Dopamine

Today at a presentation about "Positive Teams", the term "Dopamine" was raised by the presenter. The Presenter claimed that in terms of reward, dopamine plays an important role. For example, if an employee did a good thing, and the manager managed to reward him to a level where the dupamine level went up, the employee would continue enjoying that acttion because its pleasurable to get the reward after it. He also said, that sometimes you see a person attached to another person without clear explanation, it could mean that the other person did something that raised the dupamine level in the guy and he started getting attached for him to feel the pleasure again.

Here is some scientific explanation I found on the net:

'Scientists probed further to see if they could link the brain's reward systems to a particular set of chemical mechanisms. They soon found that blocking the neurotransmitter dopamine seems to reduce an animal's pleasure-seeking drives. For example, depleting dopamine in the brain causes animals to become oblivious to food and other normally pleasurable rewards. Rats with such lesions will starve to death unless force-fed. They retain the ability to find the food, chew, and swallow, but they seem to lose all desire to eat, even when the food is placed right under their noses. Scientists also found that the rat hypothalamus produced more dopamine when the rats were engaged in pleasurable activities, suggesting that dopamine was indeed closely linked to pleasure and reward."Focus on Dupamine

I found that intresting because, sometimes we feel comfortable or happy around some people without knowing the reason behind that .. Some activities give us great pleasure without explainging why! Could it be that Dupamine is involved here??

The brain is such an intresting area .. Sub7an Allah!!
