The gated cascade diffusion model: An integrated theory of decision making, motor preparation, and motor execution.

Edouard Dendauw,
Nathan J. Evans,
Gordon D. Logan
et al.

Abstract: This article introduces an integrated and biologically inspired theory of decision making, motor preparation, and motor execution. The theory is formalized as an extension of the diffusion model, in which diffusive accumulated evidence from the decision-making process is continuously conveyed to motor areas of the brain that prepare the response, where it is smoothed by a mechanism that approximates a Kalman-Bucy filter. The resulting motor preparation variable is gated prior to reaching agonist muscles until … Show more

“…Regions such as the dorsolateral prefrontal cortex (dlPFC), dorsomedial prefrontal cortex (dmPFC), premotor cortex(PMC), and supplementary motor area(SMA) are key brain regions for motor control. The coordination of these brain regions ensures the smooth flow of motor processes ( 45 ). The neural circuits involved in cognition, especially motivation, are mainly concentrated in the PFC, sharing common key brain regions with motor control.…”

“…Their popularity and success has led to the proposal of numerous modifications to the original DDM concept. Such proposals have modified the drift rate (Cisek, Puskas, & El-Murr, 2009;Dendauw et al, 2024;Ditterich, 2006;Smith, 1995;? ), the diffusion rate (Cisek et al, 2009;Trueblood, Heathcote, Evans, & Holmes, 2021), and the shape of the decision thresholds (Churchland, Kiani, & Shadlen, 2008;Ditterich, 2006;Evans & Hawkins, 2019;Evans, Hawkins, & Brown, 2020;Hanks, Mazurek, Kiani, Hopp, & Shadlen, 2011;Hawkins, Forstmann, Wagenmakers, Ratcliff, & Brown, 2015;Palestro, Weichart, Sederberg, & Turner, 2018; ?…”
