Unconditioned Response (UCR)
Response automatically evoked by an unconditioned stimulus (salivation)
The physical representation of what has been learned (a connection between two brain areas would be a possible example)
Person who focused on finding the engram of memory in the cerebral cortex, proposed two principles about the nervous system: Equipotentiality & Mass Action
All parts of the cortex contribute equally to complex behaviors such as learning; any part of the cortex can substitute for any other (principle Karl Lashley proposed).
The cortex works as a whole, and the more cortex the better (principle Karl Lashley proposed).
Lateral Interpositus Nucleus (LIP)
Learning & retention occur here, one nucleus of the cerebellum (consistently found change there when testing to see which brain cells changed their responses during learning). At the start of training, those cells showed little response to the tone, but as learning proceeded, their responses increased→ correlation does not prove causation, just because change in response doesn't mean that the learning took place in that area
Directs attention toward one stimulus or another and determines which items will be stored in working memory
Delayed Response Task
A common test of working memory, requires responding to a stimulus that one heard or saw a short while later
Influence of recent experience on behavior, without necessarily realizing that one is using memory
Delayed Matching-to-Sample Task
An animal sees an object (the sample) and then, after a delay, gets a choice between two objects, from which it must choose the one that matches the sample
Delayed Non-Matching-to-Sample Task
The procedure is the same except that the animal must choose the object that is different from the sample
It has eight or more arms, some of which have a bit of food or other reinforcer at the end
Morris Water Maze Task
A task in which a rate must swim through murky water to find a rest platform that is just under the surface
One type of implicit memory is the phenomenon that seeing or hearing words temporarily increases one's probability of using them
A symptom of Korsakoff's Syndrome in which the patient takes a guess to fill in the gaps in his or her memory
Amyloid Beta Protein 42 (Absub42)
A longer protein with 32 amino acids, which accumulates, clumps with other ABsub42 molecules, and damages the membranes of axons & dendrites
