✦ Synopsis


Figure 1 (A) PC-MC microcircuitry showing the disynaptic pathway between the PC mediated by MC showing frequency dependent recuitment and frequency dependent disynaptic inhibition of PC. (B) Raster plot (top) and average firing rate (bottom) of all the cells. The cells are colourcoded: PC (blue), BC (red) and MC (green).

We present an analysis of the attractors of a deterministic dynamics in formal neural networks characterized by binary threshold units and a nonsymmetric connectivity. It is shown that in these networks a stored pattern or a pattern sequence is represented by a cloud of attractors rather than by a s
