Document Summary
Sleep and arousal, cardiac, respiratory and circulatory reflexes. Pons are origin of 3 cranial nerves bridge ), reticular formation, cerebellum ( little brain ) (5, 6, 7) Cerebellum responsible for balance, motor control / equilibrium and cognitive functions. Tectum made of 2 bumps (interior colliculi [auditory functions] and superior colliculi [visual]) Thalamus ( matrimonial beds ), 2 lobes joined by massa intermedia, hypothalamus ( below the thalamus ) responsible for motor control, balance and coordination, pain center. Sensory relay center composed of multiple pairs of nuclei grey (pain center), substantia nigra and red nucleus (motor processing areas) Ventral posterior (somatosensory), medial geniculate (auditory), lateral geniculate (visual) Hypothalamus controls motivated behaviours (the 4 f"s), some nuclei have neurosecretory functions (regulates release of hormones etc. ) Why a blow to the neck can be so dangerous / fatal. Cerebellum fine tunes the way we learn, even non- motor learning. Substantia nigra is motor processing cut during progression of.
