Autistic Traits are Associated with Suboptimal Decision Bias Strategies in Subsecond Timing

This study finds that autistic traits are linked to a suboptimal decision bias strategy in subsecond timing tasks, not reduced perceptual sensitivity.

Targeted Neuromodulation of Perceptual Decision-Making Networks Causally Dissociates Sensory and Metacognitive performance

This study uses targeted neuromodulation to show that sensory and metacognitive performance in motion perception are dissociable, with V5/MT+ affecting discrimination and IPS/LIP affecting confidence.

The aging rhythm: spatio-temporal dynamics of resting alpha oscillations in young and older brains

This study examines age-related changes in alpha oscillations using EEG data, finding slowed peak frequency, reduced power, and altered spatiotemporal propagation in older adults.

The confidence code: parietal alpha oscillations turn expectations into beliefs

The paper shows that parietal alpha oscillations mediate metacognitive bias by linking expectations to confidence judgments.

Reduced Backward Alpha Propagation at Rest Marks the Autism Continuum

The paper examines resting-state EEG data from individuals with varying autistic traits, finding a directional shift in alpha-band traveling waves in the left hemisphere associated with higher autistic traits.

Aging redirects prior expectations from perception to action

This study shows aging changes how the brain uses prior expectations in decision-making, leading to stronger bias and reduced sensory precision, with neural changes in alpha and beta rhythms.

Strengthening interhemispheric connectivity increases interregional information transfer between human primary motor areas

The paper shows that strengthening connections between left and right motor cortex increases information transfer in specific EEG frequency bands in right-handed individuals.

Predictive inference alterations in psychosis proneness are context-dependent

The paper investigates how psychosis-like traits affect perceptual inference in different tasks, finding context-dependent alterations in how prior expectations interact with sensory input.

Preparing to act follows Bayesian inference rules

This study shows that prior expectations shape motor excitability before action execution, with individual differences linked to autistic and schizotypal traits.

Backward alpha oscillations shape perceptual bias under probabilistic cues

This study shows that alpha-band traveling waves mediate prior-driven perceptual bias by propagating from frontal to occipital areas during decision-making.
