End of Semester Brain Asymmetries

Illustration of a group of Flamingos; these birds turn their neck to the left or right when resting and the direction of this predicts their level of aggression.The tide of new books continues to roll in, just as students are less likely to want anything else to add to the mix of completing projects, studying for finals and returning library materials.  Nevertheless, there are many delightful books that offer a respite - just 15 minutes of reading a portion of Divided Brains (for example) could give you renewed enthusiasm for whatever lies ahead.  Development of lateralization in the brain is evidenced by a wide array of behavior and skills, from tail wagging in dogs (the tail swings farther to the one side or the other, depending on whether the dog is being approached by its owner or by a more dominant dog) to a larger than average posterior area of the right hippocampus in London taxi drivers (the size of the hippocampus relates directly to spatial ability).  Don't ask how we know - come take a quick look at the book and see what else is of interest on the new books shelf.
