Research Interests:

The work done in my laboratory is aimed at understanding the neural mechanisms underlying the processing of information that leads to the production of movements. For this purpose, we combine psychophysical and neuro-physiological approaches. The current projects concern (1) the neural mechanisms for encoding, and retrieving spatial information in working memory using memory scanning tasks, and (2) the effect of degree of uncertainty on the preparatory neural activity that precedes a movement.
