Expert Solution
Step 1: Introducing neurotransmitter:

A neurotransmitter is a chemical messenger in the brain that transmits signals between nerve cells, or neurons. These molecules are vital for proper brain function, playing a role in various physiological and psychological processes. Neurotransmitters control mood, memory, muscle movement, and many other essential functions by allowing communication between different parts of the nervous system. Dopamine, for instance, regulates motivation and pleasure, while serotonin influences mood and sleep patterns. Neurotransmitters can be found throughout the brain, and their precise balance is crucial for maintaining mental and physical well-being. Dysregulation of these neurotransmitters is often associated with various neurological and psychiatric disorders.
