User:Diberri/Luria test

In neurology, the Luria test (also called the fist-edge-palm test or FEP) is a test of executive function. In this test, the examiner instructs a subject to sequentially place one of the subject's hands in three different positions called fist, edge, and palm. Difficulty performing this task is often suggestive of frontal lobe dysfunction, although interpretation of subjects' performance is controversial.

A 2002 functional MRI study demonstrated that successful performance of this task required left and right premotor areas, opposite parietal area, same-sided cerebellum, opposite-sided sensorimotor area, and opposite-sided supplementary motor areas.
