Summary
Women are at increased risk of developing fear-related anxiety disorders. We have recently discovered that there sex-specific regulatory mechanisms in the brain that are associated with differences in the control of fear. In this proposal, we will determine whether novel DNA modifications in the female brain are responsible for establishing sex differences in brain states that make the brain more or less responsive to fear-related learning.

Summary
Production of new neurons in the hippocampus of adult animals plays a role in regulating learning and memory, and this production slows continuously with increasing age. Here we explore ways to activate dormant populations of neurogenic precursor cells in the hippocampus to produce new neurons. Since the precursor cells are still present in the hippocampus of an aged animal these studies will provide unequivocal evidence for their importance in reversing age-related cognitive decline and dementi ....Production of new neurons in the hippocampus of adult animals plays a role in regulating learning and memory, and this production slows continuously with increasing age.
