Heart Rate Monitoring on the Cheap

Dear Hive Mind, My friend (a graduate student in psychology) wants to collect physiological measures for her dissertation. However, she doesn't have much money with which to do so. What is the cheapest way for her to accurately record the heart rate of some undergraduates? How much more will it cost her to be able to export the data to a computer? Thanks 10^6, zscore

Book recommendations for brain / arousal / EEG / neurotransmitters / meds?

I would like to get some book recommendations on the following topic: the connection between brain arousal states (am I using that term correctly?)

Best Anatomy/Physiology Videos on Youtube?

I have to learn anatomy and physiology on my own in a very condensed period of time. I find that I learn best by watching a lecturer or fantastic video. Do you have any recommendations for fantastic lecture series on YouTube detailing the anatomy and physiology of various organ systems?

What size VFFs would accommodate the greatest number of students?

The high school level anatomy and physiology class I teach is going to do a unit on running and movement. Help me figure out what size VFF's to request from a generous donor to accommodate as many of my current and future high school students possible. If you wear VFF's, I'd appreciate you looking inside and giving me your traditional shoe size (US) and VFF sizes (I think we're getting KSO's). If you have any other great foot physiology sites or books (not mentioned here or here), I'd appreciate that info, too. I just wiped out my local library. [more inside]

Nervous and cardiovascular systems detail for high school A&P?

Hello! I am leading an Anatomy & Physiology study group for homeschooled teens. The aim is to work at the advanced high school level, but I'm using a college textbook (Thibodeau & Patton), as the illustrations and charts are more useful, and it might come in handy for them for later reference. But I'm not sure how deep to delve. [more inside]

Why don't adults enjoy dizziness?

Why don't adults enjoy dizziness like kids do? When I was a kid I remember thinking adults were boring for not enjoying the feeling of dizziness, and I vowed to always enjoy it :) Now as an adult, I can't stand it, and feel like throwing up. It seems most adults (if not all) feel the same way. Why is that?

Catfilter: If I spay my cat while she's in heat, will she continue to yowl for the rest of her life?

I thought my cat had just _finished_ her first heat and made a vet appointment to have her spayed tomorrow. Well, guess who started yowling and moving her tail sideways to display feline private parts?! Should I keep tomorrow's appointment and have her spayed _during_ her heat, or should I wait?

Can anyone recommend a good graduate school for Nutrition Major?

Hi, I only have 1 1/2 years till I'm completely done my undergraduate nutrition degree in Canada. I've already established that I want to pursue a masters, however, the only school I have been checking online is Columbia's Department of Nutrition because it is the only school I can think of which offers a decent program. Is it true? If not, does anyone have any good suggestions (NA, Europe, Asia)? [more inside]

Books on DVDs on exercise as body-exploration?

Are there any good DVDs or books that teach you exercise as a way of understanding and having fun with your body? I'm looking for a system whose focus is not primarily on losing weight or being healthy but on learning about your body and being able to do cool things with it you couldn't do before (gain better balance, stand on your head, improve your ability to drag furniture even), but that would also incidentally give you an excellent workout. Ideas?

I'm bleeding from my hands. So why can't I hear?

Hypotension/hypovolemia as a low-pass filter: I got cut, I went into shock, and then everything started sounding funny. I'd guess it was a 40 dB (±10) rolloff, which began near 200 Hz (±50) and left me with nothing above 1kHz. How in the world? Story, discussion of numeric estimates, off-the-cuff physiological speculations, etc... [more inside]

The Underwater Shiver-- What Causes It?

So I'm still trying to pinpoint this one (I keep forgetting to ask it, and Google turns up nothing)-- when one lies down in a bathtub, faceup, and submerges at least their entire ears, they shiver (it's more kind of an uncontrollable, brief spasm of the upper body and doesn't FEEL like shivering, but looks like it). It isn't related to the water temperature, as far as I can tell, and DOESN'T happen when facedown or swimming, etc. Or do other people not have this happen? Do you? I get it every single time, without fail, and have since I can remember. My mom knows exactly what I'm talking about, but my dad insists we're both crazy. Is this just one of those odd reflex reactions like coughing when you have something in your ear or sneezing when you get in the sun? (I also do that one-- always funny to explain to people :) ) Any idea what causes this, though?

Is stuttering more common in some languages than others?

Is stuttering more common in some languages than in others? If singing is supposed to suppress it (true?), does that mean tonal languages (e.g. Chinese) do not suffer the phenom? Indeed, are there any languages in which it does not appear at all? If so, any theories why?

physiology of sighing

What's the connection between a thought of regret, or of resignation to a negative situation, that causes humans to involuntarily fill their lungs and exhale slowly? Is such sighing learned behavior? Does every culture sigh for this reason? Animals sigh. When my dog sighs, is she laying there regretting she didn't roll in that dead skunk when she had the chance?
