Abstract

We present a novel viewpoint on the complexity of neural mechanisms, addressing some aspects of cortical processing, like memory, context modulation and coherence. Our simulation studies show how relatively small, recurrent microcircuits can interact with populations of neurons, achieving spontaneous memory / recall effects. Here,context modulation can play an important part in the conditioned recall. The emphasis is on the dynamical self-sustained activity of the recurrent microcircuit viewed as a "mental state" which can be interpreted by a target output population and controlled by external waves of activity (mainly external inhibitory waves). We also consider the problem of selforganization and dynamical interaction between neuronal populations, which could have a key role in inference, memory and behavior.
