bodypart as object gesture
bodypart as object gestureA body part as object (BPO) gesture is an error pattern seen in ideomotor apraxia, in which patients represent objects using their hands—e.g., the wrist is held stiff to represent a hammer; the finger is held rigid and the hand twists to represent a key in a lock. The BPO gesture is similar to ordinary pantomime in normal subjects by functional magnetic resonance imaging (fMRI); both activate the left parietal areas (Brodmann's area (BA) 7, 40), irrespective of the hand used.
