31

folia

surface of cerebellum, highly folded neural cortex

32

purkinje cells

large branched cells in cerebellar cortex that receive input from 200,000 synapses

33

arbor vitae

highly branched, internal white matter of cerebellum that relay info to purkinje cells

34

ataxia

damage from trauma, stroke, or drinking, loss of muscle coordination

35

superior colliculus

visual nuclei in tectum of midbrain

36

inferior colliculus

auditory nuclei in tectum of midbrain

37

substantia nigra

part of tegmentum of midbrain that reg act in basal nuclei

38

cerebral peduncles of midbrain

connect primary motor cortex w motor neurons in brain and spinal cord, carry ascendin sensory info to thalamus

39

pineal gland

found in epithalamus and secretes melatonin

40

thalamus function

filters ascending sensory info for primary sensory cortex and relays info between basal nuclei and cerebral cortex

41

thalamus anterior goup

part of limbic system

42

thalamus medial group

integrates sensory info for projection to the frontal lobes

43

thalamus ventral group

projects sensory info to primary sensory cortex; relays info from cerebellum and basal nuclei to motor area of cerebral cortex

44

thalamus pulvinar

integrates sensory info for projection to association areas of cerebral cortex

45

lateral geniculate nuclei

project visual info to the visual cortex

46

medial geniculate nuclei

project auditory info to the auditory cortex

47

thalamus lateral group

integrates sensory info and influences emotional states
