Visual NeuroPlasticity Workshop

January 10, 2024

10:00 AM to 4:00 PM ET

Purpose: The synaptic basis of neuroplasticity may involve long term potentiation or depression (LTP/LTD), but there are also many possible polysynaptic, cellular, circuit, and behavioral mechanisms. In the visual system alone, myriad concepts guide research at the various levels of inquiry including: synapse formation/maintenance, adaptive/maladaptive, experience dependent/homeostatic, familiarity/learning and memory/recovery of function.  The goal of this workshop is to bring together various lines of investigation for a better understanding of the full process.

The workshop will be virtual, and is free to attend. The event will be live captioned. For questions or other reasonable accommodations to participate, please contact Alicia Kerr (alicia.kerr@nih.gov) at least 72 hours prior to the event.

Oculomotor learning is a classic example of neuroplasticity, involving cerebellar synapses, brain circuits, and visual signals. Circuit tracing using Brainbow multicolor labeling.
