Беременность изменяет мозг женщины на два года – ученые

С течением беременности уменьшается объем серого вещества будущей матери.

 

Магнитно-резонансная томография показала, как с течением беременности уменьшается объем серого вещества будущей матери. Возможно, таким образом организм готовится удовлетворять потребности ребенка. Результаты исследования были опубликованы в журнале Nature Neuroscience.

 

Исследование продолжалось более пяти лет. В нем приняли участие 25 впервые забеременевших и 20 ни разу не беременевших женщин, а также их партнеры. 

 

Результаты сканирования мозга показали четкое различие между будущими матерями и остальными участниками исследования: у первых наблюдалось сокращение серого вещества в медиальной фронтальной и задней теменной коре, а также в префронтальной и височной. Эти области мозга отвечают за чувство эмпатии, способность к пониманию других и прочие социальные процессы. Изменения сохранялись в течение двух лет после беременности.

 

«Эти изменения могут отражать, по крайней мере частично, механизм синаптического прунинга, когда слабые синапсы устраняются, формируя более эффективные и специализированные нейронные сети», – отметил психолог Эльзелин Хокзема из Барселонского автономного университета в Испании. 

Потеря объема серого вещества не связана с негативными последствиями – ни у одной из беременных участниц не было проблем с памятью и другими когнитивными функциями.

Родился первый ребенок от трех родителей

Напомним, ранее ученые назвали токсикоз признаком здоровой беременности.
