Research from Greg Jefferis’s group in the LMB’s Neurobiology Division has uncovered a biological switch that determines which part of the fruit fly’s brain responds to pheromones, depending on whether the fruit fly is male or female. Previous studies have identified differences in brain structure between the sexes but this study, published in Cell, is the first description in any animal of a specific change in nerve cell wiring that reroutes information between male and female brains.
