Cortical activity is characterized by oscillatory dynamics at many scales. To capture such dynamics in a computational model and elucidate on its putative functional roles, we simulated recurrent networks consisting of coupled damped harmonic oscillators (DHOs), so called HORNs. In HORNs, each DHO node represents the aggregate activity of a recurrently connected E-I circuit such as a cortical column. Mathematically, a DHO is given by a 2nd order ordinary differential equation with a single state variable x (amplitude) To model different intrinsic properties of an underlying E-I circuit's recur
