多巴胺

每天運動有助分泌多巴胺
今天打球 對手那堵牆相當強勁
汗滴到眼睛裡  真痛!真暢快

我愛上了黃點點球
藍點點 實在太彈了

啊  每天都可以打球  多棒啊

wikipedia 對dopamine有相當完整的解釋
這真是一個太有趣的東西了!
好好學習dopamine的知識,相信在情場上無往不利啊!

Dopamine is a hormone and neurotransmitter occurring in a wide variety of animals, including both vertebrates and invertebrates. In chemical structure, it is a phenethylamine. Dopamine has many functions in the brain, including important roles in behavior and cognition, motor activity, motivation and reward, regulation of milk production, sleep, mood, attention, and learning.

The phasic responses of dopamine neurons are observed when an unexpected reward is presented. These responses transfer to the onset of a conditioned stimulus after repeated pairings with the reward. Further, dopamine neurons are depressed when the expected reward is omitted. Thus, dopamine neurons seem to encode the prediction error of rewarding outcomes. In nature, we learn to repeat behaviors that lead to maximize rewards. Dopamine is therefore believed to provide a teaching signal to parts of the brain responsible for acquiring new behavior. Temporal difference learning provides a computational model describing how the prediction error of dopamine neurons is used as a teaching signal.

In insects, a similar reward system exists, using octopamine, a chemical relative of dopamine
