According to Wolfe (2010), neurons, which cannot be reproduced, received process and send the information. The neurons contain thousands of threadlike branches, also known as dendrites, which reach to other neurons. At the end of each branch of the neurons, there is a small gap or synapse. When an electrical message travels through the neuron and reaches the end of a dendrite, it releases a chemical substance that transmits nerve impulses across a synapse which is then picked up by a receptor from a different neuron. Since receptors are designed to collect only one kind of neurotransmitter, new dendrites are continually developing, strengthening neuronal pathways and enabling them to become more efficient.
