Dopamine: Supports feelings of reward and motivation. More Dopamine is produced in anticipation of something good.

Serotonin: Helps maintain emotions. This is why antidepressants (SSRI and SNRI) are designed to balance out serotonin levels.

Oxytocin: The “love” hormone, gives you a rush of pleasure from affection and connection.

Endorphins: A surge of pleasure, often in response to occasional discomfort or stress. Endorphins are endogenous opioids, so they bind to the opioid receptors. The runners high is thought to be as a result of a release of endorphins after a hard run.

Those descriptions are way too simplistic. Parkinson's is caused by a loss of dopaminergic neurons, but has little to do with reward signaling, it's a degeneration of the motor system.

Yeah the explanation above is not even covering the basics. For example oxytocin's primary function is to facilitate childbirth. Dopamine is involved in motor control. Serotonin regulates a number of functions such as cardiovascular.
