Falls Laboratory of Behavioral Neuroscience

Research in the Falls Laboratory examines the neurobiological mechanism involved in both the elicitation and reduction of fear and anxiety. We accomplish this using a variety of techniques including behavioral assessment of fear and anxiety, pharmacological manipulations, and neuroanatomical and molecular techniques. Specific questions include:

  • What are the neurobiological mechanisms underlying the interaction of fear and anxiety and stress?
  • What are the neurobiological mechanisms of the anxiolytic effects of voluntary exercise?
  • How does stress interact with the anxiolytic effect of exercise?
