Prof. Grodzinsky is the head of the Neurolinguistics Laboratory at the Edmond and Lily Safra Center for Brain Sciences (ELSC), and studies the neural bases of linguistic knowledge and processing. Linguistic knowledge (about how phonemes combines into morphemes and words, which in turn combine into complex meanings) is characterized by Linguistic Theory; processing ability stems from the implementation of this knowledge in cognitive structures that are supported by neural mechanisms. The Neurolinguistics Lab studies the intricate relation between these, that results in that rich ability that we humans have - the ability to express ourselves freely, and understand others who do so. We try to get a glimpse of the linguistic brain in health as well as in brain disease.
