Definition

Finger localization refers to the ability to discriminate and name one’s fingers upon tactile stimulation (Andres et al. 2014; Gerstmann 1940). Assessment of finger localization may include the patient identifying the finger stimulated by naming, pointing, recognizing the finger on a picture or drawing, or labeling the finger by number.

The inability to complete this task is called finger agnosia, a type of tactile agnosia. Patients with finger agnosia may present with difficulty naming fingers on command, identifying which finger was touched, and difficulty mimicking specific finger movements. Finger agnosia is often associated as a symptom of Gerstmann syndrome (Gerstmann 1940; Miller and Hynd 2004) which arises from dominant parietal lesions and also typically includes acalculia, left-right confusion, and agraphia (Blumenfeld 2002). Lesions of the left angular gyrus (Penner-Wilger and Anderson 2013), the bilateral posterior...
