Stimulating PV cells at nonsilencing levels during entire stimulus presentation or late phase V1 activity impairs discrimination performance, whereas stimulating during early phase V1 activity improves performance.

Stimulating PV cells at nonsilencing levels does not improve performance of difficult visual discriminations.
Dahkki: Lilia Kukovska (22683586)
Almmustuhtton: (2025) -
PV cell activation alone does not induce changes in behavioral redouts during the stimulation period (0–2 s).

Changes in neural selectivity caused by PV cell activation reflect behavioral performance in easy but not difficult discriminations.
