When I here certain things i get overly annoyed at them. Like i have to basically ignore my math teacher to not become infuriated at her using the word "okay?" before and after every sentence. I usually only get annoyed by habits that people have like switching your foot up and down. A person could have a habit that they do a thousand times and i wouldn't get annoyed but once I notice it I began to notice it more and more. So only people I tend to spend a lot of time with begin to annoy me. The funny thing is the over use of the word okay is the thing that annoys me most because i have heard it overused by every math teacher I have ever had. Is this AS? because I'm not an…

Right now, I'm doing research in the field of microbiology. I've been doing this over two years now, but recently, an opportunity came up where I might be able to join a different lab. the website: http://bme.sunysb.edu/people/lstrey/home.htm I'm happy where I am now, but I've been doing it for a while, and I don't really have many experiences in other fields of biology. I think the work that the cognition lab is doing is very interesting, and completely novel for me. I'm going to have a meeting with the professor on Monday or tuesday. I would feel bad leaving my old lab, because I know the people really well. But, this would be the best time for me…

I first noticed this effect in my eyes while lying in the sun. With my eyes closed of course the eyelids appear bright red and all sorts of unfocused colour blobs seem to float about as the eyes recover from looking at brightly lit objects before closing. It's not these lights I mean. It was after five to ten minutes and letting myself relax, I began to notice something like an array of lights descending across the inside of my eyelids. The effect lasted approx 2 seconds. I only took notice of it because it repeated regularly. It pulsed every six seconds for two seconds. I have been able to notice the same effect at repeated times and even managed to experience …

I have been trying to burn off some extra baggage ive accumulated and its got me thinking about how exactly your body burns away fat. Specifically, where the fat comes from first. for example, if i were to do a lot of ab exercises i know i would develope stronger, more defined abs, but would the fat in that area be burned away first, or does it follow some other order? if im running, will my leg fat be burned before my body moves on to stomache fat, or will it be pretty evenly spread, or something entirely different?

So, I'm not a fit person. In nice terms, I'd call myself an overweight-bordering-on-obese lazy slug. But, the point of the matter is that I'm working to change that. I go to the gym in the morning, and I'm working on a M-W-F schedule, eventually I'll probably mix a fourth day in. My question is a simple one. Because of my overweight and lazy nature, going to the gym (when I actually work out a decent bit) causes muscle pains. No pain, no gain, right? The question then becomes, if I am still in pain 48 hours later when I go to the gym again, what is my best option? Is it to seek medical help because I should have recovered, to wait until I do recover to go again, t…

Simple question. Why are human noses so oily compared with the rest of the skin? Wild and uninformed speculation welcome as always.

I read the questions about vaginal swelling on your web site and talked to my doctor about my own swelling. The doctor did not examine me and basically said it was varicose veins. I can't tell you how much the vaginal swelling hurts. It also bleeds a little. It is limited to one side of my vagina. Do have any relief ideas? This is killing me! I am going to make that doctor look at this swelling when I go back. Why doesn't anyone talk about "cheeseburger crotch"?

So I've been recently reading This is Your Brain on Music. Just a few minutes ago I've had an ear-ringing experience (not the first, probably not the last) I work in an office connected to a machine shop. So ambient noise is that of machinery, a/c, people chatting, computers... you get the idea. Anyhow, I'm sitting here typing away and I get the ringing. In my right ear the ambient noise drops to about 1/2 it's current level and a tone of around 1kHz takes over. This is in the right ear only, and it feels a like there is a little more pressure in there. This goes on for about 15 seconds, then the pressure returns to normal, the frequency increases until I can't h…

Double vision Hi guys, hope you can help in some way here. A friend of mine all of a sudden started having double vision. He though it will go but then started having very high temperatures and was admitted to hospital. They did not know what it was so they ran a blood test then a lumber puncture. He was still having high temperature and started shivering! Was a bit scary! After being on heavy anti viral his temperature started stabilising. He couldn’t eat properly and he threw up most of the time. After the Anti viral, he started feeling a bit better. So they have sent him home but he is still on anti viral pills (can’t remember the name). Anyway…

Are brain dead and coma the same? When a person is dclared dead is it when both brain and haert stops working? How long a person can be i n coma stage? Thanks

What makes a neural network programmable (actual neurons, not the computer simulation of them)? I've learnt that neurons don't physically move their dendritic connections from one cell to another (not in the adult brain, at least), so what changes when we talk about a neural network being "programmed"?

From what I understand, when the brain develops, neurons grow in random directions and form random connections with each other. The more functional or effective wiring schemes are then selected for based on whether or not they help the organism accomplish certain tasks (such as recognizing food, getting past barriers, satisfying urges, etc.) What is the feedback mechanism that lets these neural circuits know that they're useful and should be preserved or improved upon?

What part of the brain is responsible for conditioning the body to overcome a knee-jerk response such as pain. You can get people who find pleasure out of pain, is this something you're born with, or is there a specific part of the brain, that can alter how such a response is processed ?

This thought just popped into my head randomly... Why can most people cross their eyes but not move them otherwise independently? Surely if we can make the muscles cross our eyes, we can work out how to go the opposite direction.

Hi, I want a vedio showing how lumber puncture is performed. I've a presentation after 2 weeks and I'd like to support it by this video instead of showing pictures. I didn't find any thing in Google Would you help me.....

Do they enter the muscle through the origin and spread from there, or maybe somewhere near the musculotendinous junction?

This struck me whilst eating peas this night. Is there anything special that chlorophyll does or that happens to chlorophyll once ingested? I gather it doesn't make sugar.

Hello, I have troubles in bilirubin degradation and deffirent types of jaundice. plz, help me by a useful website ,figures, or discussion I realy want to understand this subject from a physiology point of view and thanks in advance

I`ve just had a quick read about histamines in an old book, and from what I can tell they Don`t seem to of much good to us. 1) they open up blood vessels when tissue is injured. Surely that`s the worst thing you want to happen, restricting them, and thus Blood flow would be far more beneficial I would have thought. and 2) they also stimulate Hydrochloric acid production in the stomach when stressed. now what evolutionary purpose can that possibly serve?

This is something which has long intrigued and fascinated me. Black people seem to age very slowly and white people seem to age very rapidly. What causes this? Is it something within muscle density?

How do they sense the velocity of the muscle stretch, and how does that produce action potentials? I'm trying to figure out how the patellar reflex works in detail for this lab report. I'm not sure if I need that in my report, but I'm very curious about it, and wikipedia sort of glosses over it. "This change in length of the spindle is transduced (transformed into electric membrane potentials) by two types of sensory afferents," - How does this happen?

This topic will be about the similarities and differences between the anatomy of chicken or avian bones and human bones. This could be anything like structure, composition, physiology, etc. whatever may be applicable to comparing the two type of bones. Anything you can think of, please reply. Thank you for your time.

I am a neuroscience student. After blocking NMDAR, why EPSCs can still be observed at the synapses? Is the EPSC due to the activation of AMPARs, as most of the synapses in brain are calcium impermeable AMPARs, so the EPSCs is due to the influx of Na+ ion?

Emotions are our master and we are humble servants to them. All things that we do can be explained through our endeavor to reach a certain emotion or to avoid another. Emotion is that very mechanism that makes the human species to work in such way as it appears. What is emotion? An emotion is developed and refined stage of instinct. Instincts make a spider to weave a web, to prey insects for food and to mate. Do mammals and birds live by their instincts or by their emotions, that I do not know. I've only heard that only rabbits and humans take pleasure from sex. In any case, at least human species has developed a more complex motivator: emotion. Thus humans do and…
