Psychophysiological mechanisms of cognition disorders and optimization of their correction: I. Psychophysiological effects of transcranial micropolarization used as a corrective therapy for different disturbances in the control of wakefulness, emotions, and cognition in schoolchildren aged 10–12 years with learning difficulties

We have summarized the results of psychophysiological studies in schoolchildren aged 10–12 years with cerebral functional disturbances of hypoxic-ischemic or traumatic origin with learning difficulties. We have differentiated three types of disintegration of ultraslow information-controlling systems that reflect specific disturbances in the interaction of cortical-brainstem, limbic-reticular, and suprasegmental mechanisms of regulation of the wakefulness level and are characterized by emotional and cognitive disturbances typical of each type of disintegration. Adolescents with moderately and strongly decreased resistance to transitory hypoxia differed in psychological and psychophysiological effects of corrective and recovery therapy, which included transcranial micropolarization (TCMP) and psychological-pedagogical sessions during and between TCMP sessions and during the intervals between repeated TCMP courses. We discuss the psychophysiological mechanisms of the corrective effect of low-intensity direct currents with parameters close to the native ultraslow processes of the brain and the body systems regulated by these parameters.
