Comparable phosphene size and contrast properties, but differing detection reliability for optogenetic versus electrical stimulation of macaque V1

Kumari Liza, Marta Falkowska-Kisiel, Jaime Cadena-Valencia…·Michael C. Schmid

This study compares perceptual properties of phosphenes evoked by optogenetic and electrical stimulation in macaques, finding comparable size and contrast but lower detection reliability for optogenetic methods.
