Dopamine signals when a fear can be forgotten
Study shows how a dopamine circuit between two brain regions enables mice to extinguish fear after a peril has passed.
If time is money, here’s one way consumers value it
A study on ride-sharing opens a window into consumer behavior, measuring the benefits for businesses.
Response to infection highlights the nervous system’s surprising degrees of flexibility
Upon infection, the C. elegans worm reshuffles the roles of brain cells and flips the functions of some of the chemicals it uses to regulate behavior.
Credit where it’s due
MIT Sloan’s Christopher Palmer has produced new insights about household finance, thanks to razor-sharp empirical studies.
