Psychometric measures reveal that, contrary to common assumption, rats have good visual form discrimination capacity under red and even far-red illumination.

Softer sound appears closer to midline than louder sound, conflicting with a labelled-line representation of auditory space and supporting the idea that humans use rate coding when calculating sound directionality.

Perception in autism is sensitive to absolute rather than to relative metrics of the environment, encoding changes in the environment without calibrating the changes relative to reference stimulation.

Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.

Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

Perceptual decision making, even in simple scenarios, is affected by sensory and decisional choice biases.

Low-frequency correlations among neurons in monkey visual area V4 impair the animal's ability to perform an attention-demanding task, suggesting a causal role of these fluctuations in perception.

When choosing between stimuli, the effort required to act on the resulting decision influences the processing of the stimuli themselves.

Perceptual decisions are influenced by preceding choices to a larger extent in individuals with autism spectrum disorder, such that they demonstrate a greater consistency bias.

In humans, the surface area of early visual cortex across polar angle is distributed in a pattern that correlates strongly with radial asymmetries in behavioral performance on visual tasks.
