This short video thoroughly describes the structure and function of thalamus. The video starts with the general overview of thalamus. The blood supply of the thalamus is also specified. The functional anatomy of thalamus is described by dividing it into its constituent nuclei. The function of each of the constituent nuclei of thalamus are comprehensively defined. The input and output of sensory, motor, and limbic relays are also elucidated. 0:18 Introduction 0:38 Blood supply of thalamus 0:46 Functional anatomy 0:56 Anterior nucleus 1:09 Dorsal medial nucleus 1:20 Pulvinar nuclei 1:36 Medial geniculate body 1:49 Lateral geniculate body 2:01 Intralaminar nuclei 2:13 Lateral dorsal nuclei 2:24 Ventral anterior nucleus 2:36 Ventral lateral nucleus 2:46 Ventral postero-lateral nucleus 3:01 Ventral postero-medial nucleus 3:27 Nuclei in sensory relays 4:21 Nuclei in motor and limbic relays 5:31 Input and output of miscellaneous thalamic nuclei
