Today, neuroscience specialists from the University of Plymouth presented the results of their new and interesting research on low-frequency ultrasound as the most accessible and effective tool for changing the brain's work – in particular, for changing some specific thinking and decision-making processes. Their study was based on the experimental effect of ultrasound on the brain of experimental monkeys, which was reflected in the very alternative way of making decisions on their part when they were exposed to one or another stressful situation in the laboratory.
Previously, experts noticed that the crown of the brain is the center from which the neural activities associated with the decision-making process come – but they also tried to find out how much you can influence these processes by affecting this region of the cerebral cortex with ultrasound. frequencies. Because despite the discovery of such a center, the experts, nevertheless, did not find the specific area of the brain responsible for this process.
Having conducted several experiments on experimental monkeys, experts noticed that exposure to low-frequency ultrasound actually causes an alternative reaction of neuron activity in the waist cortices of the brain – which implies the adoption of alternative and not always logic-justified decisions by monkeys. In addition, the study also addressed some other issues related to the transformation of neural connections and neural activity, depending on a particular area of the brain.
It is worth noting that the monkey brain changed by low-frequency ultrasound also began to show some other foci of activity – for example, using more regions of the posterior cortex. This can potentially indicate that during exposure to low-frequency ultrasound, the brain tends to seek help from related areas of the brain.
