This is an alternate content page containing a Hot Spot Explore Activity. It has opened in a new window.
The activity has an image with defined hotspot areas. The hotspot areas in the image are labeled as:

Fornix, projects from the hippocampus the mamillary bodies
Pulvinar Nucleus of the Thalamus
Habenular Commissure, situated in front of the pineal gland that connects the habenular nuclei on both sides of the diencephalon
Posterior Commissure, critical in the consentual pupillary light reflex
Ventral Posterolateral Nucleus of the Thalamus (VPL). Relays sensory information ascending from the body via the dorsal column-medial lemniscal tract and the spinothalamic tract.
Ventral Posteromedial Nucleus of the Thalamus, relays sensory information from the face ascending via the dorsal and ventral trigeminothalamic tracts
Optic Tract, terminates in the LGN of the thalamus
Spinothalamic tract, terminates in the VPL of the thalamus
Medial Lemniscus, terminates in the VPL of the thalamus
Periaqueductal Gray
Red Nucleus, origin of the Rubrospinal Tract
Basilar Pons (Basis Pontis)
