Brain Plasticity Validation

what does an MRI produce

still images

what does MRI stand for

Magnetic resonance imaging

how does an MRI work

it uses a strong magnetic field and radio waves to produce pictures of the brain

what are two strengths

it is non-invasive and it gives more detailed pictures than those produced by a CT scan

what are two limitations

cannot have a pacemaker or any metal in or on the body and some machine produce loud noises which could cause distress

What is the role of the hippocampus

to facilitate spatial memory, learning and emotion

what is proliferation

the rapid increase in the number of early-stage brain cells (neural precursor cells) through cell division

what is migration

the movement of immature neurons from their birthplace to their final destination within the developing brain

what is circuit formation

the brain's ability to reorganize and create new neural pathways and connections (circuits) through experience and learning

what is synaptic pruning

the process where the brain eliminates extra neurons and synapses

what is myelination

the process of forming and modifying myelin sheaths around axons - makes thicker nerve fibres
