limen insula
Acronym: lmi
The term limen insula refers to the rostral surface of the junction between the insula and the temporal lobe in the human ( Ture-1999 ) and the macaque ( Mesulam-1982 ). More specifically, in the human it is the rostral surface of the junction of the anterior long gyrus of the insula with the piriform area of the parahippocampal gyrus. Identified by dissection, its medial border on the ventral surface of the brain is with the olfactory tubercle, which in primates is commonly referred to as the anterior perforated substance ( Duvernoy-1992 ). The limen insula has no topological equivalent in rodents.
