The reward system of the brain
Brain biochemistry significantly raises good enjoyed pleasures. One major form is dopamine. It functions as a neuro transmitter chemical released by brain cells to send signals to other brain cells. The human brain uses five known types of dopamine receptors. Dopamine plays a major role in our brains, responsible for reward-driven learning. Every studied type of reward increases the level of dopamine transmission within the brain . Dopamine provides an effective teaching signal to parts of the brain responsible for new behaviors.
