Neurons nerve cells, which are the nervous system"s basic units. Myelination the process by which the axon portion of the neuron becomes covered and insulated with a layer of fat cells, which increases the speed and efficiency of information processing in the nervous system. Synapses gaps between the neurons, where connections between the axon and dendrites occur. Corpus callosum a large bundle of axon fibers that connect the brain"s left and right hemisphere. Prefrontal cortex the highest level of the brain"s frontal lobes that is involved with reasoning, decision making, and self-control. Amygdala a portion of the brain"s limbic system that is the seat of emotions. In childhood and adolescence, the brain has a remarkable ability of being able to repair itself.
