Overview

Intracranial recordings reveal evidence accumulation in the ventral visual cortex influences perception, implying confidence levels matter.

Key Points

  • Evidence accumulation explains subjective visual perception even when reports are absent, emphasizing the neural basis of perception.
  • High-gamma activity correlates with reaction times, showing evidence accumulation's role in visual processing across various stimulus conditions.
  • Observational analysis using stereo-electroencephalography highlighted distinctions in visual stimuli detection and reported confidence levels.
  • Implications may extend to understanding disorders of perception where individuals struggle with report accuracy or confidence.
