The Neural Basis of Song Recognition in Crickets
Quick fact
A female cricket can recognize the species-specific song of a male with fewer than 50 neurons, using a tiny group of auditory neurons in her brain—a strikingly compact circuit for such a complex recognition task.
Why this is interesting
You're outside on a summer evening, and the air is filled with the rhythmic chirping of crickets. But to a female cricket, that chorus isn't just noise—it's a rich source of information that she must decode with a tiny brain, no bigger than a sesame seed.
