BRAIN DEVELOPMENT, DAMAGE & NEURO-PLASTICITY - Coggle Diagram
BRAIN DEVELOPMENT, DAMAGE & NEURO-PLASTICITY
growth of the maturing brain
human CNS form when embryo is 2 weeks old
cerebrospinal fluid
central canal of spinal cord
4 ventricles of brain
birth, brain weigh 350g, adult brain 1200g - 1400g
development of neurons in brain
proliferation
migration
differentation
myelination
synaptogenesis
stem cells
facilitate learning
differentiation of cortex
neurons in different parts of brain
differ from one another in shape & chemical components
neurons transplanted at later stage
develop new properties but retain some old ones
fine-tuning by experience
brain has limited ability to reorganise itself in response to experience
gain & loss of spines indicate new connections, relates to learning
brain can't be exercised like a muslce
practicing a skill reorganises brain to maximise performance of that skill
brain & behavioral development
adolescents are more impulsive than adults
can be a problem
leads to
risky driving
drinking
sex
not equally impulsive in all situations
antisaccade task
looking away from powerful attention-getter
