Abstract :
A mathematical model is developed to characterize the aggregate behavior of large neural networks. The model describes the global effects of weight changes brought about by a local Hebb-type adaptation rule. In particular, such adaptation can lead to rhythmic behavior of ensemble activity even in an isolated cell assembly of homogeneous cells. Conditions that make such oscillatory behavior possible are identified, and the frequency, amplitude and center of oscillation are quantitatively related to the network parameters. Results from computer simulation of a 100-neuron assembly agree closely with the mathematical predictions
