Mistichelli's crossing

Related people

Pyramidal decussation.

Description

Pyramidal decussation. In 1709 Mistichelli produced the first diagram of the crossing of the pyramidal tracts. A year later François Pourfour du Petit (1664-1741) reported that unilateral hemiplegias in humans resulted from damage to the contralateral cerebral hemisphere.

We thank Andreas Schoeck for calling our attention to this eponym.
