Behavioral modulations of the sensory-motor coupling. (A) Rats displayed two main behaviors: remaining still and poking the nose at a hole in the cage wall (“NOSEPOKE”) or actively exploring the cage (“EXPLORE”). (B) Respiratory frequency time series, calculated from diaphragm EMG; note the large variance in frequency during exploratory periods relative to nose-poke periods (marked by gray bars). (C) Raw LFP time series. Note the much larger amplitudes, which represent primarily theta activity at this time scale, during exploration as compared to nose-poke. (D) Time-frequency chart of raw LFP spectral power. During the large amplitude LFP periods (C) both gamma and theta power are dramatically increased relative to nose-poke. (E) Time-frequency chart of LFP-rsEMG spectral coherence. The magnitude of coherence does not change across frequencies in the two conditions. (F) Example traces of raw LFP and rsEMG before and after a transition between both behavioral modes.
