Cards

Term
Acquisition of new information or knowledge
Definition
learning
Term
Retention of learned information
Definition
memory
Term
Memory of facts and events – conscious access
Definition
declarative memory
Term
Procedural memory (skills and habits),
conditioning
Definition
nondeclarative memory
Term
declarative memory takes place where?
Definition
medial temporal lobe; decephalon
Term
2 parts of nondeclarative memory
Definition
procedural memory; classical conditioning
Term
procedural memory takes place where?
Definition
striatum
Term
classical condition skeletal musculature takes place where? "" emotional responses where?
Definition
cerebellum; amygdala
Term
Permanent storage in long-term memory requires
Definition
consolidation
Term
Loss of memory and/or loss of the ability to learn
Definition
amnesia
Term
Memory trace
Definition
engram
Term
physical location of a memory
Definition
Memory trace (engram)
Term
Experiments on cortical basis of learning by
Definition
Karl Lashley
Term
Lashley found a correlation between
the severity of behavioral deficit and
size (but not location) of cortical
lesions called
Definition
(“equipotentiality”).
Term
Conceptual link between memory storage and
representation of stimuli within the cortex
Definition
Donald Hebb
Term
Stimulus activates a...
Definition
cell assembly
Term
reciprocally connected and
distributed set of cells
Definition
cell assembly
Term
Reverberation of activity within the assembly corresponds to
Definition
shortterm memory
Term
Persistence of activation leads to________of the assembly’s
connections (“growth process”)
Definition
strengthening
Term
Subsequently, the assembly can be triggered by a weaker stimulus,
or by only a portion of the stimulus. The reciprocal connection will
automatically
Definition
“complete” the cortical representation of the stimulus.
Term
Partial destruction of the assembly may not cause
Definition
loss of
all memory
Term
Responses of neurons in inferior temporal cortex (IT) to faces show
Definition
learning-related changes over time
Term
Responses of neurons in inferior temporal cortex (IT) to faces show
learning-related changes over time. These neurons underlie both
Definition
recognition and memory.
Term
Patient H.M.
Definition
Bilateral resection of the medial temporal lobe (1953) to ameliorate
severe epileptic attacks, possibly due to a bicycle accident at age 9 (“a
frankly experimental operation”)
Term
memory appears to have a distinct neural
substrate. Their work inspired animal models of amnesia
Definition
Scoville and Milner
Term
H.M. suffers from
Definition
partial retrograde amnesia for events during the
years preceding the operation, complete anterograde amnesia for all
events following the operation
Term
learn new tasks and skills
Definition
procedural memory
Term
Structures in the medial temporal lobe are involved in the
Definition
consolidation of declarative memories
Term
DNMS
Definition
Delayed non-match to sample
task
Term
Delayed non-match to sample
task (DNMS) probes
Definition
recognition memory
Term
Lesions of the medial temporal lobes cause deficits in
Definition
recognition
memory
Term
Study of R.B. and other patients (G.D. etc.) showed that damage
limited to (a specific subfield of) the hippocampal formation was
sufficient to produce
Definition
clinically significant anterograde memory loss.
Term
Other structures involved in
declarative memory are
located in the
Definition
diencephalon
Term
Alcoholism (thiamine
deficiency) results in damage
to the mamillary bodies and
Definition
Korsakoff’s syndrome.
Term
Medial temporal lobe areas are connected to the frontal lobes
via the
Definition
dorsomedial nucleus of the thalamus.
Term
Lesions of prefrontal cortex result in deficits of working memory
used for
Definition
problem solving as well as planning of behaviors
(recall Phineas Gage…)
Term
Test for deficits often associated with
prefrontal cortical damage...
Definition
Wisconsin
card-sorting test
Term
Working memory is often studied in
Definition
delayed response tasks
Term
Neurons in monkey prefrontal cortex show
Definition
increased activity during
a delay period (no stimulus present).
Term
Neural activity corresponds to
Definition
mental representation of a “goal”
