Why does my daughter (5) who had a tumor resection on the right side of the brain right past her optic nerve see certain people and instantly get scared and throw up? I am wondering if the where they went into her brain has caused her to mix up imagination from reality????

I'm working on some medical entries for a dictionary and I'm stuck on something called ischoanal fossa and another thing called pubic recess of ischoanal fossa (recessus pubicus in latin). It would be absolutely awesome if someone could post a diagram/picture/etc with this pubic recess marked. Its supposed to be a frontal part of the fossa but I just can't find it anywhere. I also can't find anything about its function.

I feel as if most people would agree we have the following senses: sight, smell, taste, touch, hearing. While sleeping it could be said that we experience no sensation for example. Currently I would assume you're on your computing device reading seeing this post. The question is how do we use science to increase the desirability of our sensations? I like looking at art, putting on cologne, eating nice food, getting massages and listening to music but sometimes for no discernible reason my sensations go into overdrive and everything seems perfect. I'm trying to figure out how to improve the desirability and enjoy-ability of all of our sensations.

How effect is NLP (neuro-linguistic programming) a tool in psychotherapy ? Please advise.

What's makes neurons special for Herpesvirus to rest latently in them? Is it because neurons don't divide?

Please take a look at this figure: This illustration is actually a part of the "figure 8.2" in Grey's anatomy of students. As you can see, it states that the maxillary nerve passes through the pterygopalatine fossa. The problem is maxillary nerve, as I figured, first passes the cranial cavity through the "Foramen Rotundum" and the anterior opening of this foramen is illustrated in the figure below: So that's clearly above the site which is stated in the grey's illustration. If we accept that, then we have this: I wonder if It's still in the pterygopalatine fossa. I'm also eager to know whether the grey's illustration is incorrect or I'm in a state of …

How would I know what muscles contract and which ones relax during each phase of a particular movement such as walking? I mean for the arms and legs that is pretty easy. I can just feel my own muscle and see if it feels smaller or bigger during each phase to know whether it is contracting or relaxing. However the glutei and abs are also involved in walking. In particular the glutei in the forward movement of the leg and the abs for stability. For me it is not as easy to feel the muscle to know whether it is contracting or relaxing when it comes to the glutei or abs, especially the abs. So how would I know whether the glutei and abs are contracting or relaxing during each …

Hello Everyone, Im working on a project where Im trying to extract DNA from recently fixed fish specimens stored in Formalin. The problem is that formalin degrades DNA. I was wondering if anyone here might be able to interject with what might be the least penetrable (most dense) organ in the human body (which would likely be the same for fish), one that would potentially take the longest to be penetrated by the formalin. Maybe there is an organ thats not so dense, but would some how keep the formalin from penetrating the interior? Basically something that is in-penetrable by liquid on the outside???... Any help or even suggestions would be greatly appreciated. Bes…

Crossman and Neary write that... "Destruction of the splenium of the corpus callosum by stroke or tumour leads to the posterior disconnection syndrome of alexia without agraphia. Such individuals speak and write without difficulty but cannot understand written material (alexia). Disconnection of visual processing in the right hemisphere from the verbal processing of the dominant left hemisphere is thought to explain the syndrome" I thought that visual processing was not dominant to one hemisphere and that if it was it was dominant to the left hemisphere anyway because more people have stronger left eyes. I am aware that language processing occurs mainly in the left hemis…

I read an article that stated that the legendary composer Ludwig Von Beethoven had cardiac arrhythmias and this came across in his compositions. (in terms of creativity...) Is there some causative link between the two ? Please opine.

In the words of Deepak Chopra "Meditation makes the entire nervous system go into a field of coherence".Would this be a realistic assertion in the light of our current knowledge about the sympathetic and parasympathetic nervous system ? Would then this field have quantum field properties?

Ok im trying to work out how the anterior fibres of the gluteus medius internally rotate the femur. The problem is with every diagram I look at its shows a different shaped gluteus medius with fibres going in different directions, so there must be a lot of faulty information out there and I need some accurate images. The best picture I could find was of an actual persons gluteus medius and the only problem with that is it is different from every other picture/diagram ive seen of the gluteus medius, especially the anterior fibers which is what I need to look at to understand how internal rotation works. They were all curved and attached to the front of the trochant…

Hello, I've got questions about caffeine tolerance. Is there a minimum amount that one can take per day without tolerance building up? Say, 50mg per day? Or does tolerance start to build up no matter how little one takes?

