Noisy neural nets exhibiting memory domains.
Previous studies with probabilistic neural nets in which the neural connections are set up by means of chemical markers, revealed the existence of multiple memory domains. We generalized these studies by considering the intrinsic noise of the systems, caused by the spontaneous release of synaptic transmitter substance. A simple mathematical model is developed, which yields characteristics of multiple memory domains analogous to those occurring in noiseless nets.
