"The Beautiful Brain" at NYU's Grey Art Gallery features the drawings of the Spanish artist and scientist Santiago Ramón y Cajal (1852–1934).  Known as the father modern neuroscience, Cajal is credited with discovering intricate functions of the brain long before the benefits of modern medical imaging. 

His astonishing and detailed drawings portraying the infinite complexity of the human brain are still used in textbooks today. Nearly 80 of Cajal's images are on display alongside contemporary brain scans at the Grey Gallery through March 31, 2018.
