[Auditory sensory support of complicated voluntary goal-aimed bimanual movements].

The intrasensory and sensor-effector interactions between inter-spike intervals of acoustic stem-evoked potentials with parameters of hands coordination was found with the help of correlation analysis. Role of excitation of ascending fibres of rostral part of the pons and lateral loop in mechanisms of the auditory-motor coordination was determined. Sex-dependent differences in integration of elements of the sensor-motor system because of lateralization of incoming auditory information and complication of the motor task performed were revealed. In men, mechanisms of auditory-motor coordination have less determined character than in women. That probably determines higher level of bi-manual coordination in men. Optimal correct realization of motor program in men is performed prognostically, while in women--after a mistake has been done.
