Long Term Potentiation
This neurotransmitter is involved with Long Term Potentiation.
Glutamate
This memory has limited capacity and fades quickly without rehearsal.
Short-term Memory
This is the physical representation of what has been learned. Lashley and Thompson wanted to find this.
Engram
H.M. showed an impairment in forming new long-term memories (episodic memories) and those of facts and events (semantic memories) after his surgery. This suggests that which memory was impacted?
Explicit/declarative memory
Decrease in response to a stimulus that is presented repeatedly and accompanied by no change in other stimuli
-ex If you shoot water at an Aplysia's gills, it withdraws at first, but stops after many repetitions
Habituation
This receptor is involved in LTP. When glutamate binds, it opens only if magnesium leaves to let in sodium and calcium.
NMDA receptors
When someone is able to tell you the name of the state capital, they are displaying their ______ memory
Semantic
Which two key principles about the nervous system did Lashley propose?
Equipotentiality and Mass Action
Individuals with amnesia who play video games such as Tetris
Don't remember playing the game, but improve their performance
An increase in response to mild stimuli as a result of exposure to more intense stimuli. (reaction to poke after shock will cause the aplysia to curl up more)
Sensitization
This receptor is involved in LTP. When glutamate binds, sodium channels easily open.
AMPA receptors
Your memory of your 18th birthday party is an example of a(n) ______memory, or memory of single personally experienced events.
Episodic Memory
Lashley trained rats on a variety of mazes, then made deep cuts in their cortex. He found that each of the cuts produced:
little apparent effect
This protein is known for intracellular support structure of axons (keeps axons structural) and is known to break down and form tangles in Alzheimer's disease.
Tau protein
During this hippocampus and spatial memory experiment, rat swims through murky water to find platform that it can't see
Morris water maze
This rule suggests "what fires together, wires together."
Hebb's rule
An influence of experience on behavior, even if the influence is not recognized. This type of memory includes procedural memory.
Implicit memory
This is the part of the brain that Thompson find was associated with learning when studying classical conditioning in rabbits.
Cerebellum, more specifically the lateral interpositus nucleus.
This protein is caused by the genes controlling early-onset Alzheimer's disease
Amyloid-β
It is believed that Hebbian synapses may be critical for:
Associative learning
Activity of the synapse, paired with an action potential in the post synaptic cell, strengthens that synapse.
"Hebbian" synapse
This type of memory involves deliberate recall of information that one recognizes. Those with Alzheimer's have impairments in this type of memory.
Declarative/Explicit
Which two stimuli did Thompson associate when studying classical conditioning in rabbits?
Puff of air and tone
Brain damage caused by prolonged thiamine deficiency and often due to chronic alcoholism
Korsakoff's syndrome
This process was thought to be the neural marker of learning and memory.
