Question 7

procceses of Plasticity

Answer 7

1. Synaptogenesis
2. Rerouting
3. Sprouting

Question 8

Synaptogenesis

Answer 8

• formation of new connections/synaps between neurons

Question 9

Rerouting

Answer 9

• making a detour around damages area of brain, creating new pathway

Question 10

Sprouting

Answer 10

growth of axon and dentrite branches to enable the neuron to make new connections.

• • the form of new dendrites and axons to be able to make new connections

Question 11

Henry Molaison case study

Answer 11

• surgeon removes his hippocampus to reduce his seizures
• damage to temporal lobe, he was unable to form any new long term memories

Question 12

Thineas Gage Case

Answer 12
