Material
Weight triples by what age - ✔✔1 year old
Light Sleep - ✔✔awakened easily, eyes move slowly, muscle activity slows, sudden muscle
contractions
Eye movement stops - ✔✔Brain waves slower; body temperature drop, heart rate slows
Deep Sleep - ✔✔extremely slow brain waves, talk during one's sleep, bed wetting
REM - ✔✔90 minuted after falling sleep; heart rate and breathing quickens; intense dreams
Brain Development - ✔✔brain contain most of the neurons it will ever have at birth
Neuron - ✔✔the nerve cells that transfer information
Dendrite - ✔✔the protruding branch of a neuron. it receives information from other cells
Axon - ✔✔the main protruding branch of a neuron it carries information to other cells
Myelin - ✔✔insulating material that forms a sheath around the axon and speeds the
transmission of information
Synapse - ✔✔the gap between neurons
, Neurotransmitter - ✔✔a chemical generated by a neuron sending information across the
synapse
Synaptogenesis - ✔✔the formation of new synapses
Cerebral Cortex - ✔✔brains outer most layer; processing center for the perception of patterns,
the execution of complex motor sequences, planning, decision making and speech
Experience-expectant process - ✔✔under genetic controls, occur in any environment
Experience-dependent process - ✔✔initiated in response to experience
Synaptic pruning - ✔✔use it or lose it
Frontal lobe - ✔✔ability to concentrate, judgement, analysis, problem solving
Parietal lobe - ✔✔integrate information from several senses, speech, pain & touch
Occipital lobe - ✔✔visual processing center of the brain
Cerebellum - ✔✔attention & language
Brainstem - ✔✔basic function such as breathing and heart rate
Temporal lobe - ✔✔high level visual processing
