David Attenborough: Carnivorous Plants

rembar says...

Seph, it isn't quite so Freudian as all that, but still a rather interesting story. From Sarracenia.com:
"The true reason that Venus is part of this plant's name due to the dirty minds of the kooky naturalists and nuserymen (such as John & William Bartram, Peter Collinson, William Darlington, Arthur Dobbs, John Ellis, and Daniel Solander). When they looked at the plant, they saw in its amazing behavior and attractive form (two red, glistening lobes, surrounded by hairs, sensitive to the touch), something that reminded them of female genitalia of their own species. Indeed!

Amongst themselves, this cabal of learned perverts referred to the plant as a "tipitiwitchet" (or "Tippity Twitchet"). It was subsequently assumed by historians that this was a Native American term, but linguistic experts have eliminated that as a possibility.

Tipitiwitchet, it appears, was a naughty euphemism of their own devising. I like to imagine a few of them coining the term one night as they were slamming down beers in a pub or in a sumptuous study. I'm guessing that the originator of the term was probably John Bartram. For while you might expect a scientist to express wonder or astonishment upon seeing the plant, Bartram wrote to Collinson on 29 August 1762 that "my little tipitiwitchet sensitive stimulates laughter in all ye beholders"."

" wow! great sift. the frontal lobes! "

hey man, uhhhh, alcohol does give the hind brain a day at the races, dude, that part is pretty easy-peasy.....this should tell anyone that moderation, in combination with knowing ones own physiology and giving a fuck about others, should be your gauge....that and society's regulations.....

One of the most interesting parts is in the later half of 2c where his wife contrasts the differences in episodic vs semantic memory.

Good post antiuser, you might also like "The Man Who Slept for 19 Years"(not posted online) about a car accident victim, additionally, Mindshock's "Sex on the Brain" episode http://www.youtube.com/watch?v=GbFkz1_C5SU The first one is amnesic(still thinks it's 1984) both exemplify the the effects of temporal lobe damage to emotional constraint.

Some the most interesting videos I've seen was over at Princeton's webmedia site:

Like Michael S. Gazzaniga, Dartmouth University: "Personal Identity, Neuroethics and the Human Brain"

This was, by far, one of my favorites. He cites some fascinating studies.

Jeremy Fisher- "Cigarette"

Farhad2000 says...

"A prune-size bit of tissue tucked under the frontal lobes, it controls gut feelings and habits; it's what drives a recovering smoker to yearn for the feel and taste of cigarettes. The "reward circuitry," a network of neurons at the core of the brain, also plays a role. Nicotine boosts the brain's levels of dopamine, the "feel good" neurotransmitter. Another, as yet unknown, chemical in tobacco smoke acts like an antidepressant, blocking an enzyme that breaks down dopamine. So smokers get a double dose of the stuff—and about half end up addicted, essentially, to their own brain chemicals.

Remove the nicotine, though, and the body can't maintain the high dopamine levels on its own. In the brain of a smoker who's trying to quit, receptors start "screaming," says Dr. Norman Edelman of the American Lung Association, "crying out to be satisfied." Smokers often say a cigarette calms them, but by the time they're addicted, the nicotine rush simply halts the first symptoms of withdrawal. "The addiction is why you're nervous in the first place," says Edelman. Longtime smokers also have to end a behavior that's "entrenched in their daily lives," says Corinne Husten, head of the CDC's Office of Smoking and Health. Add in the stresses of, say, running for president, and it's all too easy to slip.

It may seem drastic to call a smoker an "addict" but, says Chris Cartter, who runs QuitNet, the world's largest quit-smoking program, "a lot of doctors view this as on par with overcoming a heroin addiction." The withdrawal isn't as ugly, but it's not pretty, either: shortly after quitting, the typical longtime smoker becomes cranky, has trouble sleeping and making decisions, and gains weight. Usually, the first weeks are the worst, but for some people the symptoms can drag on for a year or more.

That's assuming, however, that the smoker is taking the cold-turkey approach, which there's little reason to do these days. Nicotine gum, approved in 1984, is the oldest anti-smoking aid. (Obama chews it throughout the day.) It's about as effective as the newer patches, inhalers and nasal sprays, all of which placate those screaming receptors without being addictive themselves. Other options include Zyban, which is also marketed as an antidepressant, and Chantix, introduced last year, which eases withdrawal and blocks nicotine's effects."
