Dynamical synapses and attractor neural networks

[Bert Kappen]

Dear all,

I would like to announce the following paper, that will appear in 
one of the forthcoming issues of Neural Computation:

Associative Memory with dynamic synapses
Lovorka Pantic, Joaquin Torres, Bert Kappen and Stan Gielen

We have examined a role of dynamic synapses in the
stochastic Hopfield-like network behaviour. Our results
demonstrate an appearance of a novel phase characterized by quick
transitions from one memory state to another. The network is able
to retrieve memorized patterns corresponding to classical
ferromagnetic states but switches between memorized patterns with
an intermittent type of behaviour. This phenomenon might reflect
the flexibility of real neural systems and their readiness to
receive and respond to novel and changing external stimuli.
