NySTAGmus

A couple of things to remember about ny-STAG-mus:

• Can be caused by lesion to flocculonodular lobe (shaped like bow-tie) of cerebellum
  
• Gaze is controlled by vestibulo-cerebellum
  
• Vascular supply: Anterior Inferior Cerebellar Artery (AICA)

Explaination of image: This STAG is wearing a VEST with a BOW TIE. He's also talking to us asking if we like his bow-tie - so he must have some artificial intelligence (A.I. = AICA).

ps. for brownie points the deep nucleus of the vetibulo-cerebellum is the lateral vestibular or Deiter's nucleus. You could remember this by naming your stag "Deiter"...
