Salk scientists discover previously unknown requirement for brain development Public release date: 20-Jun-2013 [ Print | E-mail Share ] [ Close Window ] Contact: Kat Kearneykkearney@salk.edu 619-296-8455Salk Institute Scientists at the Salk Institute for Biological Studies have demonstrated that sensory regions in the brain develop in a fundamentally different way than previously thought, a finding that may yield new insights into visual and neural disorders. In a paper published June 7, in Science, Salk researcher Dennis O'Leary and his colleagues have shown that genes alone do not determine how the cerebral cortex grows into separate functional areas. Instead, they show that input from the thalamus, the main switching station in the brain for sensory information, is crucially required.

The prefrontal cortex (PFC) is the anterior part of the frontal lobes of the brain, lying in front of the motor and premotor areas. This brain region has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. The most typical psychological term for functions carried out by the prefrontal cortex area is executive function. Prefrontal cortex
