Odors may prompt certain brain cells to make decisions

Researchers at the University of Colorado Anschutz Medical Campus have discovered that odors stimulate specific brain cells that may play a role in rapid “go/no-go” decision-making.

The study was published online Tuesday (Feb. 6) in the journal Current Biology.

The scientists focused on the , an area of the brain crucial to memory and learning. They knew that so-called “time ” played a major role in hippocampal function, but didn’t know their role in associative learning.
