And the breakthrough it led to

(NEWSER) - When Thomas Harvey performed Albert Einstein's autopsy, he removed his brain, which was standard procedure. But what he did next wasn't standard at all: He put the brain in a jar of formaldehyde and made off with it. NPR relates the strange tale in a segment this morning. Harvey said he was driven by a sense of scientific duty, and through the years would freely distribute bits of the brain to leading neuroanatomists. More»

New study discovers why some people may take financial risks

(NEWSER) - Why are some stock traders and gamblers so willing to take financial risks? A new study shares a possible answer: Scientists found that people with higher levels of the neurotransmitter norepinephrine in a critical part of the brain related to sensory and reward systems are less sensitive to the pain of financial loss.

Doctors pinpoint the so-called 'nocebo' effect

(NEWSER) - Worried that it's unhealthy to be glued to the Internet, surfing through stories? That anxiety alone could cause health problems—and doctors are now uncovering the neurological roots of this so-called "nocebo" effect, according to an award-winning essay by Penny Sarchet in the Guardian . The opposite of the "placebo" effect, the "nocebo" effect occurs when people believe that an illness or side-effect is real. Turns out it's all in the mind, and scientists can pinpoint it. More»

Monkeys keep their gray matter throughout their lives

(NEWSER) - Next time you start to feel mentally superior to a chimp, think again. It turns out that while human brains shrink as they age, chimpanzee brains do not, a new George Washington University study has discovered. The findings upend the conventional wisdom that all primates saw their brains shrink over time, the Wall Street Journal explains—in fact, the researchers now suspect that only humans decline in this way.

No, we don't just use 10% of the thing

(NEWSER) - The brain is much mythologized in mainstream culture—so much so that many believed “facts” are actually fiction, reports the Smithsonian:

1. We use just 10% of our brains. Nope, brains scans show that even basic tasks use a large portion of the brain—and even a small brain injury can have big repercussions.
2. We lose brain power after 40. It does get harder to learn languages or memorize random words—but older people have bigger vocabularies, are better at judging character, and test better on social matters, like conflict resolution.
