This page covers biological details of component group Insular Cortex. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Cortex -> Temporal Lobe (NC.LOBE.TEMP) -> Insular Cortex (NC.INS) (see Mind Maps)
• Function: Visceral representation, pain, habits
• Notes to function: Interoception, merges tactile and auditory streams

Components

Component items:

• Posterior Insular Cortex: Awareness and sensation of pain
• Anterior Insular Cortex: Risky and moral decision making, articulation
• Anterior Temporal Lobe: Relaying blood pressure and blood chemistry information to brain
• Peripaleocortical Claustral: Relays proprioception
