Tucked deep within the human brain's lateral fissure, beneath layers of the cerebral cortex, lies the insula. It is the hub that controls sensations ranging from pain and physical touch to hunger and emotions. Yet, it remains an enigma that neuroscientists have been trying to crack for ages. A recent study published in Nature has presented a new, detailed picture of certain regions of the insula that not only provides a new perspective but also questions some older ones.
