Pleasure region of the brain

Did you know that when you make a donation to charity, your brain acts in a similar way to when you are having sex or eating chocolate? It's true. Thanks to fMRI technology, researchers are able to see brain activity when certain acts are taken and in a study on charitable giving when people donated to a worthy cause, the midbrain region of the brain lit up. This is the area of the brain that is responsible for our cravings food and sex and pleasure rewards, showing the link between charitable giving and pleasure Note: To my knowledge no study has been done looking at our brain activity when we have sex AND eat chocolate so I can't say that giving to charity is similar to doing both at the same time. Although, I'm personally volunteering for that study in case you are a researcher who wants to look into this further. This reward or pleasure response to giving is the physiological reason behind the 'warm glow' or that good feeling you get when you give and why you may choose to spend money on others or charity compared to yourself.

The finding, published in the October 18 issue of the Journal of Neuroscience, may help explain why people are more likely to acquire a drug addiction during times of intense stress in their lives. It may also yield clues to why some, but not other chronic pain patients may be prone to developing addictions to certain pain medications. The study, which involved 25 healthy men and women, showed that dopamine was active in areas of the brain region known as the basal ganglia, the same region where it has been observed to respond to positive stimuli, such as food or sex. That effect persisted even after the researchers controlled for the negative emotional effects caused by the actual research setup, which included a needle inserted into a large jaw muscle, and the expectation of pain and repeated questioning. The authors concluded that in some areas of the basal ganglia, dopamine was involved in the assessment of pain itself, while in the ventral area, or nucleus accumbens, it was related to the emotional experience of pain.

Electrical stimulation in cats of regions in and related to the anterior part of the hypothalamus can induce the behaviour of expelling or retaining urine and feces. When electrodes planted in these regions are stimulated by radio waves, the cat stops whatever it is doing and behaves as though it is going to urinate or defecate. It goes through its usual behaviour of digging a hole, squatting, and assuming the correct posture, and then it passes urine or feces. At the end, it even goes through its customary ritual of hiding its excreta.
