🐠🧠 #Fish use a behavior called the dorsal light response to keep their backs facing the light.
Researchers at #Osaka Metropolitan University found that a specific part of the fish #brain combines information from the #eyes and a light-sensing organ to help them stay balanced while #swimming.

Two organs, one brain area: How fish orient themselves in the water
Using zebrafish, researchers from Osaka Metropolitan University (OMU) have identified the tegmentum region in the fish midbrain as the area where light input from both the fish's eyes and the pineal organ—the "third eye"—is integrated. Their findings, published in the journal Proceedings of the National Academy of Sciences,suggest that fish use the integrated light signals in this region to swim up or down in response to differences in the wavelength of light.
