Abstract

Vertebrates and insects see eye-to-eye Towards the end of the nineteenth century, Ramón y Cajal, the founding father of neuroscience, observed similarities between the vertebrate retina and the insect eye. His conclusions were based purely on anatomy. Now, using state-of-the-art genetics and electrophysiology, Alexander Borst and colleagues confirm the similarity between vertebrate and insect retinal circuitry, this time at the functional level. They have distinguished motion-sensitive neurons responding to abrupt increases in light (ON-neurons), from those specific for light decrements (OFF-neurons), in the fruitfly Drosophila. Clearly, the selection pressure for efficient motion detection through variations in light intensity has generated similar circuitries in these evolutionarily distant species.
