Contrasting with neural network theories, a study of the cross-species perception of dynamic faces with highly realistic human and monkey avatars reveals independent perceptual encoding of facial shape and expression.

Two hour deprivation of vision in one eye transiently boosts the representation of the deprived eye (suppressing the non-deprived eye) in adult human V1 and along the ventral pathway.
The perception of ambiguous steps in relative tone height is predicted by direction-selective cells in the auditory cortex, rather than the brain's represented distance between the tone heights.

Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

A quantitative forward model captures fMRI responses to chromatic stimuli in human primary visual cortex and quantifies how chromatic sensitivity changes with eccentricity.
Oxytocin, but not the structurally similar vasopressin, modulates both the chemosensory decoding of femininity in straight men and that of masculinity in gay men in an inverted-U-shaped manner.
A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.
Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.

A computational model of the initial visual encoding together with Bayesian image reconstruction quantifies how that encoding, combined with the statistical regularities of natural images, shapes key aspects of visual perception.
