LAB 4CORONAL VIEW

Returning Structures – Lab 1

• Lateral olfactory tract• Optic tract• Optic chiasm• Mammillary bodies

Returning Structures – Lab 2

• Corpus callosum• Fornix• Mammillary bodies• 3rd ventricle• Cerebral aqueduct• Pineal body• Superior & inferior colliculi

Returning Structures – Lab 3

• Caudate nucleus• Putamen• Globus pallidus• Hippocampus• Lateral ventricles• Internal capsule

(but with a new name!)• LGN• MGN

New Structures• Corona radiata

• Series of axons that relay mostly sensory information from the thalamus cortex

• Previously seen as the internal capsule as it passed through the basal ganglia

New Structures

• Reticular formation• Sleep/wakefulness, attention, movement• Vital reflexes• Input from the hypothalamus

New Structures

• Reticular formationIncludes:• Raphe nuclei

• Serotonin production• Locus coeruleus

• Norepinephrine production

New Structures

Substantia Nigra

• Involved in basal ganglia functioning

• Produces and secretes dopamine
