The term middle short gyrus refers to the least developed of three short insular gyri identified by dissection in the anterior insula of the human. The short insular sulcus separates it from the anterior short gyrus rostrally and the precentral insular sulcus separates it from the posterior short gyrus caudally ( Ture-1999 ). The insular gyri do not exist as topological fieatures in macaques or rodents ( NeuroNames ).
