Antonio Pacchioni

Antonio Pacchioni (1665–1726) was an Italian scientist and anatomist, who focused chiefly on the outermost meningeal layer of the brain, the dura mater.

Pacchioni's granulations (or pacchionian bodies), where the arachnoid layer protrudes through the dura, are named for him (although they are now generally known as arachnoid granulations).

Pacchioni was born in Reggio Emilia, where he later attended university. He received his degree in medicine in 1688, and left for Rome in 1689.
