Нейрофизиологические корреляты принятия решений в условиях рискаNeurophysiological Correlates of Risky Decision-making

Using electroencephalogram (EEG) and transcranial alternating current stimulation (tACS), our research team sought to identify a neural signature associated with risky decision making. Initially, we aimed at stimulating a network associated with risky decision making by stimulating the left and right frontal hemisphere with various frequencies. We discovered that 20 Hz stimulation applied to the left frontal hemisphere increased participants choice to select risky options. We then aimed to confirm our findings with time-frequency analysis using EEG. In this experiment, not only did we confirm the neural signature of risky decision making, it appears that 20 Hz (or beta rhythm) may account for a learning mechanism between decisions.
