abstract: Local neuronal circuits in the neocortex consist of hundreds of neurons [1]. These neurons typically show refractoriness after emitting an action potential (spike), and accumulating refractory effects result in adaptation on multiple time scales [3]. Both finite network size and neuronal adaptation make it difficult to derive population dynamics using traditional, stochastic process approaches. Here we present a novel theory of the population activity of finite-sized, randomly connected networks of spiking neurons with adaptation, which is obtained by approximating neuronal spike emission by a quasi-renewal process [2]. Our theory describes the average firing rate and its spectral density in coupled networks, exemplified for the typical case of a network of excitatory and inhibitory neurons. Furthermore, we show how correlated noise influences the stationary population activity, and how it can contribute to synchronize or desynchronize neuronal circuits. References [1] S. Lefort, C.
