Abstract

Psychiatrist Adolf Meyer’s work as a neuroanatomist is less well-known among the medical community. Using manuscripts by Harvey Cushing and by Meyer himself, Schijns and Koehler explore how Meyer’s anatomical studies enabled him to describe the temporal loop of the optic radiation, known today as ‘Meyer’s loop’.
