[ad_1] Summary: Researchers have discovered a new role for the hippocampus in decision-making, showing that specific brain cells, known as “time cells,” are stimulated by odors to facilitate quick “go or no-go” decisions. This study demonstrates how mice learned to associate fruity odors with a reward, allowing them to make faster and more efficient decisions. … Read more
