Biologists identify genes regulating sleeping and feeding
Date:6/10/2010

ies' movement to determine resulting sleep behavior.

Their results showed a three-to-four-fold reduction in sleep in starved flies missing the Clock and cycle genes compared to flies possessing these genes. The findings therefore suggest that both Clock and cycle help the flies to regulate sleep when they are food deprived.

"This is a significant advance in how we approach behavioral genetics," said Alex Keene, PhD, a post-doctoral researcher in NYU's department of biology and the study's lead author. "We know that the brain is wired to engage in more than one behavior at a time, but less clear is how the brain chooses between these behaviors. These findings are transformative because they show that a gene can control sleep in a context-specific fashion. In the future, we will need to study animals in different environmental conditions in order to fully understand how the brain controls behavior. "
