But the connection that scientists are making are saying basically this: when you check your information, when you get a buzz in your pocket, when you hear a ring you get what they call a dopamine squirt.
For the first time, researchers have defined this phenomenon, which they call dopamine agonist withdrawal syndrome, or DAWS.
God loves us do we were given built in dopamine and endorphins to experience God.
Neuroscientists know that dopamine is important in both systems -- learning and pleasure -- but haven't yet worked out the explicit tie between them.
Neuropsychologists have discovered that high levels of certain dopamine strains (D5 I believe) cause women to assume sexually receptive postures.
The real strength of their invention and insight comes out of the fact that dopamine is a very reactive molecule.
It binds here, releases a hormone known as dopamine, and that makes people feel good.
Natural increases in dopamine occur after unexpected natural rewards; however, with learning these increases shift from the time of reward delivery to cueing stimuli.
Cocaine and other addictive drugs, however, produce a momentary increase in dopamine through neuropharmacological mechanisms, thereby continuing to drive learning, forcing the brain to over-select choices which lead to getting drugs.
Owning pets, playing musical instruments, being part of a family, having a job, etc. are all activities that relate to long-term dopamine production.
