(what undergoes a period of exuberance?)
formation of connections between neurons
synaptogenesis
period of rapid neural growth
synaptic blooming
neural connections are reduced
synaptic pruning
coating of fatty tissues around the axon of the neuron
myelin
insulates the nerve cell and transmission speed of impulses from one cell to another
myelin
enhances the building of neural pathways
myelin
thin outer covering of the brain involved in voluntary activity and thinking
cortex
where most of the neural activity occurs
cortex
behind the forehead; for thinking, planning, memory, and judgement
frontal lobe
responsible for processing info about touch; extends from the middle to the back of the skull
pariental lobe
back of the skull; processes visual information
occipital lobe
responsible for hearing and language; between the ears
temporal lobe
process in which different functions become localized primarily on one side of the brain
lateralization
for language production
left hemisphere
for visuospatial ability tasks

sucking
turning the head when the cheek is touched
rooting
fingerd automatically grip anything that touches the paln of the hand
grasp
toes will fan out and curl when the sole of the foot is stroked

moro
infants will extend the arm and leg on the side while flexing the limbs on the opposite side

legs move in stepping-like motion when feet touch a smooth surface
stepping
involuntary movements in response to stimulation
reflex
head to tail

from the midline outward
proximodistal
walking while holding onto something
cruising
ability to move our bodies and manipulate objects
motor skills
focus on the muscles in our fingers, toes, and eyes, and enable coordination of small actions

grasping an object with fingers and palm but no thumbs
palmer grasp
grasp with forefinger and thumbs
pincer grasp
