The search of the code underlying the transmission of information through the different stages of integration of the brain is a very active investigation field. Here, the possible involvement in the neural code of global population oscillatory activities has been discussed. The behaviorally important rhythmic activities of the hippocampal CA3 field have been analyzed to this aim. The genesis and the features of such activities have been studied by the computer simulation of a model of the entire CA3. The simulation demonstrated the ability of the network of inhibitory interneurons to control nicely the transmission of activity through the pyramidal population. The results suggested that the hippocampal formation and the CA3 field—in particular—could be organized in a way to allow the passing of excitatory activities only during specific and narrow time windows, confined by inhibitory barrages possibly linked to attentional processes.
