title: Correlates of lexical processing in the activity of neuronal populations of the human brain.
abstract: Evoked discharge rate variations in the populations of subcortical (mainly striopallidal and thalamic) neurons in man during lexical processing were studied. The neuronal activity of 165 populations was recorded as a part of the diagnostic procedures in 16 parkinsonian patients treated with implanted electrodes. The patients were performing a set of psychological test involving perception and simple operations with visually presented words and pictures. A class of neuronal reactions is described which reflect endogenous brain processes associated with inner speech.
