What is Double dissociation between syntactic gender and picture naming processing: A brain stimulation mapping study about?

## Abstract Neural foundations of syntactic gender processing remain poorly understood. We used electrostimulation mapping in nine right‐handed awake patients during surgery for a glioma within the left hemisphere, to study whether the cortico‐subcortical structures involved in naming versus syntactic gender processing are common or distinct. In French, the article determines the grammatical gender. Thus, the patient was asked to perform a picture naming task and to give the appropriate article for each picture, with and without stimulation. Cortical stimulation elicited reproducible syntactic gender disturbances in six patients, in the inferior frontal gyrus (three cases), and in the posterior middle temporal gyrus (three cases). Interestingly, no naming disorders were generated during stimulation of the syntactic sites, while cortical areas inducing naming disturbances never elicited grammatical gender errors when stimulated. Moreover, at the subcortical level, stimulation of the white matter lateral to the caudate nucleus induced gender errors in three patients, with no naming disorders. Using cortico‐subcortical electrical mapping in awake patients, we demonstrate for the first
