Connectionists: A new paper on stochastic synchrony of chaos in PNN

[Takashi KANAMARU]

Dear all,

I would like to announce a new paper on
stochastic synchrony of chaos in PNN is available
from the following page.

"Stochastic synchrony of chaos in a pulse coupled neural network
with both chemical and electrical synapses among inhibitory neurons,"
Neural Computation, vol.20, no.8 (2008) pp.1951-1972.

[Abstract]
The synchronous firing of neurons in a pulse coupled
neural network composed of excitatory and inhibitory neurons
is analyzed. The neurons are connected by both chemical synapses
and electrical synapses among the inhibitory neurons.
By introducing electrical synapses, periodically synchronized firing
as well as chaotically synchronized firing is widely observed.
Moreover, we find stochastic synchrony where the ensemble-averaged
dynamics shows synchronization in the network but each neuron has
a low firing rate and the firing of the neurons seems to be stochastic.
Stochastic synchrony of chaos corresponding to a chaotic attractor
is also found.


Best regards,

Takashi KANAMARU
