Neurology in Tulp's Observationes medicae.

The beginning of the seventeenth century marked the start of a scientific revolution, which had consequences for medicine. Vesalius in anatomy, and Harvey in physiology, were important figures who gave the Hippocratic and Galenic traditions new impulses. In this period of change in medical thought, Nicolaas Tulp (1593-1674) wrote his 'Observationes Medicae' (Tulp, 1641). A controversy existed in The Netherlands, concerning the circulation, with many doctors still adhering to the Galenic tradition. The following analysis discusses some of the neurologic cases from Tulp's book, seen in the light of modern medical thought.
