The Field laboratory investigates how neural circuits in the retina process visual information and adapt to different environmental conditions. Our research combines electrophysiology, imaging, and computational approaches to understand the fundamental principles of retinal computation.

Research Focus Areas:

  • Neural circuits for motion processing
  • Adaptation to different light levels
  • Parallel processing in retinal pathways
  • Computational models of retinal function
  • Visual signal processing and encoding

Our research aims to understand how the retina performs complex computations and adapts to changing environmental conditions. This work provides insights into both fundamental principles of neural computation and potential therapeutic strategies for vision restoration.
