He also provided experimental proof for the specificity of the reconnection of regenerating severed neurons in newts, which later led to new theories on how neurons grow. After 1965, his work turned more to psychology and philosophy.

His research in the histology of the blood established hematology as a field. Ehrlich also developed new staining methods for microscopic studies on live tissue. At a time when little was understood about the mechanism of disease caused by bacteria, he proposed the side-chain theory as a chemical explanation of immunity, the body's defenses against infection. Though broadly incorrect, the theory nevertheless stimulated further work on the problem. He shared the 1908 Nobel Prize for Physiology or Medicine with Russian bacteriologist, Élie Metchnikoff.
