the ability of the brain to grow and recignise neural connections in responce to sensory input from the environment

Question 2

define adaptive plastcity

Answer 2

the ability of neural connections in the brain to recognise in responce to learning or compensate for lost functions

Question 3

when does developemntal plasticty occur

Answer 3

changes in the brain occvur frequently throughout he fetal stage as well as infancy, childhod and adolescnce

Question 4

when does adaptive plasticty occur

Answer 4

these changes occur throughout life as learning takes place

Question 5

what are the 5 stages of plasticty

Answer 5

1. proliferation
2. migration
3. circuit formation
4. synaptic pruning
5. mylenation

Question 6

describe proliferation

Answer 6

The division and multiplication of cells

Question 7

describe migration

Answer 7

during kigration the cells move to the parts of the brain that they need to go to

Question 8

describe circuit formation

Answer 8

Circuit formation is when the cells pair together

Question 9

describe synaptic pruning

Answer 9

Synaptic pruning is when the cells that are not paired together die off

Question 10

describe mylination

Answer 10

Mylination is when the cells that are paired become jylinated with mylin sheath.

Answer 11

• conditioning
• types of learning
