Аннотация


Было проведено исследование нейрональных сетей сенсомоторной системы семи здоровых добровольцев при выполнении активных и пассивных движений правым и левым указательным пальцем в заданном темпе методом функциональной МРТ (фМРТ). При обработке полученных данных для обеих парадигм было выявлено доминирование активации первичной сенсомоторной, премоторной, дополнительной моторной коры, вторичных сенсорных зон на стороне, противоположной движению, а также активации в полушарии мозжечка, соответствующем стороне движения. Было показано совпадение зон региональной активации, а также объема активации, амплитуды и координат вокселов с максимальными значениями в первичной моторной и сенсорной коре. Полученные данные позволяют использовать пассивные движения наряду с активными для исследования сенсомоторной коры и рекомендовать парадигму пассивных движений указательным пальцем в заданном темпе для исследования сенсомоторной системы больных с двигательными нарушениями.
