•Cortical theta oscillations are organized into bilaterally-symmetric spatiotemporal modes that span the neocortex.•The dominant mode appears as a divergent traveling wave that originates in retrosplenial cortex and is correlated with mouse speed.•Secondary modes are asynchronous spiral waves centered over somatosensory cortex.•Secondary modes become prominent during transient drops in synchrony that underlie a phase reset of the dominant mode.•We hypothesize that spiral waves may provide a mechanism to exert large-scale phase separability, and assimilate information into ongoing multisensory processing across the neocortex.