A neurological pathway has gone awry, so disrupt that pathway. It seemed simple enough, so I did a search. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1629706/ It was performed as early as the 60s, and this rather breif summary describes optimistic results. I'm tempted to call it a cure! What happened? Most articles on treating sex offenders only mention therapy and libido-reducing drugs, but both of these involve life-long regimes that subjects might undermine or quit. And today we have a reversable intervention called deep brain stimulation. http://link.springer.com/chapter/10.1007/978-3-319-01144-8_4 https://en.wikipedia.org/wiki/Deep_brain_stimulation

Hello everyone First of all, Merry Christmas. Closing a Na-gate causes hyperpolarization. Why won't Goldman's formula tell us this? Goldman tells us that you get hyperpolarization if the ratio [math]\frac{p_K[K^+]_i+p_{Na}[Na^+]_i}{p_K[K^+]_e+p_{Na}[Na^+]_e}[/math] is getting bigger and bigger. Closing the sodium channels only has an effect on the permeability of sodium, so either the internal concentration of sodium must raise, or either the external concentration must lower. (Consider pK, [K+]i and [K+]e constant. So the potential would now only rely on pNa, [Na]i and [Na]e.) However, closing a sodium channel causes the external sodiu…

Hi guys My professor in physiology told us that if the permeability for Na+ and K+ in a neuron would be equal, the cell would depolarize to a resting membrane potential difference of about -10 mV. However, applying Goldman's equation and concentrations intracellular K+ of 139 mM, intracellular Na+ of 12 mM, extracellular K+ of 4 mM and extracellular Na+ of 145 mM gives us: [math]-60\cdot\log{\frac{a\cdot 139 + a\cdot 12}{a\cdot 4 + a\cdot 145}}\approx -0.347[/math] mV. (The a is to indicate that the permeability for both K+ and Na+ is the same) Quite a big difference, over a factor of 30 in difference. My professor told me he used the average of the …

When you sleep you can dream and see pictures playing in your head. However your eyes are shut. Now there has been the discussion brought up before can blind people dream if they have no concept of what anything looks like to begin with? So I had an idea could you make blind people see if you hooked something up to their head that would rely pictures straight to their brain? Isnt that kind of what we do now with our eyes? We are simply relying information and our brain is processing what we see. You can see when your eyes are closed such as dreams too.

How do memories work? how are we able to imagine, think, learn. What is the substance of thought?

I am writing a novel and am trying to come up with a theoretically sound way for mankind be overrun with sometime of viral, bacterial, fungal, etc. evolution which our bodies would be completely incapable of battling without a Homo Sapiens evolution as well. This condition, attack on our species, needs to specifically attack the brain and be able to cause a variety of conditions such as Alzheimer’s, Cerebral Palsy, Multiple Sclerosis, Parkinson’s, Huntington’s, Pick’s disease, ALS, Dementia, etc. Any creative and knowledgeable input would be greatly appreciated. Thank you.

Hi all, My name's Juan Antonio and I'm studing the memory neuronal system in rat's brain. I'm searching a anterograde fluorescent tracer that I could use without antibodies; autofluorescence. Could you help me? Juan Antonio.

My understanding is that medial rotation of the upper arm , specifically, when the humerus is parallel to the body, is the action that best isolates* the pectoralis major muscles (as opposed to flexion or adduction). Could someone please confirm or refute this. Thank you. *By 'isolation' I mean that the movement engages the smallest number of other muscle groups.

Hi all. I was reading about the causes of pulmonary oedemas when the lungs are under hypoxic conditions, and I just want to check my understanding. From what I gather, hypoxic pulmonary vasoconstriction occurs in regions of the lung that are not receiving much oxygen (though I'm not sure whether the blood pressure in these pulmonary capillaries increases or decreases). When the entire lung is oxygen deficient, all of the pulmonary capillaries constrict and this leads to pressure build up in the pulmonary artery because blood doesn't move so easily through the capillaries and it takes longer to drain from the artery. However, I also read that pre-capillary sphincters cont…

If someone has a bigger skull they then have the potential to have a bigger brain and i would like to know how important this is for genius iq. I saw a video on youtube about this guy called Christopher Langan who claims to have the highest iq in America, he also mentions he has a very large head (6 standard deviations above normal) and speculates this could be related to his high iq. It made me wonder is it required to have a large head size to be a genius or is the way the brain wired more important? Are there any examples of famous genius and their head / brain sizes?

I woke up the other day with an extreme lethargy and down mood, with no known reason behind it. I also have an extreme need for pomegranate and cocoa nibs, meaning I have to shove piles of them, together, in my mouth, all day long. When I do I feel great. When I don't, the lethargy starts coming back. I've never eaten them together like this before, though I do tend to eat a little of each every day. No other foods even make a dent in this lethargy and down feeling. This is day 3 of this odd bodily behavior. Any theories?
