Abstract

We present the results of a microscopic study of a case of unilateral cortical softening in which the internal capsule and thalamic nuclei were completely atrophied on the left side. The condition was due to vascular occlusions. Among other things, the series shows clearly the four afferent pathways which enter the ventral posterior and ventral lateral nucleus of the thalamus, where they stand out in bold relief against a background barren of cells and of thalamocortical connections. These pathways and their serial connections with the ventral lateral and the ventral posterior nucleus are shown in figure 4 B. The work of Schuster1 has given significance to the radiations of the brachium conjunctivum and to pallidal connections through the fasciculus thalamicus, or field H1. The myelination of these tracts in brains of infants has been described by Környey.2
