Adaptive Control of an Operator's Performance Based on Biological Feedback Using the Parameters of Spatial Synchronization of Brain Cortex Areas

摘要

The efficiency of an operator's performance under the determined (D-activity) and stochastic (S-activity) conditions depends on the readiness and synchronization of the frontoparietal and parietooccipital brain cortex areas. The algorithm for the generation of the feedback signal and program of adaptive control based on parameters of these cortical areas' spatial synchronization were developed. To develop the adaptive control based on this algorithm, two series of experiments on volunteers were performed. The results of the study showed a connection between the initial readiness estimated by Luscher's test and the efficiency of S-and D-activities modeled by computer games. The objective signs of initial readiness for S- and D-activity were found using parameters of spatial synchronization of the studied cortical areas' activity in different spectral bands. The possibility of developing adaptive control skills based on the algorithm of the feedback signal generation and maintenance of these skills for one month was also demonstrated. Adaptive control sessions were found to improve characteristics of S- and D-activity, modeled by computer games.
