Research Interests:

The goals of Dr. Smirnakis’ research program are twofold:

  • To study the rules of neural plasticity and reorganization following nervous system injury in order to develop strategies that promote neural recovery,
  • To study the rules by which visual stimuli are encoded in the firing patterns of ensembles of neurons, with a particular focus on the influence that stimulus history (adaptation) has on neural responses.

Neural computations in the primate brain involve the concerted activity of many neuronal units both within and across multiple brain areas (distributed coding). In order to understand and eventually promote neural repair, it is necessary to both appreciate the fundamental principles of neural computation at the level of the local neuronal circuits and to examine in vivo how the brain as a whole adjusts to injury in one of its parts. To further these ends Dr Smirnakis' laboratory employs a variety of tools, including:

  • Functional magnetic resonance imaging (fMRI) for studying cortical reorganization following injury in humans and primates
  • Classical electrophysiology methods for studying neural coding in the early visual cortex of primates
  • In-vivo 2-photon microscopy methods for studying the structure and function of neocortical circuits and how they malfunction in information processing disorders such as autism (they are currently focusing on the study of a mouse model of autism in collaboration with Dr H. Zoghbi).
