Slide 13: Midbrain to Thalamus Transition

Identify:

• Basilar Pons
• Decussation of the Superior Cerebellar Peduncles (SCPDX)
• Medial Longitudinal Fasciculus (MLF)
• Central Tegmental Tract (CTT)
• Hypothalamo-Autonomic Tract (HAT)
• Periaqueductal Gray (PAG)
• Superior Colliculus (SC)
• Medial Lemniscus (ML)
• Spinothalamic Tract (STT)
• Brachium of the Inferior Colliculus (BIC)
• Medial Geniculate (MG)
• Lateral Geniculate (LG)
• Optic Radiations (OR)
• Pulvinar nucleus of thalamus (PUL)
• Pineal Gland (PIN)
• Corpus Callosum (Splenium)
• Fornix
• Hippocampus
• Alveus of the Hippocampus
• Body of the Lateral Ventricle
• Temporal (Inferior) Horn of the Lateral Ventricle
• Tail of the Caudate Nucleus
• Stria Terminalis

Note:

• The Optic Radiations are projections from the Lateral Geniculate Body of the Thalamus to the Visual Cortex.
• The Fornix is continuous with the Alveus of the Hippocampus.
• The Stria Terminalis is a tract connecting the Amygdala in the temporal lobe with the Hypothalamus.
• The Caudate Nucleus and the Stria terminalis follow the shape of the ventricles from the temporal lobe to the frontal lobe.
