neurotransmitter -
☑️ a brain chemical that carries information from the axon of a sending neuron to the
dendrites of a receiving neuron
prefrontal cortex -
☑️ the area of the cortex at the front of the brain that specializes in anticipation, planning,
and impulse control
shaken baby syndrome -
☑️ a life-threatening injury that occurs when an infant is forcefully shaken back and forth, a

gross motor skills -
☑️ physical abilities involving large body movements, such as walking and jumping.
, fine motor skills -
☑️ physical abilities involving small body movements, especially of the hands and fingers,
such as drawing and picking up a coin
sensation -
☑️ the response of a sensory system (eyes, skin, tongue, nose) when it detects a stimulus
perception -
☑️ the mental processing of sensory information when the brain interprets a sensation
binocular vison -
☑️ the ability to focus the two eyes in a coordinated manner in order to see one image
immunization (inoculation or vaccination) -
☑️ a process that stimulates the body's immune system to defend against attack by a

co-sleeping (bed-sharing) -
☑️ a custom in which parents and their children (usually infants) sleep together in the same

sensorimotor intelligence -
☑️ Piaget's term for the way infants think-by using their senses and motor skills- during the
first period of cognitive development
assimilation -
☑️ Piaget's term for a type of adaptation in which new experiences are interrupted to fit into,
or assimilate with, old ideas
accommodation -
☑️ Piaget's term for a type of adaption in which old ideas are restructured to include, or

"little scientist" -
