Document Summary
Where should babies sleep? some babies are separated from parents while sleeping: bed vs crib/ together. Prenatal and postnatal brain growth (head circumference) is crucial for later cognition. Head sparing is a biological mechanism that protects the brain when malnutrition. The brain is the last part of the body to be damaged by malnutrition. Cortex: outer layers of the brain where thinking, feeling, and sensing occurs. Prefrontal cortex: area of cortex at the front of the brain that manages anticipation, planning, and impulse control. Neurons: one of billion nerve cells in the cns. Axons: fibers that extend from neurons and transmit impulses from neuron to dendrites of other neurons. Dendrites: fibers extending from neurons that receives impulses from other neurons via axons another neuron. Synapses: intersection between the axon of one neuron and the dendrites of. Neurotransmitter: brain chemical that carries info from axon of a sending neuron to dendrites of receiving neuron.
