Brain adds cells in puberty to navigate adult world
Date:3/4/2013

wn that they can mature to become part of the brain circuitry that underlies adult behavior."

Their results also showed that more of the new brain cells survived and became functional in males raised in an enriched environment a larger cage with a running wheel, nesting materials and other features than in those with a plain cage.

While people act in more complicated ways than rodents, the researchers said they hope their work ultimately sheds light on human behavior.

"We don't know if cells are added to the human amygdala during puberty," Sisk said, "but we know the amygdala plays a similar role in people as in hamsters. We hope to learn whether similar mechanisms are at play as people's brains undergo the metamorphosis that occurs during puberty."
