The Greek physician <u>Herophilus </u>noted that separate spinal nerves connect to each region of the body.

His work is recorded in his books <em>On Pulses</em> and <em>Midwifery</em>. Galen also quoted him extensively.

He also studied the human brain, which he believed is the locus of the intellect, and differentiated between the cerebrum and cerebellum.
