“…However, the subcortical systems that may mediate these responses are not yet known [Albe-Fessard and Fessard, 1963;Bignall, 1967;Bruner, 1965;Narikashvili et al, 1969;Phillips et al, 1972;Rutledge, 1963], While the present data indicate that both LP and VA have projections to parietal cortex, they have not identified the system(s) which mediate the cortical polysensory responses. On the one hand, LP exhibits polysensory convergence [Huang and Lindsley, 1973;Kreindler et al, 1968], and the visual properties of LP cells are not dissimilar to those of cells in parietal cortex Dubner, 1969, 1971;Godfraind et al, 1972], Thus, LP could be mediating at least a portion of the cortical polysensory responses.…”

Thalamic projections to parietal regions of cerebral cortex were investigated in the cat by retrograde degeneration and retrograde transport techniques. Studies of retrograde cellular changes indicate cortically projecting cells in the lateroposterior nucleus (LP), rostral pulvinar (Pul), and the ventral part of the laterodorsal nucleus (LD). When lesions were placed in the cortex of young kittens, clear chromatolytic changes and cell loss were also consistently observed in middle and caudal parts of the ventroanterior nucleus (VA). Investigations of retrograde transport following intracortical injections of horseradish peroxidase have confirmed the results of retrograde degeneration studies by demonstrating cortically projecting cells in VA, LP, LD, and Pul. Retrograde transport studies also indicate cortically projecting cells in the central lateral nucleus. Material from both experimental techniques demonstrates a loose topographic organization of the projections from the lateral thalamus. Anterior parts of LP project to the anterior lateral gyrus and anterior middle suprasylvian gyrus. Middle LP and rostral Pul project to the middle suprasylvian gyrus.
