Fly Brain Diagram (IMAGE)
Caption
Princeton University researchers used fruit fly brains to capture the process by which the brain identifies behaviorally useful information in the external environment and uses it to determine our actions. They attached small electrodes to individual neurons in the auditory pathway of a female fly's brain to record electrical activity as she heard male mating songs, which the male generates by vibrating his wings. A diagram of the fruit fly brain (above) highlights the structure of all seven of the brain neurons included in the study, with different colors corresponding to different neurons. Despite the great diversity in neuron structure, all neurons had very similar responses to male fly songs.
