home health pessimistic thinking are induced by an area of the brain, say scientists photo / theculturemastery United States. Researchers of the technological Institute of Massachusetts (MIT), have found an area of the brain that controls the pessimistic reactions thanks to an experiment with rhesus monkeys through artificial stimulation. Experts say that the persistent thoughts which lead to negative decisions may be symptoms of mood and anxiety disorders.
The research, published in the scientific journal Neuron, revealed that in experiments, macaques would become pessimistic reactions stimulate the caudate nucleus with a small electric shock at the moment in which the animal had to choose between two offers proposed by experts: a reward (juice) or an unpleasant experience (a blast of air in the face).
After stimulation in that area of the brain, scientists at MIT found that they increased cases of primates that are decided for the latter. “We found that this microestimulacion was irrationally repeated elections with negative assessments,” they explain.
Now, the study aims to apply to humans to verify if they also lean toward the negative option. “We are so delicately balanced that only with a little ‘disconnect’ system you can quickly change the behavior,” highlights the researcher Ann Gabryel.
