Brain damage/plasticity

Question 1

parkinsons

Answer 1

diminished substantia nigra

neurotransmitter dopamine is lacking and does not reach the brain

jagged movement, memory?

Question 2

plasticity

definition

when it occurs

Answer 2

plasticity is the ability of the brain to change its structure and relocate functions to new neural networks

occurs during early life/brain development (developmental plasticity)

due to brain injury (adaptive plasticity)

throughout life when learning (both)

Question 3

developmental plasticity

Answer 3

occurs during infancy

changes in neurone and synaptic connections due to developmental process\

allows for new behaviours after learning

Question 4

adaptive plasticity

Answer 4

changes in neurone and synaptic connections due to change in environment

allows brain to change and adapt
