The remarkable navigation abilities of the rock pigeon (Columba livia) are facilitated by a sensory system that allows the detection of magnetic fields. While there is compelling behavioral evidence demonstrating the existence of a magnetic sense, the neuronal circuits that process magnetic information in the brain are largely unknown, and the primary sensory cells and transduction molecules have yet to be identified. To address these issues, we combined tissue clearing and light sheet microscopy to screen the pigeon brain for magnetically induced neuronal activity via C-FOS expression. This s
