This paper shows that perceptual axioms, as experienced in optical illusions, cannot align with Euclidean geometry, indicating a fundamental disconnect between perceptual and mathematical logic.

This study investigates the neural basis of conscious visual awareness in Riddoch syndrome using multimodal MRI, finding that V5 activity correlates with conscious perception of motion in blind fields.

This study investigates neural correlates of abstract beauty by analyzing brain activity during aesthetic ratings of abstract paintings, finding similar patterns to facial beauty in visual and medial frontal cortex activity.

The paper investigates the neural basis of facial beauty by analyzing brain activity patterns during aesthetic experiences using fMRI.

The paper discusses the distinction between two types of priors in Bayesian inference, arguing that biological priors are more universal and resistant to change than artifactual ones.

The paper tests color category perception across diverse subjects using Land Colour Mondrian experiments, finding consistent categorization of warm hues but variability in cool hues.

The paper investigates whether mathematical beauty is biologically or culturally determined, finding that it exhibits less variability in aesthetic ratings, aligning with biological beauty.

The paper measures early cortical responses to color stimuli using MEG and finds an early response at 30 ms in prestriate cortex, aligning color with motion and form systems.

This study shows that the color of after-images depends on surrounding light, not just the light from the viewed patch, challenging traditional explanations of after-images.
