T1 L17: Synaptic plasticity

Question 1

How many layers are there in the cortex?

Answer 1

6

Question 2

What is Hebb’s rule of synaptic plasticity?

Answer 2

Persistent or repetitive activity tends to induce lasting cellular changes that add to it’s stability and efficacy

Question 3

What are the 2 rules of synaptic modification?

Answer 3

1. Neurones that fire together wire together

2. Neurones that fire out of sync lose their link

Question 4

What is the purpose of strengthening and weakening of synaptic connections?

Answer 4

Allows for learning and memory formation

Question 5

What is long term potentiation (LTP)?

Answer 5

The mechanism underlying synaptic strengthening

Question 6

What is temporal long term potentiation (LTP)?

Answer 6

Summation of inputs reaches a stimulus that leads to the induction of an LTP

Question 7

What is associative long term potentiation (LTP)?

Answer 7

Simultaneous stimulation of a strong and weak pathway will induce and LTP at both pathways
