amygdala
Case Study in _________ Link: Charles Whitman

amygdala
What is this an example of?
A woman was walking through the park late at night and was robbed. The next day she goes back to the same place she was robbed and walks again.
Damaged amygdala
controls endocrine system via pituitary gland
hypothalamus

hypothalamus
linked to emotion & reward seeking
hypothalamus
linked to the 4 F’s
Fighting/Fleeing
Feeding
Fornication
Freezing
hypothalamus
processes explicit memories & spatial navigation
hippocampus
decreases in size & function with age
hippocampus
Consists of 4 different lobes
Cerebral Cortex

Frontal
Parietal
Occipital
Temporal
Responsible for intelligence, personality, voluntary muscles
frontal
Responsible for spatial location, attention, motor control
parietal
Responsible for vision
occipital
Responsible for hearing, language, memory
temporal
specific body part associated with specific brain area
point-to-point mapping
________ for somatosensory (parietal) & motor (frontal) cortex
point-to-point mapping
somatosensory cortex and motor cortex are forms of ________
point-to-point mapping
left side controls the body’s right side (& vice versa)
motor cortex
left side gets input from the body’s right side (& vice versa)
somatosensory cortex
body sensations & touch
somatosensory cortex
voluntary movement
motor cortex
play a role in higher mental functions
association areas
75% of cortex
association areas
e.g., learning, remembering, thinking, speaking, linking emotion to sensations, etc.
association areas
judgment, self-control, planning, processing new memories
frontal lobe areas
damage to different _______ results in different losses
association areas
More _______ areas take up more space.
sensitive
brain area involved in planning & self-control
left prefrontal cortex
Brain damage effects depends on ______ & ___
severity & age
________ may occur after serious damage (esp. in kids), but some functions seem assigned to specific areas.
Plasticity
What is this an example of?
blindness/deafness frees up unused brain areas
