A recent paper published in Nature suggests that we have been using the wrong scale to compare mammalian brains - instead of a ratio of brain-size to body-size for each mammal, we should compare ratios of normalized brain component sizes. Meanwhile, Newsweek is running a cover story about research into a variety of neurological underpinnings to mystical and religious experiences in the human brain. And finally, Ken Catania of Vanderbilt University has been studying some rather odd mammals such as star-nosed moles that have only one major sensory organ and a very large portion of their brain devoted to processing input from it. Understanding how they manage with primarily one sense might have direct applications to robotics.
