Ocular Influence of Nano-Modified Fullerene Light, 2: Time Correlation of the Choice and Simple Sensorimotor Reactions That Determine Blinding Compensation of the Driver We studied the ocular effect of light converted by fullerene on the dynamics of a simple sensorimotor reaction, a reaction of choice (CR) and their correlation at the background of recording the electrical activity of the human brain under extreme lighting conditions and inadequate visibility of the object. We examined 17 people (170 surveys of 8 men and 9 women) aged from 18 to 22 years without health complaints, according to the requirements of ethics when working with people. The ocular pathway of light exposure was provided by the use of glasses with fullerene (C 60 ) filters (Tesla Hyperlight Eyewear ) with 0.33 concentration of fullerene in polymethyl methacrylate organic glass, 2 mm thick. For a placebo, we used glasses in a similar frame with a filter similar in light range, but not containing fullerene. The experimental model reflected the standard situation in which the driver of a vehicle falls in blindingly bright light. We determined the latent periods of a simple sensorimotor reaction and a CR. Electroencephalography (EEG) was recorded with eyes closed and open, with glasses with a fullerene nano-filter and a placebo filter. The Neuron-Spectrum-4/VP (NeuroSoft) complex was used. The recording was carried out mono-polarly, with a quantization frequency of 500 Hz, the electrodes were arranged according to the international system 10-20 in 19 leads. In each lead for the frequency ranges of EEG-delta (0.5-3.9 Hz), theta (4.0-7.9 Hz), alpha (8.0-12.9 Hz), beta1 (13.0-19.9 Hz) and beta2 (20.0-35.0 Hz) in the Neuron-Spectrum program, power spectral density (PSD) was calculated. We revealed a decrease in correlation of the latent periods of a simple sensorimotor reaction and the CR when using light modified by fullerene. This indicates an improvement in the rate of inter-hemispheric information processes and improvement in the quality and effectiveness of decisions made. It was found a significant (significant) decrease in the activity of frontal and central zones of the right hemisphere in the delta and beta2 ranges. This indicates a decrease in tension during identification of the stimulus and weakening of the activity of image processing operations, i.e. developing a less stressful state and facilitating the decision-making process. It was evidenced a significant increase in the activity of Posterior cingulate cortex in the theta and alpha ranges. This indicates improved coordination of visual information, attention, assessment of the position of the body, inhibition of irrelevant information and optimization of decision-making processes. The result of these changes was an increase in the speed of central information processing and a shift in focus from image processing to decision-making processes.
