reward-seeking

A much larger body of research has identified a role for dopamine in reward-seeking behaviors in general.

Dopamine is a brain chemical associated with pleasure and reward-seeking behavior; it also controls muscle movements.

This research uncovers the brain circuitry responsible for self-control during reward-seeking choices.

This large response might energize reward-seeking behaviors and counteract the sedative effects of alcohol.

So we looked for genetic markers associated with dopamine, which modulates risk-taking and reward-seeking behaviors.

The neurotransmitter dopamine, which helps transmit signals between nerve cells, is linked to reward-seeking behaviour.

Steinberg says it's a lot harder to change the reward-seeking predilections of teenagers than to restructure the environment in a safer way.

Looking through wanted notices later on, he had picked out George and a reward-seeking Sheriff had got in touch with Jack Clarke.

The reward-seeking brains of teens may lead them to experiment with pleasure-inducing substances like drugs and alcohol, which are especially dangerous for this age group, scientists say.

The outsize reward-seeking tendencies of the hopelessly ­outer-directed helped bring us the bank meltdown of 2008 as well as disasters like Enron, she claims.

Over time this reward-seeking behavior will increase synaptic plasticity, resulting in an increase in neuronal connections and faster response times.

While dopamine is involved with both the motor and reward systems, it is unclear why some Parkinson's patients exhibit reward-seeking behavior, particularly when taking dopaminergic drugs.

Addiction causes molecular changes in the brain, most notably in the regions that release dopamine, a messenger molecule involved in reward-seeking behaviours.

Additionally, the enzyme TTTan aromatase, which functions in the male brain to convert testosterone to estradiols, has been linked to addictive and reward-seeking behaviors.

The World Debit MasterCard card is designed to maximize the benefits realized by high-spend and reward-seeking consumers who choose debit as their method of payment.

For companies, the premise of gamification is that it engages people in the kind of reward-seeking behaviors that lead to increased brand loyalty, not to mention increased profits.

In one paper published last year, brain scans of subjects seeking first-time treatment for depression showed especially weak links between the default mode network and a region involved in motivation and reward-seeking behavior.

Finance chief Ivan Rios' severed hand was delivered by the reward-seeking bodyguard who killed him, and rebel patriarch Manuel Marulanda died of a heart attack on March 26 at age 78.

However, the APA said there is a possibility that a group of reward-seeking behavioral disorders—including video game addiction and Internet addiction—will be included in an appendix of DSM-5 to "encourage further study."

Researchers also find that the brains of overeaters and those with substance addictions share a common shortage of receptors for the neurotransmitter dopamine, a key chemical in the activation of reward-seeking brain circuits.

The study helps explain a distinctly human mechanism of cognition, said the lead researchers at Brown University, and could be applied to studying and treating reward-seeking or punishment-avoidance conditions such as addiction or obsessive-compulsive disorder.

Then, last summer, a reward-seeking antiques dealer with an epic-length criminal record suddenly fired up new hopes for recovery of the art by announcing that he could "facilitate" it in exchange for the $5 million the museum has offered.

By offering World Debit MasterCard to its customers, Fifth Third Bank is now providing a custom-tailored debit product that meets the unique, everyday spending needs of its high-spend and reward-seeking debit cardholders.

In this way, serotonin may facilitate the expectation of reward at a quasi-emotional level, and thus either encourage or discourage persistence in reward-seeking behaviour depending on the demand of the task, and the duration of persistence required.

The findings suggest that individuals with antisocial personality disorder may not be unaware of or simply dismissive of consequences, Buckholtz indicates, but instead that their intense reward-seeking motivation consumes their attention wholly until they have fulfilled their desire for reward.
