Picower People

Assistant Professor Linlin Fan will apply her lab’s precise “all-optical” techniques to study how serotonin might influence plasticity in memory, and whether psychedelics affect that.

Research Findings

Clinical trial finds several outcomes improved for young children when an anesthesiologist observed their brain waves to guide dosing of sevoflurane during surgery.

Research Feature

The field is called neuroscience, but neurons alone can’t operate your brain. Research is revealing how non-neural cells indispensably contribute to function, and why their roles can make them promising treatment targets in disease.
