The Pleasure-pain Balance

Dopamine is a brain chemical involved in reward processing. It plays a role in motivating people to get a reward.

A genetically engineered mouse that was unable to release dopamine didn’t seek food and starved to death. But when food is directly put in their mouth, they chew it.

  • Pleasure and pain are co-related
  • Pleasure and pain are processed in overlapping brain regions.
  • Pain and pleasure are self-regulatory. When the balance tips to one side, the self-regulating mechanism comes into action to bring it back to the same level.
