Working memory is one of the key functions for mental activity. In this work, behavioral and hemodynamic parameters during mnestic activity were studied. N-back tests for working memory were performed with simultaneous recording of the rheoencephalogram (REG) in the basins of the left and right internal carotid and vertebral arteries. The dynamics of REG showed a decrease in blood filling, an increase in vascular tone and difficulty in venous outflow during mnestic activity. Short-term adaptation of cerebral circulation during mnestic activity was accompanied by changes in arterial inflow, venous outflow, as well as the tone of distribution vessels and resistance vessels in the frontal-parietal regions. Optimal and non-optimal typological characteristics of cerebral circulation and features of regulation of cerebral vascular tone during mnestic activity are discussed.
