PPC neurons modulate their activity based on evidence strength, influencing decision outcomes.
Transitional responses to evidence were noted, with effects tapering off over time, reflecting behavioral evaluation.
Recording spiking activity using Neuropixel probes revealed distinct modulation of neuronal groups in decision-making tasks.
Inactivation of PPC significantly altered choice behavior and the timescale for evaluating sensory evidence.
