Bump formation in a binary attractor neural network
Kostadin Koroutchev, Elka Korutcheva
This paper investigates the conditions for the formation of local bumps in the activity of binary attractor neural networks with spatially dependent connectivity. We show that thes…

System size resonance in an attractor neural network
M. A. de la Casa, E. Korutcheva, J. M. R. Parrondo +1
We study the response of an attractor neural network, in the ferromagnetic phase, to an external, time-dependent stimulus, which drives the system periodically two different attrac…

Conditions for the emergence of spatial asymmetric states in attractor neural network
Kostadin Koroutchev, Elka Korutcheva
In this paper we show that during the retrieval process in a binary symmetric Hebb neural network, spatial localized states can be observed when the connectivity of the network is…
