Document Summary

Anterior on the left, posterior on the right. Thalamus is a midline structure: split into the left and right by the third ventricle, corpus callosum is overtop. Notice how the internal capsule separates the basal ganglia and the thalamus. From the anterior view we can see how the third ventricle separates the thalamus. The thalamus is a relay station for most things in the cerebral cortex: motor things, direct or indirect, sensory things. Neurons within the thalamus that help control excitability. Categories of the thalamic nuclei: modality specific (to primary cortical areas, sensory and motor, association (anterior, md and pulvinar, non-specific (reticular to thalamic for arousal and intralaminar group to all areas for cortical arousal) Thalamic nuclei are named based on their position in the thalamus, for example: va ventral anterior nucleus, md medial dorsal, vpl ventral posterior lateral. Nerves carry tactile, hearing, visual information into the body: Information all goes through the thalamus before going to the cerebral cortex.
