brain evolution
How complex environments push brain evolution February 2, 2015 [image: A hypothetical animat "brain," comprising a logic-gate network with 2 sensors, 4 hidden Markov elements, and 2 motors (credit: Larissa Albantakis/PLoS Computational Biology)] A recent study by neuroscientists offers clues about how increasingly difficult tasks have evolved the brain. They created a video game similar to the old video game Tetris, in which programmed artificial adaptive agents (“animats”) have to “catch” moving blocks of different sizes before the blocks reach the bottom (in a game for humans, that... mais »

saving brain cells -- 2/5/15 Today's *encore* selection -- 'How to Save New Brain Cells' by Tracey J. Shors. The brain can grow new neurons but these disappear unless cognitively challenged: "Fresh neurons arise in the brain every day. ... Recent work, albeit mostly in rats, indicates that learning enhances the survival of new neurons in the adult brain. And the more engaging and challenging the problem, the greater the number of neurons that stick around. These neurons are then presumably available to aid in situations that tax the mind.

This fall, I noticed myself holding back from saying it to Michael, a dear friend who was wrestling with incurable cancer. The journey metaphor was too poignant. I also avoided “Stay safe.” After all, dying is inherently precarious./.../
