Insular Cortex (w. pics)

  1. 1. The Insular Cortex<br />By Hagar & Mikaela<br />
  2. 2. Location<br />Cerebral Hemisphere<br />Connected with the primary/secondar somatosensory areas amygdale , prefrontal cortec, etc.<br />http://upload.wikimedia.org/wikipedia/commons/6/60/Gray743_insular_cortex.png<br />
  3. 3. Functions<br />Bodily Awareness<br />Risky Decision Making<br />Taste-Processing Gustatory Process<br />
  4. 4. Disfuntional Insular Cortex <br />Hard time evaluating pain, and processing it.<br />Plays a positive role in addiction.<br />
  5. 5. Study 1: Sacktor, Weizmann Institute of Science (Rehovot, Israel)<br />Aim: To determine result of blocking an enzyme that strengthens the neuron connections, creating long-term memory.<br />Result: Memories erased by injecting the inhibitor into the insular cortex (taste-processing gustatory process).<br />http://www.ethikpartei.ch/neuron2.jpg<br />
  6. 6. Study 2: Dr. Urbanik <br />Aim: To examine whether men and women respond differently to danger.<br />Results: Men’s insular cortex is more activated than women’s, which creates a physical reaction of ‘fight or flight’ rather than an emotional.<br />http://www.paniccure.com/images/Fight-or-Flight-72.jpg<br />http://www.adoptionblogs.com/media/OpenAdoption/girl-scared-and-wet.jpg<br />
  7. 7. Study 3: Nasir Naqvi, University of Iowa<br />Aim: To see whether head injury that leads to dysfunction of the Insular Cortex will have an effect on drug addiction. <br />Results: Cigarette smokers for example who suffer from damage of the Insular Cortex due to a stroke had their addiction to cigarettes almost eliminated. Up to 136 more likely to stop smoking then smokers who suffer damage to another part of the brain.<br />Make this area of the brain a promising target for anti-addiction medications. <br />
