There are over 100 billion neurons in the brain and billions more throughout the body. The neurons receive and transmit information to the brain. The dendrite picks up information from other neurons and transmits these messages to other neurons that send that information to the cell body. The axon varies in size depending on the location in the body and carries outgoing messages to muscles and glands. All neuron information is transmitted to the spinal cord then to the brain. Dopamine helps with motor control and coordination and is also responsible for behavior and emotions. It is believed that the incorrect amount of dopamine in neurons can cause the development of Parkinson’s disease. Serotonin helps with regulation of sleep, eating, pain, mood, dreaming and aggressive behavior.
