Music is Cheesecake

Posted on: September 20th, 2012 by lainyday
What is music? Why do we have it? “It was an evolutionary accident,” says Dan Levitin, a professor of psychology and neuroscience at McGill University who has written books and papers on why we have music and why we like it.Levitin says the accident idea is a big one. It went public back in 1997 when Harvard professor Steven Pinker, a world-renowned author and experimental psychologist, got up in front of a group of musicologists and cognitive scientists at a meeting and said words to the effect of, “You’re all wasting your time because music is cheesecake.”

Auditory cheesecake.

“Cheesecake is interesting,” Levitin explains. “We have this great fondness for it, but we didn’t evolve a taste for cheesecake. In our hunter-gatherer days, it was an adaptive strategy to load up on fats and sweets because they were very hard to find.”

Chimps’ Answer to Einstein

Posted on: September 4th, 2012 by lainyday

Natasha, a chimp at the Ngamba Island Chimpanzee Sanctuary in Uganda, has always seemed different from her peers. She’s learned to escape from her enclosure, teases human caretakers, and scores above other chimps in communication tests. Now, Natasha has a new title: genius. In the largest and most in-depth survey of chimpanzee intelligence, researchers found that Natasha was the smartest of the 106 chimps they tested—a finding that suggests that apes have their geniuses, too.

Bees can reverse the effects of aging

Posted on: July 16th, 2012 by

A team from Arizona State and the Norwegian University of Life Sciences found that bees who have left the nest and no longer nurse the young begin aging very quickly. When persuading these bees to nurse again their ability to learn new things improved; perhaps due to increased plasticity?

Fun Fact (Well, theory at least)

Posted on: May 15th, 2012 by

Neurons evolved from amoeba-like cells. Amoeba are protists that are known to produce pseudopodia, which are protrusions from the cell body that allow the cell a degree of motility. The theory goes that these protrusions, which involve the internal restructuring of microtubules, at some point became permanent, resembling dendrites and axons that are today characteristic of neurons. For more information, see Antonio Damasio’s Self Comes to Mind (Vintage, 2010).

See the pseudopodia of the amoeba on the left, and the pyramidal neurons on the right.
