Research and/or Creative Works

Research in the Falls laboratory examines the behaviors, neurotransmitters and neural circuits that are involved in both the elicitation and reduction of fear and anxiety. We accomplish this by combining procedures of animal learning with the techniques of behavioral neuroscience and behavioral genetics. Specific questions include:

  • What are the neural systems underlying the interaction of fear and anxiety?
  • What are the neural correlates of the anxiolytic effects of voluntary exercise?
  • How does voluntary exercise increase memory and is this related to the anxiolytic effect of exercise?
