Как размер мозга влияет на продолжительность зевка?
LIFE
Чем больше размер мозга, тем дольше человеку или животному нужно зевать для охлаждения мозга. Об этом сообщается в исследовании, опубликованном в журнале Communications Biology.
Как сообщает РИА Новости, ученые провели эксперимент с участием 55 млекопитающих и 46 птиц. Они исследовали 1291 зевок и обнаружили устойчивую связь между продолжительностью зевка и числом нейронов мозга.
Исследование показало, что больший по размеру мозг имеет более высокие потребности в термолизе (выводе тепла из организма), тогда как его температура частично определяется выделением тепла вследствие активности нейронов. Более того, млекопитающие зевают дольше, чем птицы, из-за более высокой температуры тела.
