Chemogenetics

Chronic downregulation of parvalbumin-positive cell activity accelerates early perceptual learning but impairs end performance

These findings suggest that PV+ cells regulate perceptual learning, "for better and for worse".

Reactivation of critical period plasticity in adult auditory cortex through chemogenetic silencing of parvalbumin-positive interneurons
