| medullary layers of thalamus | Layers of myelinated fibres that appear on transverse sections of the thalamus; the lamina medullaris externa marks the ventral and lateral borders of the thalamus and delimits it from the subthalamus and reticular nucleus of thalamus; the lamina medullaris interna is interposed between the mediodorsal and ventral nuclei of the thalamus and encloses the intralaminar nuclei (centromedian, paracentral, and central lateral nuclei). Synonym: laminae medullares thalami, medullary layers of thalamus. (05 Mar 2000) |

| medullary stria of thalamus | A narrow, compact fibre bundle that extends along the line of attachment of the roof of the third ventricle to the thalamus on each side and terminates posteriorly in the habenular nucleus. It is composed of fibres originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus. Synonym: stria medullaris thalami, stria fornicis, stria ventriculi tertii. (05 Mar 2000) |
| reticular nucleus of thalamus | A sheet of fairly large neurons covering the lateral, ventral, and rostral surfaces of the thalamus; its reticular appearance is caused by the numerous fascicles of the thalamic peduncles which traverse the nucleus The nucleus receives numerous fibres from the cerebral cortex but it has no cortical projection. Synonym: nucleus reticularis thalami. (05 Mar 2000) |
| posterior medial nucleus of thalamus | Medial part of the ventrobasal nuclear complex. See: ventral posterior nucleus of thalamus. Synonym: nucleus ventralis posteromedialis thalami. (05 Mar 2000) |
| intralaminar nuclei of thalamus | Collective term denoting several cell groups embedded in the internal medullary lamina of the thalamus: central lateral nucleus, paracentral nucleus, and farthest caudally, the large centromedian nucleus. The first two of these receive afferents from the cerebral cortex, brainstem, reticular formation, cerebellum, and spinal cord, and project more or less diffusely to large regions of the frontal and parietal cortex. See: centromedian nucleus. Synonym: nuclei intralaminares thalami. (05 Mar 2000) |
| lateral nucleus of thalamus | The largest of the major subdivisions of the thalamus; the composite lateral nucleus includes, from before backward, the nucleus lateralis anterior or dorsalis, nucleus lateralis intermedius, nucleus lateralis posterior, and pulvinar; together, these cell groups form most of the free dorsal surface of the posterior half of the thalamus and project to a very large region of parietal, occipitoparietal, and temporal cortex; its afferent connections are largely obscure, but the nucleus lateralis posterior and the pulvinar receive a projection from the superior colliculus. Synonym: nucleus lateralis thalami. (05 Mar 2000) |
| thalamus |
An area of the brain consisting of 2 relatively large masses of gray matter. The thalamus relays information from most sensory organs to the outer region of the cerebrum or cerebral cortex; receives and processes messages from the body concerning heat, cold, pain, pressure, and touch; and influences motor activity of the cerebral cortex.

| thalamus |
The largest of the 4 subdivision of the diencephalon bordering the upper lateral wall of the third ventricle dorsal to the hypothalamic sulcus. It is consists of many nuclei with extensive cortical and subcortical connections. It functions as a motor and sensory relay station, and plays a role in arousal, attention, memory, consciousness, and expression of emotion.
