Overview

EEG analysis reveals neural signatures of sensory variance and its impact on metacognitive sensitivity in decision-making.

Key Points

  • Core finding shows that neural responses correlate with sensory evidence variance, affecting decision confidence.
  • EEG signals identified frontal and centro-parietal regions tracking variability, with strongest responses at intermediate uncertainty.
  • Participants judged grating orientations, linking neural activity in alpha and stimulus-entrained bands to perceptual variance.
  • Understanding these neural and behavioural correlates enhances insights into the brain's encoding of uncertainty.
