Scripps Research Unveils Brain Neurons That Control First Bite and Drinking Behavior

Do you grab a fork and take a first bite of cake, or say no and walk away? Our motivation to eat is driven by a complex web of cells in the brain that use signals from within the body, as well as sensory information about the food in front of us, to determine our behaviors.

Integrating Ultrasound with Genetics to Precisely Modify Neurons in the Brain

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the brain.
