PSC 137 Learning & Memory UC DAVIS Midterm 1

what does the hippocampus do in memory?

provides contextual and spatial information about fear associated stimuli

Thalamus

Processes sensory information about fear associated stimuli

Declarative Memory

Memories we are aware of and can describe verbally

Episodic Memory

autobiographical memories

semantic memory

random facts we know

non-declarative memory

unconscious and implicit memories

E.P's Amnesia

old man from San Diego that had anterograde amnesia. (anything after the damage to his brain)

Declarative memories are encoded by the:

hippocampus

Damasio's Patients

Amygdala ecodes emotional aspects of memory

Hippocampus is located in the:

temporal lobe

Hippocampus Proper

CA1, CA2, CA3 are located here

Dentate Gyrus

one of two places in the brain that never stops making neurons

Subiculum

Entorhinal Cortex

usually where alzheimer's starts

spatial and episodic memories come from the:

entorhinal cortex

The way the hippocampus gets memories and information is through the:

neocortex, then the entorhinal cortex

Entorhinal Cortex

main input to the hippocampus

Trisynaptic Loop

entorhinal-dentate gyrus-CA3-CA1

medial entorhinal cortex is in charge of the:

where pathway

place cells

when a rat explored a new environment, the hippocampus would fire in specific locations

Morris Experiment

Rats were placed in a large tub of water to prove that they could use spatial memory to get out of the water

Water Maze Experiment

Hippocampus needed for spatial memory

Context Fear Conditioning is dependent on the

hippocampus

Hippocampus is not needed for

Fear Memory

Hippocampus is needed to remember

context and places

what can't amygdala patients show

fear-conditioned response

Long Term Potentiation

an increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.

MEC pathway is the:

where pathway

Monkey Study

reveeLed that delayed memory response was due to lesions to the rhinal cortex

synaptic plasticity

the ability of synapses to change

anterograde amnesia

an inability to form new memories

retrograde amnesia

an inability to retrieve information from one's past
