TRANSCRIPT
• Central Nervous System (CNS)–Forebrain: “New and Old Cortex”–Midbrain–Hindbrain
• Peripheral Nervous System–Somatic (Skeletal)–Autonomic
How is the nervous system relevant to behavior?
Brain
Spinal cord
(nerves) afferent and efferent
(tracts)
(See Gleitman, p. 51)
• Medial-Lateral:
• Anterior-Posterior:
• Ventral-Dorsal:
“Geography” of the spinal cord and brain:
middle to side
head to tail
front to back
forehead to back
chin to top
middle to side
spinal cord brain
How is the central nervous system organized?
Nervous System
Central
Peripheral
Brain
Spinal Cord
Autonomic
Skeletal
Forebrain
Midbrain
Hindbrain
Sympathetic(arousing)
Parasympathetic (calming)
ReciprocalInhibition
• Chemical and electrical stimulation• Lesioning and ablating• Electroencephalogram (EEG)
(See Gleitman p. 44)
• CAT, PET, MRI, and FMRI scans(See Gleitman p. 45)
How do we observe and study the central nervous system in action?
Thalamus
HypothalamusAmygdala
Hippocampus
Reticular Activating System
Midbrain:
Cerebellum
Limbic structures:
Hindbrain:
Cerebral cortex
(Corpus callosum)
Forebrain:
Medulla
See Gleitman pp. 9, 49)
Longitudinal fissure
Central fissure
(Primary somatosensory area )
Parietal lobe
front
Frontal lobe
(Primary motor area)
(including Broca’s area)
(including auditory area)
Temporal lobe (including Wernicke’s area)
(See Gleitman, p. 52)
Occipital lobe
(Visual area)
What are some of the specialized functions of the Cerebral Cortex?
Frontal lobe
