Sliding Global Attractors of Neural Learning and Memory

Abstract

The highly variable nature of neural firing has been recognized by diverse empirical and analytic findings. Here, the underlying morphology of neural firing is shown to be governed by a bilinear map, prescribing eight types of neuronal global attractors and their points of local bifurcation. While synaptic learning gives rise to irregular firing, membrane memory is shown to guarantee that, under the same external activation, learning and retrieval end at the same global attractor. Forced and spontaneous changes in membrane conductance are shown to cause sliding of the global attractors, switching them from passive to active state and vice versa, and creating secondary firing modes. Selective activation of interacting neurons is shown to create a shunting effect, yielding combinatorial retrieval, concealment and revelation of stored global attractors. The utility of the global attractors is explained not only by their individual dynamic characteristics, but also by their high power of combinatorial expression.
