Anticipated distractor processing relies on distinct representational states before and after distractor onset in visual working memory

This study uses EEG and multivariate decoding to show that anticipatory coding of distractors in visual working memory does not protect behavior, but post-distractor reformatting reduces interference.

Orthogonal representational geometry in dACC underpins human hierarchical reasoning

The paper shows that orthogonal representational geometry in dACC supports hierarchical reasoning by encoding error and difficulty along separate dimensions.

Representational dynamics during extinction of fear memories in the human brain

This study uses iEEG and RSA to show that human extinction learning involves context-specific neural representations in the amygdala and extinction network, with theta oscillations signaling safety and predicting fear or safety responses.

Earlier finish of motor planning in the premotor cortex predicts faster motor command in the primary motor cortex: human intracranial EEG evidence

The paper uses intracranial EEG to show that earlier motor planning in premotor cortex predicts faster motor execution in primary motor cortex, correlating with shorter reaction times.

Cross regional coordination of neural activity in the human brain during autobiographical self-referential processing

The paper investigates fast neural coordination across brain regions during autobiographical memory processing using intracranial recordings in humans.

Auditory stimuli extend the temporal window of visual integration by modulating alpha-band oscillations

The paper shows that auditory stimuli prolong the visual integration window by altering alpha-band oscillations, as evidenced by changes in psychometric thresholds and neural activity patterns.

Crossmodal reorganization in deaf auditory cortices compensates for the impaired body-centered visuomotor transformation after early deafness

This study shows that early deafness leads to cross-modal reorganization in auditory cortices, which functionally couples with frontoparietal and default-mode networks, affecting visuomotor transformation performance.

Electrophysiological signatures of hierarchical learning

The paper investigates hierarchical learning by combining a hierarchical Bayesian model with EEG data during a probabilistic reversal learning task, showing distinct neural encoding of low- and high-level prediction errors.

Perceptual inference employs intrinsic alpha frequency to resolve perceptual ambiguity

The paper shows that alpha-band frequency helps the brain resolve perceptual ambiguity by integrating sensory information and biasing perception towards predicted outcomes.
