Visual Neurons Mapped In Action

Have you ever tried to swat a fly? They are very good at sensing motion and evading the flyswatter. New studies show how flies see movement.

Scientists have mapped the dense interconnections and neuronal activity of mouse and fruitfly visual networks. The research teams, whose work is published in three separate studies today in Nature1–3, also created three-dimensional (3D) reconstructions, shown in the video above.

These studies looked at tiny bits of neuronal networks in animal retinas but scientists hope to eventually map the full sets of connections of entire brains — including human ones.
