Natural scenes consist of complex feature distributions that shape neural responses and perception. However, in contrast to single features like stimulus orientations, the impact of broadband feature distributions remains unclear. We, therefore, presented visual stimuli with parametrically-controlled bandwidths of orientations and spatial frequenci...

Preterm birth is detrimental to the well-being of both the mother and the newborn. During normal gestation, the myometrium is maintained in a quiescent state by progesterone. As a steroid hormone, progesterone is thought to modify uterine and placental morphology by altering gene expression, but another direct mode of action has long been suspected...

Natural scenes are composed of complex distributions of visual features that drive neural response patterns and shape visual perception. However, most stimuli that are commonly used in vision research only reveal neural responses to single features, such as a specific stimulus orientation. How larger feature distributions affect neural responses an...

Natural scenes are composed of a wide range of edge angles and spatial frequencies, with a strong overrepresentation of vertical and horizontal edges. Correspondingly, many mammalian species are much better at discriminating these cardinal orientations compared to obliques. A potential reason for this increased performance could be an increased num...

The visual system of the mouse is a long-standing component of neuroscientific research. There is an ongoing discussion about how to stimulate the visual system in a meaningful way. Here, stimulation competes with artificial and nature-inspired stimuli. The main difference is the different degree of parameterization of the two stimulus approaches....

Warning colouration reduces predation risk by signalling or mimicking the unpleasantness of prey and therefore increases survival. We tested in two experiments the evolutionary costs and benefits of the yellow colour pattern in fire salamanders (Salamandra salamandra), which display a yellow/black colour pattern usually associated with toxic alkalo...
