Memory and the Brain

Human memory depends heavily on frontal structures of the brain for the creation and retrieval of memories and on temporal structures for the permanent storage of these memories.

neural plasticity

neurons are capable of changing in response to experience

provides basis for memory

neural plasticity

2 main regions involved in memory

○ region w/in temporal cortex including hippocampus
- stores new memories permanently
○ prefrontal regions
- associated w/ encoding of new memories and retrieval of old memories
- process information for storage in posterior regions

Sensory Memory

Sensory information is held briefly in cortical sensory memories so that we can process it.

visual sensory store (iconic memory)

a memory system that can effectively hold all the information in the visual display so a person can attend to it

auditory sensory store (aka echoic memory)

brief auditory memory
