6. Coronal - Neuroscience Lab Practicum - Sheep Brain Anatomy

1. corpus callosum

connects cortex of the two cerebral hemispheres

2. caudate nucleus (striatum)

part of basal ganglia, involved in motor control

3. putamen (striatum)

part of basal ganglia, involved in motor control

4. anterior commissure

connects lower portion of the two brain halves

5. internal capsule

axons of pyramidal motor system

6. optic chiasm

location where axons from eyes cross

7. optic tract

optic axons within the CNS, projects to the LGN

8. lateral ventricle

ventricle of the telencephalon

9. mammilothalamic tract

extends from the mammillary bodies to the medial and dorsal regions of the thalamus

10. fornix

axons from the hippocampus to mammillary bodies and septal nuclei

11. third ventricle

ventricle of the diencephalon

12. amygdala

involved in emotion, learning, and memory

13. thalamus

relay center, connections to neocortex

14. hypothalamus

control autonomic nervous system, pituitary gland

15. hippocampus

involved in emotion and motivation, learning and memory

16. pineal body

entrain biological clock to daylight cycle

17. cerebral aqueduct

ventricle of mesencephalon

18. superior colliculus

receives direct retinal input, control reflexive eyes movements

19. cerebellum

extrapyramidal motor structure

20. fourth ventricle

ventricle of the hindbrain

21. medulla

fibers of passage

22. septum pellucidum

separates lateral ventricles, associated with mood, receives primary input from medial forebrain bundle

23. rhinal fissure

separates smooth piriform cortex from bumpy neocortex

24. piriform cortex

associated with olfaction, receives input from olfactory bulbs

25. septal nucleus

communicates with hippocampus via the fornix, hypothalamus, and amygdala

26. cingulate gyrus

associated with emotional processing, memory, and learning

27. infundibulum

connects pituitary to hypothalamus
