Today, neuroscience experts from the University of Plymouth presented the results of their interesting new study on low-frequency ultrasound as the most affordable and effective tool for changing brain function – in particular, for changing some specific processes of thinking and decision making. Their study was based on the experimental action of ultrasound on the brain of experimental monkeys, which was expressed in the very alternative way of making decisions on their part, when they were exposed to certain stressful situations in the laboratory.
Previously, experts noticed that it was the cortex of the brain that is the center from which the neural activities associated with the decision-making process come from – however, they also tried to find out how much they can influence these processes by acting on this part of the cerebral cortex with low frequencies. Because, despite the discovery of such a center, specialists, nevertheless, did not find the specific area of the brain responsible for this process.
After conducting several experiments on experimental monkeys, experts noticed that exposure to them with low-frequency ultrasound actually causes an alternative reaction of neuron activity in the cingulate cortex of the brain – which implies the fact that monkeys make alternative and not always justified from the point of view of logic decisions. In addition, the study also raised some other issues related to the transformation of neural connections and neural activity depending on a particular part of the brain.
It is worth noting that the monkey brain changed through low-frequency ultrasound also began to show some other foci of activity – for example, involving more regions of the posterior cortex. This could potentially indicate that during exposure to low frequency ultrasound, the brain seeks to seek help from related areas of the brain.
