Running head: Spontaneous and selective activity 2 SUMMARY AND CONCLUSIONS 1. We investigate the conditions under which cortical activity alone makes spontaneous activity self-reproducing and stable against uctuations of spike rates. Invoking simple assumptions about properties of integrate-and-re neurons it is shown that the stochastic background activity, of 1-5 spikes/second, cannot be stabi...

Analog circuits and and their interconnections, broadly called analog systems, are indispensable components of modern communication and electronic systems as well as electronic converters used in power systems. Almost all such circuits are built using active devices which require an external excitation for their operation. Active devices exhibit large sensitivity of performance to variations of...
