A new empirical challenge for local theories of consciousness [PDF]
, 2021 Local theories of consciousness state that one is conscious of a feature if it is adequately represented and processed in sensory brain areas, given some background conditions.

Comodulation enhances signal detection via priming of auditory cortical circuits [PDF]
, 2016 Acoustic environments are composed of complex overlapping sounds that the auditory system is required to segregate into discrete perceptual objects. The functions of distinct auditory processing stations in this challenging task are poorly understood ...

Masking of figure-ground texture and single targets by surround inhibition: a computational spiking model. [PDF]
PLoS ONE, 2012 A visual stimulus can be made invisible, i.e. masked, by the presentation of a second stimulus. In the sensory cortex, neural responses to a masked stimulus are suppressed, yet how this suppression comes about is still debated.

JND-Based Perceptual Video Coding for 4:4:4 Screen Content Data in HEVC [PDF]
, 2018 The JCT-VC standardized Screen Content Coding (SCC) extension in the HEVC HM RExt + SCM reference codec offers an impressive coding efficiency performance when compared with HM RExt alone; however, it is not significantly perceptually optimized.

Auditory temporal resolution and backward masking in musicians with absolute pitch
Frontiers in Neuroscience, 2023 Among the many questions regarding the ability to effortlessly name musical notes without a reference, also known as absolute pitch, the neural processes by which this phenomenon operates are still a matter of debate.

Visually Lossless Perceptual Image Coding Based on Natural- Scene Masking Models [PDF]
, 2016 Perceptual coding is a subdiscipline of image and video coding that uses models of human visual perception to achieve improved compression efficiency. Nearly, all image and video coders have included some perceptual coding strategies, most notably visual

Neural correlates of auditory perceptual awareness under informational masking. [PDF]
PLoS Biology, 2008 Our ability to detect target sounds in complex acoustic backgrounds is often limited not by the ear's resolution, but by the brain's information-processing capacity. The neural mechanisms and loci of this "informational masking" are unknown.

A Unified Theory of Psychophysical Laws in Auditory Intensity Perception
Frontiers in Psychology, 2020 Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens’s power function as the psychophysical law, few believe in Fechner’s original idea using just-noticeable-differences (jnd) as a ...
