You realize that you may be coming down with something besides allergies. Pick one of the behavioral changes you are experiencing (e.g., increased sleepiness or decreased hunger), identify and explain (i) at least one potential immune mediator that could influence this behavior, (ii) a brain area involved, and (iii) at least one predicted change in a neurochemical involved in the sickness-induced behavioral change.
