Beyond Neural Noise: Critical Dynamics Predict Slower Reaction Times in Adults With and Without ADHD

Alessandra Dallavecchia, Nicholas Zink, Samantha Reina O’Connell, Samantha Betts, Sean Noah, Austin Hilberg, Mercedes T. Oliva, James T. McCracken, Rory C. Reid, Gregory V. Simpson, Sarah L. Karalunas, Vince D. Calhoun, Agatha Lenartowicz
