Topic: damped harmonic oscillators

Biological neuronal networks exhibit hallmark features such as oscillatory dynamics, heterogeneity, modularity, and conduction delays. However, it has remained unclear to what extent these serve computational purposes. Inspired by physiological findings, we simulate recurrent networks of damped harmonic oscillators (DHO) in which one network node represents the aggregate activity of an underlying E-I circuit such as a cortical column (HORNs, see figure), at the same time reducing single-node oscillatory dynamics to its most basic form. We successively endow the networks with additional biologi
