Making Connections in the Eye

August 8, 2013 12:06 pm | by Anne Trafton, MIT News Office | News | Comments

The human brain has 100 billion neurons, connected to each other in networks that allow us to interpret the world around us, plan for the future, and control our actions and movements. MIT neuroscientist Sebastian Seung wants to map those networks, creating a wiring diagram of the brain that could help scientists learn how we each become our unique selves.

Study Ties Higher Blood Sugar to Dementia Risk
