Human hippocampus stained with a method pioneered by Italian physician Camillo Gogli in 1873.
Golgi discovered a chemical reaction that allowed him to examine nervous tissue in much greater detail than ever before. For some reason, hardening a piece of brain in potassium dichromate, and subsequently dousing it with silver nitrate, dyed only a few cell bodies and their respective projections in the tissue sample, revealing their complete structures and exact arrangement within the unstained tissue. If the reaction had stained all the neurons in a sample, Golgi would have been left with an unfathomable black blotch, as though someone had spilled a bottle of ink. Instead, his technique yielded neat black silhouettes against a translucent yellow background.

Участки мозга, возбуждающиеся у любящих людей в ответ на стимулы, связанные с объектом любви (комбинированная схема, составленная по результатам шести исследований). Чем светлее оттенок красного, тем в большем числе разных опытов, ориентированных на разные аспекты и разновидности любви, отмечалось повышенное возбуждение данного участка мозга. Верхние изображения — наружная поверхность полушарий, нижние — медиальная поверхность («продольный срез» мозга). Изображение из обсуждаемой статьи в The Journal of Sexual Medicine

Scarless brain surgery is new option for patients -

Surgeons at the University of California, San Diego, School of Medicine and University of Washington Medical Center have determined that transorbital neuroendoscopic surgery (TONES) is a safe and effective option for treating a variety of advanced brain diseases and traumatic injuries. This groundbreaking minimally invasive surgery is performed through the eye socket, thus eliminating the removal of the top of the skull to access the brain. These findings were published in the September issue of Neurosurgery.
