The projections of single thalamic neurons onto multiple visual cortical areas in the cat.

Fluorescent dyes Fast Blue and Nuclear Yellow injected into pairs of visual cortical and parietal 'association' cortical areas in the cat revealed the presence of retrogradely double-labeled cells in the intralaminar nuclei and lateral posterior-pulvinar complex of the thalamus. These results demonstrate the projection of individual thalamic neurons onto multiple cortical areas.
