The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Weill Cornell Medicine launches study to advance treatments for rare neurological disorder

A $1.1 million grant from the parent-caregiver-led Rare Bird Foundation to Weill Cornell Medicine is supporting the launch of a natural history study for a rare neurodevelopmental disorder that causes developmental delays and seizures called MEF2C Haploinsufficiency syndrome (MCHS).
