Across 4. consists of tectum & tegmentum 6. involved in planning/coordinating movements; more neurons than the rest of the brain combined 10. consists of hypothalamus & thalamus 12. formed by third ventricle; surrounded by tectum & tegmentum; connects 3rd & 4th ventricle 13. liquid containing glucose & specialized proteins; "supports" brain 14. consists of the hippocampus and amygdala (involved in memory/learning & emotions) 18. ventricle located in the telencephalon; consists of 4 parts 19. contains the caudate nucleus & putamen 21. only area not covered by the BBB; induces vomiting 22. area that maintains homeostasis 24. "bridge" between cerebellum & cerebral hemispheres 25. fiber bundle consisting of hippocampal efferents 26. disease caused by degeneration of DA neurons in the caudate & putamen; 80% loss for symptoms; inhibits thalamus - inhibits movement 27. Ventricle located between cerebellum & brainstem; turns into the central canal of S.C

Down 1. cells whose axons turn into parallel fibers 2. basal ganglia & limbic system 3. ventricle located in the diencephalon; surrounded by thalamus 5. huge dendritic trees; excited by parallel fibers & sends inhibitory messages to the cerebellum 7. consists of the telencephalon & diencephalon 8. Network of hollow spaces (lumen) that represented the differentiated cavities of the neural tube 9. area containing photoreceptors & secretes melatonin to regulate circadian rhythm 11. condition caused by the build-up of CSF in 3rd and lateral ventricles 12. tissues in the ventricles that make CSF 15. consists of striatum, pallidum, and subthalamic nuclei 16. sensory relay station (except for olfaction) 17. degenerative disease in caudate, putamen, and globus pallidus; doesnt inhibit thalamus - uncontrollable movements 20. consists of the substantia nigra & red nucleus; regulates mood, pleasure, pain 22. consists of cerebellum, pons, and medulla 23. area that regulates consciousness, alertness, arousal 28. consists of the superior & inferior colliculi
