ch 6 cognotive development Flashcards
neuroplasticity
the ability to develop and change in response to the enviornment
synaptic growth
the most significant in the first year of life but it continues during childhood and into adolescence
neural connections
grow in size and complexity after birth and myelination (covering the neuron with myelin white matter) is accelerated
brain plasticity
the brain’s ability to modify and make new neural pathways
development plasticity
the development and consolidation of new neural pathways in infants, children and adolescents
adaptive platicity
the ability of the brain to change, adapt and grow throughout life
5 stages of development
- proliferation
- migration
- circuit formation
- synaptic pruning
- myelination
proliferation
first stage of nervous system developing during which the cless of the foetus divide and multiply
migration
the movement of newly formed neurons to their destines location
circuit formation
the axons of the new neurons grow out to targer cells and form new synapses
synaptic pruning
excess neurons and synapses as well as weak connections are eliminated
mylelination
the formation of myelin over the neurons. Myelin is a white, fatty waxy substance that coats some axons and protects them. FInal stage before brain fully mature
cerebellum
increase in the number of neurons and synapses. Responsible for balance, muscle tone and motor skills
amygdala
becomes more active. Responsible for emotions, survival instincts and memory
corpus collosum
thickens and increases in the number of connections between hemispheres
