A brief time window of visually evoked activity in mouse primary visual cortex is sufficient for perceptual discrimination.

Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

Enhanced perceptual discrimination occurs when ongoing population activity in visual cortex is in a 'silent' mode in which neurons optimize information extraction.

Training-induced perceptual gain in the discrimination between odor enantiomers is nostril-specific and structure-based, indicating that early olfactory processing of the chemical features of unirhinal input remains plastic in human adults.

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

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.

Combining GABA with fMRI measurements in the human brain uncovers distinct suppression mechanisms that optimize perceptual decisions through learning and experience-dependent plasticity in the visual cortex.

A recent claim that humans can discriminate 1 trillion odors is found to be unwarranted, and further analysis offers insights into the dimensionality of olfactory perception.

Bilateral removal of cortical area 'TE' produced deficits in monkeys' ability to discriminate among images with many similar features, whereas removal of subjacent rhinal cortex did not.

Pharmacological fMRI reveals that associative connections contribute to odor categorization by supporting discrimination and generalization at different stages of the human olfactory system.
