This document provides a summary of returning structures from previous labs and new structures seen in the coronal view of the brain. It lists structures seen in Labs 1-3 such as the lateral olfactory tract, optic tract, corpus callosum, and hippocampus. New structures discussed include the corona radiata, which relays sensory information from the thalamus to the cortex, the reticular formation which is involved in sleep, movement and vital reflexes, and the substantia nigra which produces dopamine and is involved in basal ganglia functioning.

1. LAB 4
CORONAL VIEW

2. Returning Structures – Lab 1
• Lateral olfactory tract
• Optic tract
• Optic chiasm
• Mammillary bodies

3. Returning Structures – Lab 2
• Corpus callosum
• Fornix
• Mammillary bodies
• 3rd ventricle
• Cerebral aqueduct
• Pineal body
• Superior & inferior colliculi

4. Returning Structures – Lab 3
• Caudate nucleus
• Putamen
• Globus pallidus
• Hippocampus
• Lateral ventricles
• Internal capsule
(but with a new name!)
• LGN
• MGN

5. 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

6. New Structures
• Reticular formation
• Sleep/wakefulness, attention, movement
• Vital reflexes
• Input from the hypothalamus

7. New Structures
• Reticular formation
Includes:
• Raphe nuclei
• Serotonin production
• Locus coeruleus
• Norepinephrine production

8. New Structures
Substantia Nigra
• Involved in basal
ganglia functioning
• Produces and
secretes dopamine
