What is the role of dopamine in the pleasure/reward pathway?

Dopamine in the pleasure/ reward pathway strengthens synapses and sends signals.

Dopamine is a neurotransmitter that plays a crucial role in the brain's pleasure and reward system. It is released during pleasurable situations, stimulating one to seek out the pleasurable activity or situation again. This is due to the fact that dopamine strengthens the synapses, which are the connections between neurons, and sends signals throughout the brain. This pathway is often referred to as the "pleasure/reward pathway" because it is associated with feelings of pleasure and reward.
