Dynamic Neural Deactivation Bridges Direct and Competitive Inhibition Processes.

ABSTRACT: Inhibition is an important concept in cognitive neuroscience. Direct inhibition, characterized by the active suppression of stimuli, and competition-induced inhibition, which involves ignoring irrelevant stimuli by prioritizing relevant ones, have traditionally been considered distinct and studied separately. Although their spatial neural overlap has been highlighted, the temporal dimension-the development of neural activities over time-remains largely unexplored. Using multimodal neuroimaging and behavioral experiments in the auditory and visual domains, in addition to conjunction analyses that capture their neural commonalities, we observed that both inhibition types exhibit a shared deactivation temporal dynamic. It is characterized by a progressive reduction in frontoparietal activatio
