Transitions in dynamical regime and neural mode underlie perceptual decision-making

TZ Luo, TD Kim, D Gupta, AG Bondy, CD Kopec… - bioRxiv, 2023 - biorxiv.org
Perceptual decision-making is the process by which an animal uses sensory stimuli to
choose an action or mental proposition. This process is thought to be mediated by neurons …

Temporal order judgment of multisensory stimuli in rat and human

F Mafi, MF Tang, MR Afarinesh… - Frontiers in Behavioral …, 2023 - frontiersin.org
