Cards

Term
amnesia
Definition
partial or total loss of memory
Term
anterograde amnesia
Definition
inability to remember events subsequent to a disturbance of the brain such as head trauma, electroconvulsive shock, or certain neurodegenerative diseases
Term
conditioned response CR
Definition
in Pavlovian conditioning, the learned response to a formerly neutral conditioned stimulus (CS)
Term
conditioned stimulus CS
Definition
in Pavlovian conditioning, an originally neutral stimulus that, after association with an unconditioned stimulus (UCS), triggers a conditioned response
Term
declarative memory
Definition
ability to recount what one knows, to detail the time, place, and circumstances of events; often lost in amnesia
Term
drug induced behavioral sensitization
Definition
escalating behavioral response to the repeated administration of a psychomotor stimulant such as amphetamine, cocaine, or nicotine; also called behavioral sensitization
Term
emotional memory
Definition
memory for the affective properties of stimuli or events
Term
entorhinal cortex
Definition
located on the medial surface of the temporal lobe; provides a major route for neocortical input to the hippocampal formation; often degenerates in Alzheimers disease
Term
epidermal growth factor (EGF)
Definition
Nerotrophic factor that stimulates the subventricular zone to generate cells that migrate into the striatum and eventually differentiate into neurons and glia
Term
episodic memory
Definition
autobiographical memory for events pegged to specific place and time contexts
Term
explicit memory
Definition
memory in which a subject can retrieve an item and indicate that he or she knows that the retrieved item is the correct item (i.e., conscious memory)
Term
instrumental conditioning
Definition
learning procedure in which the consequences (such as obtaining a reward) of a particular behavior (such as pressing a bar) increase or decrease again; also called operant conditioning
Term
Korsakoff's syndrome
Definition
permanent loss of the ability to learn new information (anterograde amnesia) and to retrieve old information (retrograde amnesia) caused by diencephalic damage resulting from chronic alcoholism or malnutrition that produces a vitamin B1 deficiency
Term
learning set
Definition
an understanding of how a problem can be solved with a rule that can be applied in many different situations
Term
memory
Definition
the ability to recall or recognize previous experience
Term
nerve growth factor (NGF)
Definition
neurotrophic factor that stimulates neurons to grow dendrites and synapses and, in some cases, promotes the survival of neurons
Term
neuritic plaque
Definition
area of incomplete necrosis (dead tissue) consisting of a central protein core (amyloid) surrounded by degenerative cellular fragments; often seen in the cortex of people with senile dementia's such as Alzheimer's disease
Term
parahippocampal cortex
Definition
cortex located along the dorsal medial surface of the temporal lobe
Term
Pavlovian conditioning
Definition
learning procedure whereby a neutral stimulus (such as a tone) comes to elicit a response because of its repeated pairing with some event (such as the delivery of food); also called classical conditioning or respondent conditioning
Term
perihinal cortex
Definition
cortex lying next to the rhinal fissure on the base of the brain
Term
priming
Definition
using a stimulus to sensitize the nervous system to a later presentation of the same or a similar stimulus
Term
procedural memory
Definition
ability to recall a movement sequence or how to perform some act or behavior
Term
retrograde amnesia
Definition
inability to remember events that took place before a disturbance of the brain
Term
unconditioned stimulus
Definition
a stimulus that unconditionally-naturally and automatically- triggers a response
Term
visuospatial learning
Definition
using visual information to identify an objects location in space
