The dynamic relationship between pupil dilation and neural surprise in natural language comprehension

The paper investigates how pupil dilation and neural activity reflect different aspects of predictive processing during language comprehension, finding dissociable responses to lexical surprise and semantic error.

Temporal predictions as motor readouts of sensory predictions

The paper shows that temporal predictions in vision are linked to motor readouts and content-specific encoding in early visual areas during timing judgments.

Eye Movements in Silent Visual Speech track Unheard Acoustic Signals and Relate to Hearing Experience

This study shows that eye movements track unheard speech during silent lip-reading and relates to hearing experience, with differences between hearing and deaf groups.

Ocular Response Functions reveal how ocular processes relate to neural activity

The paper models Ocular Response Functions (ORFs) using MEG and eye tracking to reveal neural signatures of oculomotor events and their relationship with neural activity.

Eye movements track prioritized auditory features in selective attention to natural speech

The paper shows that eye movements track acoustic features of attended speech, differentiating targets from distractors and relating to speech intelligibility.

Prediction tendency, eye movements, and attention in a unified framework of neural speech tracking

The paper investigates the relationship between prediction tendencies, eye movements, and neural speech tracking, proposing a unified framework for understanding speech processing.

Individual prediction tendencies facilitate cortical speech tracking

The paper quantifies individual auditory prediction tendencies and shows they facilitate cortical speech tracking and interact with noise and word surprisal.

Direct cochlear recordings in humans show a theta rhythmic modulation of the auditory nerve by selective attention

This study shows that selective attention modulates theta-range auditory nerve activity in humans, with a classifier decoding attended modality from single-trial data.
