Document Summary

Norm: an average or standard, measurement calculated from the measurements of many individuals within a specific group or population. Head-sparing: a biological mechanism that protects the brain when malnutrition disrupts body growth. The brain is the last part of the body to be damaged by malnutrition. Neuron: one of billions of nerve cells in the central nervous system, especially in the brain. Cortex: the outer layers of the brain in humans and other mammals. Most thinking, feeling, and sensing involve the cortex. Prefrontal cortex: the area of the cortex at the very front of the brain that specializes in anticipation, planning, and impulse control. Axon: a fibre that extends from a neuron and transmits electrochemical impulses from that neuron to the dendrites of other neurons. Dendrite: a fibre that extends from a neuron and receives electrochemical impulses transmitted from other neurons via axons. Synapse: the intersection between the axon of one neuron and the dendrites of other neurons.
