Как отмечает Jackson, в коре больших полушарий человека сосредоточено около четырнадцати миллиардов нейронов. Однако это лишь часть системы: глиальных клеток, которые обслуживают нейроны, в десять раз больше. Такое огромное количество элементов упаковано в тонкий слой ткани толщиной от одного до пяти миллиметров, что создает невероятную плотность биологических событий и вычислительную мощность нашего мозга.
Неокортекс, или новая кора, является эволюционно самой молодой частью мозга, о чем рассказывает Eli. Она составляет семьдесят два процента всей площади коры и почти половину общей массы мозга. Если разгладить все складки и извилины этой «простыни», то общая площадь поверхности коры составит до двух тысяч двухсот квадратных сантиметров, обеспечивая работу высших психических функций.
Кора головного мозга, или cortex cerebri, играет ключевую роль в формировании человеческой личности. По словам Eli, именно эта структура отвечает за способность осознавать себя, планировать будущее и вести дискуссии. Благодаря сложной организации неокортекса мы можем обрабатывать информацию, принимать решения и осуществлять сложную интеллектуальную деятельность, которая отличает нас от других видов.
Цитоархитектоника — это специальная наука, изучающая строгое расположение и выстраивание клеток в мозге. Eli объясняет, что клетки в коре не свалены в кучу, а организованы в четкие слои, напоминая сложный торт. В неокортексе обычно выделяют шесть таких функциональных слоев, каждый из которых имеет свою специфику и отвечает за определенные этапы обработки информации.
