Have you heard of PALATAL MYOCLONUS (tremor), a very rare condition affecting muscles of the soft palate. It presents with a persistent CLICKING NOISE. Where is the lesion? #neuroscience #neurotwitter #Medical
Precise #localization: It occurs due to infarction, bleed or tumor within the Guillain-Mollaret Triangle in the brainstem. The triangle includes the midbrain red nucleus, medulla inferior olivary nucleus, and contralateral cerebellum dentate nucleus. 
Often patients report tinnitus and merely asking patients to open their mouth demonstrates the characteristic clicking noise. The patients sense the sound in their ears.
