Deric Bownds at Mindblog, always a font of interesting and useful neuro information, posted about a meeting he was at where A.D. Craig, who researches pain and the insular cortex which helps to process it into conscious awareness, presented his ideas on the functional difference between the left and right insulas with regard to deep breathing. Check it out. Thumbs up.
My own insula seems to light up irresistibly whenever the word "insula" appears, and is drawn to examining whatever new scrap of info might have turned up. I've written about the insula before, here and here.
Here are some articles about the insula:
