Google и Гарвард создали 3D-модель части человеческого мозга

Инженеры из Гарвардского университета совместно с Google смоделировали [https://blog.research.google/2021/06/a-browsable-petascale-reconstruction-of.html?m=1] подробную трехмерную карту височного отдела человеческого мозга. Она описывает 1 кубический миллиметр, то есть одну миллионную часть всей коры мозга. При создании модели ученые исследовали ткань мозга пациентки, больной эпилепсией. Фрагмент разрезали на тысячи примерно равных частей, затем сканировали с помощью электронного микроскопа. Получившиеся 255 миллионов двумерных изображений соединили в общую 3D-модель.

Созданная карта содержит 50 тысяч и 130 миллионов синапсов и более мелкие части клеток — например, аксоны и дендриты. Собранные данные занимают 1,4 петабайта. Это в 700 раз больше, чем может хранить обычный компьютер.
