Abstract
The oculo-auricular phenomenon (OAP), as described by Wilson in 1908 [26], consists of bilateral coactivation of external ear muscles during lateral gaze. Two ear muscles are innervated by motoneurons of the medial part of the facial nucleus [9, 25]: the transverse auricular muscle (TAM) (Fig. 1), which adducts and curls the helix of the auricle, and the posterior auricular muscle (Fig. 2), which moves the whole auricle backwards [3, 16, 22].
