How the Brain Turns Down the Volume on Your Noisy Body

The brain’s ability to recognize and tune out sensory stimuli produced by the body’s own actions — to distinguish ‘self’ from ‘other’ — is a long recognized, yet poorly understood, biological phenomenon. Nathanial Sawtell, a principal investigator at Columbia’s Mortimer B. Zuckerman Mind Brain Behavior Institute, focuses his research on uncovering how it works.

Tangled Up and Blue: Neurons’ Faulty Wiring Leads to Serotonin Imbalance, Depression-Like Behavior in Mice

Columbia scientists have identified a gene that allows neurons that release serotonin — a neurotransmitter that regulates mood and emotions — to evenly spread their branches throughout the brain. Without this gene, these neuronal branches become entangled, leading to haphazard distribution of serotonin, and signs of depression in mice.
