word sequences into ‘neural sentences’. Since oscillator readers are a collective product of neuronal cooperation, their occurrence is reflected in the LFP. Therefore, along with other intermittent population events, such as K-complexes, ponto-geniculo-occipital (PGO) spikes and hippocampal sharp waves, LFP rhythms can be used conveniently as mesoscopic reader mechanisms by the experimenter. Assemblies active within a given classifier pattern, such as an oscillation cycle, can represent an integrated entity (e.g., a neural word).
