title: [Sources of thalamocortical afferentation of the area of forelimb representation in the first somatosensory zone of the cerebral cortex in the cat].
abstract: Retrogradely labelled thalamic neurons--the sources of afferentation in the focus of maximal activity evoked by stimulation of n. radialis--were studied in adult cats by means of microiontophoretic injections of horseradish peroxidase into the first somatosensory zone of the cerebral cortex. The labelled cells were predominantly found in the thalamic nucleus ventralis posterolateralis; some cells (a minor part) were also found in the nucleus ventralis posteromedialis. The labelled neurons in these nuclei were distributed in groups whose composition according to many morphological characteristics was heterogeneous.
