Physiological estimation of the resultant activity of schoolchildren working on a computer


, : Physiological estimation of the resultant activity of schoolchildren working on a computer. Vestnik Rossiiskoi Akademii Meditsinskikh Nauk 0(11): 47-52

The schoolchildren who had achieved high results in computer learning tasks showed a regular nature of changes in autonomic parameters, which was in concordance with steps taken in goal-oriented activity. Those with low results displayed higher and disconcorded changes in autonomic parameters, which were interpreted as a predisposition to emotional stress when learning computer tasks. The high-result schoolchildren made fewer errors in reaction-time tasks and signal differential tasks and spent less time in decision-making. They also differed from low-result schoolchildren by showing a higher frequency of beta-rhythm ECCG from forehead derivations and prevalent alpha-rhythm and also a higher proportion of theta-rhythm in the spectra of the forehead, central and parietal derivations as well as a higher coherency of alpha-rhythm from the forehead and parietal derivations of the left hemisphere.

During intracranial EEG (icEEG) monitoring the likelihood of observing a seizure is increased by tapering anti-epileptic drugs (AEDs). Presumably AED taper results in an increase in cortical excitation which in turn promotes seizure emergence. We...
