Алкоголь не помогает избавиться от неприятных воспоминаний

По оценкам специалистов, от 60 до 80 процентов людей используют алкоголь в качестве «лекарства» от негативных воспоминаний

При употреблении алкоголя негативные воспоминания становятся ярче, заявили специалисты Университета Джона Хопкинса. Ученые выяснили, что алкоголь укрепляет связь между нейронами и мозговым центром страха, пишет Dailymail.

Для подтверждение этой теории ученым пришлось провести опыт над мышами. Используя эликтрический разряд грызунам вырабатали страх, когда те слышали определенный звук. После чего мышей разделили на две группы. Первая группа принимала обычную воду, а вторая с содержанием 20% этанола. На следующий день исследователи повторяли воспроизведенные звуки, чтобы проверить, как будут реагировать на них грызуны.

Выяснилось, что те грызуны, которые принимали алкоголь, замирали в ожидании удара тока, чем те, кто пил обычную воду. Все дело в том, что в синапсах (соединениях между нейронами) у экземпляров, получавших алкоголь, содержится больше рецепторов. Из-за того, что эти соединения были крепче, негативные воспоминания о прошлом дне было устранить тяжелее, мыши находились в напуганом состоянии. Затем мышам, принимающим алкоголь, дали лекарственный препарат, который блокирует рецепторы, что позволило снизить снизить реакцию на звуки на 20%.
