Other Brain Areas in Memory
- INV asked 2 patients with parietal
lobe damage to describe various
events from their past
- when tested this way, their
episodic memory appeared
sparse, almost devoid of details
- However, INV asked follow up q's
- patients answered reasonable detail indicating their
episodic memories were intact as well as speech and
willingness to cooperate
- what was lacking was
ability to elaborate on
memory
spontaneously

- patients answered reasonable detail indicating their

willingness to cooperate
- However, INV asked follow up q's
- Usually, when we recall events, one thing
reminds us of another and we add details
until we say all we know
- In people with parietal lobe damage
that process of associating one
piece of another is impaired
- In people with parietal lobe damage

- when tested this way, their

sparse, almost devoid of details
- other brain areas are important for
learning and memory
- Amygdala important for
fear of memory
- Amygdala important for
fear of memory
- People with damage to anterior and
inferior regions of temporal lobe suffer
semantic dementia
- loss of semantic memory
- one patient while riding down road saw
some sheep and asked what they were
- problem wasn't that he couldn't remember the
word it was that he never seen sheep before
- lost the concept not the word
- lost the concept not the word
- problem wasn't that he couldn't remember the
word it was that he never seen sheep before
- not sole point of storage for semantic memory
- areas store some of info and serve as hub for
communicating with other brain areas to bring
together a full concept
- areas store some of info and serve as hub for
communicating with other brain areas to bring

- loss of semantic memory
- serious deficits in
semantic memory occur
only after bilateral damage
- people with damage to temporal
cortex is just one hemisphere
perform approximately normally
- people with damage to temporal
cortex is just one hemisphere
perform approximately normally
- parts of prefrontal cortex are important
for learning about rewards and
punishments
- basal ganglia also learn about ears
values of various actions but learn slowly
based on average reward over long period
of time
- prefrontal cortex responds more
quickly, based on most recent
events
- basal ganglia also learn about ears
values of various actions but learn slowly
based on average reward over long period
of time
- cells in orbitofrontal cortex respond based on how
that reward compares to other possible choices.
- cells in orbitofrontal cortex are also
important for self control
- once between small reward and large
you try to retrain your impulse to take
immediate reward
- if orbitofrontal cortex is damaged or temporarily inactivated
you become more likely to tai the immediate reward
- if orbitofrontal cortex is damaged or temporarily inactivated
you become more likely to tai the immediate reward
- cells in orbitofrontal cortex are also
important for self control
- Children have trouble restraining their impulses,
because the prefrontal cortex is slow to mature
