Question

How are neurotransmitters linked to human behavior? Give two examples.

Answer 1

Neurotransmitters are released from the neurons present in the brain. The neurons consist of axons and cyton. There are outward projections which are called as the dendrites which transfer the stimulus from one cell to another across the neuro-muscular junctions. These neuromuscular junctions are connected to the muscles for the transfer of information from one cell to another in the different brain regions. The examples include that of the Acetylcholine which is released from the neurons. The role of it to regulate the voluntary movement and locomotion, sleep and learning. The release of dopamine is associated with the process of learning and memory as the signal waves are transmitted in the neurons in the form of wave polarization signal channels. The levels of dopamine regulate brain reward and the thinking of sexual behavior in a person. The release of norepinephrine is related to the eating and the level of alertness in different regions of the brain. These neurotransmitters regulate the behavior of a person depending upon the amount of signal which is released from the brain in the form of chemical which is released across the membrane junctions of neurons. The low levels of norepinephrine cause depression in the brain. The release of neurotransmitter is associated with mood, sleep alterations, aggression and impulsive behavior in a person. The effect of endorphins is to relieve pain present in the different regions of brain.
