21 p, 2.3 MB Firing rate equations require a spike synchrony mechanism to correctly describe fast oscillations in inhibitory networks / Devalle, Federico (Universitat Pompeu Fabra. Departament de Tecnologies de la Informació i les Comunicacions) ; Roxin, Alex (Centre de Recerca Matemàtica) ; Montbrió, Ernest (Universitat Pompeu Fabra. Departament de Tecnologies de la Informació i les Comunicacions)
Recurrently coupled networks of inhibitory neurons robustly generate oscillations in the gamma band. Nonetheless, the corresponding Wilson-Cowan type firing rate equation for such an inhibitory population does not generate such oscillations without an explicit time delay. [...]

24 p, 7.9 MB Network mechanisms underlying the role of oscillations in cognitive tasks / Schmidt, Helmut (Centre de Recerca Matemàtica) ; Avitabile, Daniele (Inria Sophia Antipolis Méditerranée Research Centre) ; Montbrió, Ernest (Universitat Pompeu Fabra. Centre de Cognició i Cervell) ; Roxin, Alex (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
Oscillatory activity robustly correlates with task demands during many cognitive tasks. However, not only are the network mechanisms underlying the generation of these rhythms poorly understood, but it is also still unknown to what extent they may play a functional role, as opposed to being a mere epiphenomenon. [...]

47 p, 1.4 MB The role of fixed delays in neuronal rate models / Montbrió, Ernest ; Roxin, Alex ; Centre de Recerca Matemàtica
Fixed delays in neuronal interactions arise through synaptic and dendritic processing. Previous work has shown that such delays, which play an important role in shaping the dynamics of networks of large numbers of spiking neurons with continuous synaptic kinetics, can be taken into account with a rate model through the addition of an explicit, fixed delay.

18 p, 268.1 KB On the existence of hysteresis in the Kuramoto model with bimodal frequency distributions / Montbrió, Ernest ; Pazó, Diego ; Centre de Recerca Matemàtica
We investigate the transition to synchronization in the Kuramoto model with bimodal distributions of the natural frequencies. Previous studies have concluded that the model exhibits a hysteretic phase transition if the bimodal distribution is close to a unimodal one, due to the shallowness the central dip. [...]
