List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction

The brain is an amazing arrangement. It is the most rigid and interesting part of the human body. It is like a computer that controls every part of the body. The brain consist of many millions of neurons cells that support the brain system this is called Glial cells (Pinel 2011 p.55) The neurons in the brain process information and these are the nervous system communication device. Neurons can be broken down into four structures. These are soma‚ the cell body which shields and protect the nucleus

fact too many‚ and so pruning takes place thereafter in which unnecessary connections are severed. Myelinization of the reticular formation‚ amygdala‚ and hippocampus begin during infancy as well. Myelinization is the formation of sheaths on the axons of neuron which increases nerve conductivity and nerve conductivity velocity. Specifically‚ the myelinization of the reticular formation helps increase an infant’s ability to concentrate on a single task and relegate other automated tasks to extra-attentional
