Research Interests

Consider the situation of a baseball player at home plate. In order to successfully hit the ball, his brain must rapidly process sensory cues (e.g., the trajectory of the ball), decide on the appropriate response (e.g., to swing or not to swing), and plan the action with a high degree of precision (e.g., put the bat in the right place at just the right time). Dr. Verstynen's research centers on these fast response selection abilities that are at the border of perception and action. Specifically his lab is interested in how the neuroanatomical architecture of brain pathways reflects aspects of their computational functions, with an emphasis on sensorimotor planning and skill learning. Within this framework, his research centers on three main themes:

  1. Selecting or unselecting actions: How do we quickly convert sensory cues into motor plans? How do we stop a planned action? How do these abilities break down in different populations?
  2. Dynamics of skill learning: Why are some skills learned quickly (e.g., visuomotor adaptation) while others require days or weeks of practice (e.g., learning to play a piano)? What are the computational and neural mechanisms involved?
  3. Structure-function associations: Does the topography (i.e., “wiring diagram”) of a neural pathway reveal aspects of its computations? What features predict individual differences in the organization or integrity of these connections?
