Hint	Answer
plasticity	the brains tendency to change and adapt as a result of experience and new learning
child vs adult	children have more synaptic connections
	synaptic pruning
negative plasticity	drugs and old age
Research	eleanor maguire et al 2000
	studied brains of london taxi drivers using an mri scanner
	learning has caused structural changes
	increase volume of grey matter in the hippocampus
	hippocampus is associated with spatial and navigational skills
	longer job greater difference
functional recovery	a type of plasticity
	brain transfers functions of damaged areas to undamaged areas
How ?	rewire and reorganise itself
	forming new synaptic connections close to the damaged area
	axon sprouting

Hint	Answer
	reformation of blood vessels
	recruitment of homologous areas
Evaluation 1	kuhn et al 2014 plasticity
	video games for 30 minutes
2	plasticity negative behavioural consequences
	drug use leads to poorer cognitive function
	phantom limb syndrome due to cortical reorganisation
3	taijiri et al 2013 functional recovery
	provided stem cells to rats
4	practical applications
	neurorehabilitation which uses motor therapy and electrical simulation of the brain to counter negative effects
	constraint induced movement therapy
5	age differences
	elbert et al capacity for neural reorganisation is much greater in children
