A study in the journal SLEEP shows Military service members who have trouble sleeping prior to deployments may be at greater risk of developing PTSD, depression and anxiety once they return home. Lead author Philip Gerhman's study shows that assessment of insomnia symptoms predeployment may help identify those at highest risk for subsequent adverse mental health outcomes and plan appropriate treatment.

Dr. Ron Anafi and others in the Division of Sleep Medicine show that sleep is not just for the brain. See article in BMC Genomics.

CSCN 10th Annual Research Retreat
Thursday, May 30, 2013

Keynote Speaker
Joseph Takahashi is Chair of the Department of Neuroscience and an Investigator of the Howard Hughes Medical Institute at UT Southwestern Medical Center. He currently holds the Loyd B. Sands Distinguished Chair in Neuroscience.

Dr. Takahashi has pioneered the use of forward genetics and positional cloning in the mouse as a tool for discovery of genes underlying neurobiology and behavior, and his discovery of the mouse and human clock genes led to a description of a conserved circadian clock mechanism in animals.
