Neuronal mechanisms for sequential activation of memory items: dynamics and reliability
Elif Köksal-Ersöz, Carlos Aguilar, Pascal Chossat +2
In this article we present a biologically inspired model of activation of memory items in a sequence. Our model produces two types of sequences, corresponding to two different type…
Pseudo-simple heteroclinic cycles in
Pascal Chossat, Alexander Lohse, Olga Podvigina
We study pseudo-simple heteroclinic cycles for a -equivariant system in with finite , and their nearby dynamics. In particular, in a first step towards a fu…
Latching dynamics in neural networks with synaptic depression
Pascal Chossat, Martin Krupa, Frédéric Lavigne
Priming is the ability of the brain to more quickly activate a target concept in response to a related stimulus (prime). Experiments point to the existence of an overlap between th…
Asymptotic stability of pseudo-simple heteroclinic cycles in R^4
Olga Podvigina, Pascal Chossat
Robust heteroclinic cycles in equivariant dynamical systems in R^4 have been a subject of intense scientific investigation because, unlike heteroclinic cycles in R^3, they can have…
Heteroclinic cycles in Hopfield networks
Pascal Chossat, Martin Krupa
Learning or memory formation are associated with the strengthening of the synaptic connections between neurons according to a pattern reflected by the input. According to this theo…
Simple heteroclinic cycles in R^4
Olga Podvigina, Pascal Chossat
In generic dynamical systems heteroclinic cycles are invariant sets of codimension at least one, but they can be structurally stable in systems which are equivariant under the acti…
