Psychology of the Human Brain PP

The structure of the human brain is one of the most complex organs in the body that is continuously researched for a deeper understanding of its function. Communication within the brain occurs between numerous neurons that transmit messages electrically within a neuron and chemically between neurons. Messages travel down a neuron from the dendrites that receive a message and then through the axon towards the synaptic cleft where the chemicals are dispensed. The synaptic cleft is a designated area for chemicals to be released from a neuron and transmitted to the next. Chemicals bind to the corresponding receptors of the upcoming neuron to be stimulated and continue its path throughout the brain. Chemicals such as serotonin and dopamine are transmitted throughout the brain via neurons. Serotonin relates to sleep, eating, and mood, which are critical for human well-being.
