PV plasticity sustained through D1/5 dopamine signaling required for long-term memory consolidation

This study shows that learning-induced plasticity of local parvalbumin (PV) basket cells is specifically required for long-term, but not short to intermediate-term, memory consolidation in mice. PV plasticity depends on local D1/5 dopamine receptor signaling 12–14 h after acquisition for its continuance, ensuring enhanced sharp-wave ripple densities and memory consolidation.
