Corticofugal feedback influences the responses of geniculate neurons to moving stimuli.

abstract：:Here we aim to evaluate the ability of transcranial direct current stimulation (tDCS), which is applied over Wernicke's area and its right homologue, to influence lexical decisions and semantic priming and establish an involvement for temporo-parietal areas in lexical and semantic processing. Thirty-two subjects (17 w...
