Language formulation/generation is a complex event that involves the participation of neocortical and subcortical structures. Findings from the stimulation mapping of the frontal–parietal–temporal regions in the dominant cerebral hemispheres, from a large number of neurosurgical patients undergoing tissue ablation, indicate that language functions in the brain are organized in columnar layers. With functional overlap of functions in the same tissues, language generation seems to unfold through different stages before its behavioral manifestations. Motor integration is only one function of the subcortical structures, such as the thalamus and basal ganglia. A substantial number of thalamic and basal ganglia cells either direct the system to the processes that underlie the use of language and its generation or serve as those processes directly. |
