Visual perception and neuronal encoding, cortical plasticity, voltage-sensitive dye imaging, modeling of cortical dynamics.
We investigate how spatio-temporal patterns of cortical activity reflect short-term plastic changes and how these traces influence expectation and decision processes. Our imaging method is unique in its capability of recording electrical activity of neuronal populations at once and thus provides access to the complex dynamics observed within the brain’s network.
