Speed Inversion in a Potts Glass Model of Cortical Dynamics
Kwang Il Ryom, Alessandro Treves
Abstract
The authors of this study model the cortex as a network of Potts units. They observe a phenomenon, known as ``speed inversion'' where the ``frontal'' units, initially slower in isolation, become faster than the ``posterior'' units when interacting, which may play a role during learning.
