J. M. Cortes, P. L. Garrido, J. Marro and J. J. Torres. Switching between memories in neural automata with synaptic noise. Neurocomputing 58-60: 67-71, 2004 [pdf] We present a stochastic neural automata in which activity fluctuations and synaptic intensities evolve at different temperature, the latter moving through a set of stored patterns. The network thus exhibits various retrieval phases, including one which depicts continuous switching between attractors. The switching may […]
J.M. Cortes, T.J. Sejnowski and M.C.W. van Rossum. Reverse Engineering: Weight dynamics consistent with experimental weight distributions. Society for Neuroscience Annual Meeting 2007 The strengths of synaptic connections that are responsible for perception and memory change on time scales ranging from milliseconds to many days. A key question is how memories can be made stable over long periods of time despite the ongoing synaptic plasticity. The distribution of synaptic weights […]
D. Marinazzo, J.M. Cortes, M. Postlethwaite and M. Hennig. Synaptic depression and multi-scale phenomena. Society for Neuroscience Annual Meeting 2007 How short term plasticity (STP) affects synaptic transmission has been widely studied during the last decade (Zucker and Regehr, 2001). During repetitive stimulation, a postsynaptic response can be facilitated or depressed or shaped by a combination of both. These effects have been successfully explained by models focusing on two main […]

Biophysical Society: 51th Annual Meeting. Biophysical Journal 257A-257A Suppl. S, 2007 In normal rat kidney (NRK) fibroblasts the excitable membrane exhibits action potentials caused by an intracellular, IP3-mediated calcium oscillation (CaO). We modeled that process in detail and applied bifurcation analysis to investigate the dynamic behaviour of […]
