How locust brain senses polarization patterns in the sky

Receptive Fields of Locust Brain Neurons Are Matched to Polarization Patterns of the Sky

Highlights

•
Locust brain neurons integrate polarization signals from all parts of the sky
•
Neural responses to polarized light reflect the E vector pattern in the sky
•
Neurons in the brain act as matched filters to the sky polarization pattern
•
Locusts can determine the solar azimuth by relying on polarization vision alone
