Topic: optokinetic reflex

To perform advanced behaviors employing vision, mechanisms are necessary to stabilize the scene on the retina, including the optokinetic reflex, mediated by the pretectum (PT). Additionally, this stabilizing responses are modified to redirect our eyes to specific targets playing a key role the optic tectum (OT). Here, we investigated the role of PT and OT in processing optokinetic and non-optokinetic stimuli in the lamprey; an accessible animal model that enables ex-vivo preparations maintaining sensory organs. Moreover, the unique stepwise development of their visual system allows to study th

Investigating vision through naturalistic stimuli holds great promise, because the visual system of any animal species is adapted to its ecological niche. In mice, such adaptations include a field of view exceeding 300° and cone opsins sensitive to UV and green light. These adaptations, however, cannot be probed with standard consumer displays.To present naturalistic stimuli with respect to coverage, color, and content to mice, we built a hemispheric dome setup, enabling the controlled projection of wide-field movies with UV-green spectral content. For our UV-green projection, we used a custom
