Multiple Brain Activation Patterns for the Same Perceptual Decision-Making Task

Oct 8, 2024 | biorxiv.org | Johan Nakuci |Jiown Yeon |Nadia Haddara |Ji-Hyun Kim |Ji-hyun Kim

AbstractMeaningful variation in internal states that impacts cognition and behavior remains challenging to discover and characterize. Here we leveraged trial-to-trial fluctuations in the brain-wide signal recorded using functional MRI to test if distinct sets of brain regions are activated on different trials when accomplishing the same task. Across three different perceptual decision-making experiments, we estimated the brain activations for each trial.
