Nature:
Nature/nurture?
Inherited genes play role in a person's behaviour.
Behaviour and genes? Not all of these genes are expressed but the observable characteristics expressed by them are
known as phenotypes.
Brain development? Genotype is the inherited genetic material that a child gets from their parents. These aren't always
expressed.
Physical growth and development? Nurture/environment:
Everything else beyond genes and biology.
Epigenetics: change in the expression of genes altered by the environment one encounters.
Methylation: silencing of certain gene expression caused by epigenetics.
Brain development:
Sensory input of one side of the body goes to the opposite hemisphere of the brain.
Cerebral lateralization: using different hemispheres to process different modes.
Corpus collosum: thick nerve fibres that allows two hemisphere of the brain to communicate.
Synaptogenesis: process by which neurons form synapses with other neurons.
Synaptic pruning (synapse elimination): synapses that aren't as much used, are eliminated.
Brain is capable of being modeled or changed by experiences: experience-expectant plasticity:
general human experience sharping the brain., experience-dependant plasticity: experiences
throughout life reorganizes and creates new neural connections.
