(): lifelong brain adaptation to
environment
Learning and memory
Memories range from (1) to (2).
- stated facts
- ingrained motor patterns
H.M. : Almost complete () amnesia following bilateral temporal lobectom
anterograde
-Early damage in the hippocampal formation (especially entorhinal cortex).
-Old memories are intact, but encoding of new memories is difficult in the
early stage.
Alzheimer’s disease
types of non-associative memory
- () - Enhancement of an animal’s reflex responses as a result of the
presentation of a strong or noxious stimulant. - () - Decrease in the strength of a behavioral response that occurs when an
initially novel eliciting stimulus is repeatedly presented.
- Sensitization
- Habituation
() refers to an increased sensitivity to certain stimuli due to prior experience. Because it is believed to occur outside of conscious awareness, it is different from memory that relies on the direct retrieval
of information.
Priming
caudate nucleus + putamen = ()
striatum
type of memory people usually refer to when they think of “memory”
declarative memory
memory for skills, habits, and behaviors; involves learning a motor response in reaction to sensory input
procedural memory
effect of basal ganglia lesion on human memory
() patients -> (major damage to striatum)
*stimulus-motor response
association impaired.
Huntington’s disease
effect of basal ganglia lesion on human memory
() patients:
*cue-response association
impaired.
*declarative memory OK.
Parkinson’s disease
Two Models of Memory Consolidation
- ():
– Information from neocortex areas associated with sensory systems sent to medial temporal lobe for processing
– Synaptic consolidation, systems consolidation
Standard model of memory consolidation
Two Models of Memory Consolidation
- ():
– Engrams involve neocortex, but even old memories
also involve hippocampus.
Multiple trace model of consolidation
states that the hippocampus is specialized for creating a spatial map of the environment
cognitive map theory
location of a memory in the brain
engram or memory trace
