. There are papers that have been published showing certain genes in the nuclear genome are upregulated during exercise and aerobic training will lead to an increased mitochondrial count in each cell. I am wondering if there is any published research as to whether or not there is an increase in transcription in the mitochondrial genome in response to exercise. It would make sense that as well as increasing the number of mitochondria in a muscle cel…

Hey there, I need some help identifying 2 scapulae. All we have been told is that they are in some way related (although this relation could be as simple as both bones being scapulas). The first one looks a lot like a humans scapula, so we're suspecting it is a biped, more than likely a primate. The second one is a lot narrower, has a very large spine, barely any coracoid process and seems to have a deep glenoid cavity. Any help would be greatly appreciated. I'll upload pictures of them, if the image labels don't get displayed, the more pale bone is the one I am referring to as bone 1. Thanks

I am confused that there is a lack of clear papers from my preliminary search that deal with the calculation of the efficiency of working human or animal muscle. This is important not only from the viewpoint of the effectiveness of exercise regimes but also the efficiency of quadripedal gait compared to bipedal gait. Any references to papers or thoughts welcomed

hello friends, im trying to understand the very basics related to the function of temporal lobe of the human brain. more specifically i would like to understand the parts related to hearing and speech recognition like wernicke's and breca's area. i know about the functions of these parts but i cant find information regarding how these parts work or how they process information. what kind of receptors and neurotransmitters are involved? what causes excitation and de-excitation of neurons in this are? which harmones effect the function of these parts? i am unable to find this information through google thats why im here. plz reefer me some book or a link of any website wher…

Any help will be greatly appreciated...

Is it possible for the ankle to dorsiflex and the foot to plantar flex (e.g: in the heel-contact stage of gait). My lecturer suggests it is possible but I do not understand how? Thanks

(Context: I have no science background and am asking this out of curiosity. I am a fiction writer and I'd like to see if what I am thinking of has any scientific basis.) If an external limiter is put on a section of the body's growth, what will happen to that section? More specifically, I'm wondering what would happen if someone were to put a large keyring around their ankle at, say, age eight, and then for whatever reason left it there. What would happen when the body started naturally growing to that limit (that is, the size of the ankle reached the size of the key ring and by assumption of 'normal' human growth would try to KEEP growing)? Would there be pain …

I know that severe malnourishment in childhood can negatively affect height for example, but can diet have influence on it as well? Teke Asia for example - the tallest of all East Asians are Northern Chinese, followed by Koreans and Japanese, with South Chinese and peoples of Southeast Asia being generally the shortest. I know that such disparity can be explained by genetic differences but diet differences have been suggested as well - more precisely, higher intake of meat and dairy products in the north as compared to more vegetable based died in the south. Is there any truth in this? I wonder. And East Asians in general are smaller than Europeans. For example, …

Hello all! I have a question about bone grafting.I have bone wasting in my leg,and there is a "chunk" of bone missing,which both functionally and aesthetically is bothering me really.I would need an implant/graft in that zone.I googled this but only dental bone implants/grafting came up,nothing about grafting in limbs or other zones.Can someone help me with this matter,is this process available on limbs like in dentistry?How can I enter in contact with a surgeon/clinic who specialize in this? I would appreciate any kind of input and help.Thanks guys Cheers

Among all human organs, which are less prone to illnesses, failure, cancers; found in better condition than others at old age death, or rarely give/harbor health problems ? To what would you attribute such endurance ?

Can anyone help me to caption this section or tell me where I can find this one already captioned? Thank you.

hello,does anyone have microchip scanner for human implants

Man living with no brain puzzles scientists 25.07.2007 The following case provides evidence that the human brain can adapt itself to a pathology that occurred earlier. Despite the pathology, the sufferer’s neurological and physical development was not severely hampered. He was able to lead a life that can be considered normal. French doctors are still racking their brains over the case of a patient who is said to live a normal life despite the fact that his brain is almost completely absent, reports RIA Novosti news agency. Quoting an article published by The Lancet, the agency says that the 44-year-old French civil servant, a married man and a father of two, was…

Are false memories a common occurrence and how often do they affect people? Is it possible for someone's entire life, or a good portion of it, to be a false memory? Have there been cases of this ever happening? Thanks.

At the risk of getting a verbal spanking about It, what is the lazy mans easy way to increasing lean muscle mass? I've been visiting alot of weight training forums and to put it in a nutshell the basic process of growth comes down to eating huge amounts of food, training with ever increasing weight loads and adequate rest. The weight loss AFTER the muscle gain is what's troubling me, the ever increasing weight loads are just a personal challenge and to lift more and more is after all the name of the game. Aside from steroids is there a way to trick the body into an anabolic state without consuming the vast amount of calories these sites recommend?. Could a per…

My muscles are made of stone, my side split maxes out at 45 degrees... I'm one of the most inflexible organisms on Earth. So I've embarked on a quest in becoming supple-bodied, but, as the title asks, is a warm up essential? I'm asking this because my locality gets very cold at this time of the year and takes a century to get body temp rising; this time is the biggest 'put-off' for me wanting to stretch. So was just curious to know the science behind getting flexible generally, and significance of the warm up prior to stretching. Thanks, Adshed.

I have been thinking of artificial intelligence and trying to find my own way around the research. I want to first get associated with feeling and such and see where that leads me. So, it is obvious that we are capable of feeling touch. We are able to touch and the particular part of the body touched feels that touch. However, in many cases when a person loses an arm they can still feel itching in that particular area, which implies that the brain has much responsibility over feeling rather than the nerves itself, though the nerves themselves play a big role in it. My question is how is the brain capable of making us aware of the location of the touch? I know it d…

I was thinking back to the ken ham and Bill Nye debate, when where does consciousness come up. Nye completley dropped the ball, in my opinion. How could he say we don't know? If you ask me, consciousness comes from the brain. It is the projected processing from all of our senses and emotions tied together. How could he have just said "I don't know, it's a mystery."
