Introduction

The thalamic nuclei are paired structures of the thalamus divided into three main groups: the lateral nuclear, medial nuclear, and anterior nuclear groups. The internal medullary lamina, a Y-shaped structure that splits these groups, is present on each side of the thalamus. A midline, thin thalamic nuclei, adjacent to the third ventricle, envelops the thalamic reticular nucleus and covers each lateral thalamus. Though the thalamus can divide into approximately 60 nuclei regions, to continue, we will focus on the overarching neuroanatomy and functions of the lateral, medial, and anterior groups.
