What resolves this contention: {'position': 'PV maturation is the primary trigger for critical period plasticity', 'evidence_description': 'GAD65 knockout mice lack critical period; accelerating PV maturation with BDNF or benzodiazepines accelerates critical period onset'} / {'position': 'Multiple interneuron types contribute to critical period timing through overlapping mechanisms', 'evidence_description': 'SST interneurons mature before PV and establish early inhibitory circuits; VIP disinhibitory circuits also modulate plasticity windows; layer-specific critical periods have different timing'}
