Learning and Memory Part 2

Question 1

The neural representation of memories

Answer 1

The engram

Question 2

First researcher of brain mechanisms of learning and memory. Discovered that cortical transections didn’t impact learning but large lesions did

Answer 2

Karl Lashley

Question 3

Theory that all areas of the cortex are equally involved in memory

Answer 3

Equipotentiality

Question 4

Theory that the ability to make new memories depends on brain mass

Answer 4

Mass Action

Question 5

Suffered from epilepsy as a child due to a bike accident. Had his hippocampus removed which stopped seizures but also lost the ability to form new episodic memories (anterograde amnesia)

Answer 5

Patient H.M.

Question 6

The inability to form new memories

Answer 6

Anterograde amnesia

Question 7

Has a memory of 30 seconds or less due to anterograde amnesia, caused by lesion of the hippocampus. Loves his wife though <3

Answer 7

Clive Wearing

Question 8

Theory that experience can leave a memory trace by causing long-lasting connections in synaptic connections

Answer 8

The Synaptic Plasticity Hypothesis

Question 9

Theory that if one cell repeatedly excited another, the efficacy of the synapse between them will increase

Answer 9

Hebbian plasticity

Question 10

Repetitive, high frequency stimulation of a presynaptic neuron induces a long-term increase of the synapse with the postsynaptic neuron

Answer 10

Long-term Potentiation (LTP)

Question 11

Carries information from an experience to the hippocampus

Answer 11

Entorhinal cortex

Question 12

First information station (cell group) of synaptic flow of the hippocampus

Answer 12

Dentate Gyrus (DG)

Question 13

Second information station (cell group) of synaptic flow of the hippocampus

Answer 13

CA3 pyramidal cells

Question 14

Third information station (cell group) of synaptic flow of the hippocampus

Answer 14

CA1 pyramidal cells
