Reticularis thalami afferents to the ventrobasal complex of the rat thalamus: an electron microscope study.

Afferents from the nucleus reticularis thalami (RT) to the thalamic ventrobasal complex were studied in the rat by looking for degenerating terminals after selective neurotoxic lesion of RT using injections of kainic acid. Several lines of evidence are presented indicating that RT afferents terminate in the VB by F type (Gray type II) terminals and that F type terminals in the VB all depend of RT neurons.
