Neural control of cognitivo-motor behavior
The work done in my laboratory is aimed at understanding the neural mechanisms associated with the processing of information that leads to the production of movements. For this purpose, we combine psychophysical and neurophysiological approaches.
The current projects concern (1) how the brain deals with uncertainty during motor planning; (2) the decoding of brain signals for brain-machine interface applications.
