In freely moving cats, the influence of atropine sulphate upon hippocampal theta activity was studied during paradoxical sleep (PS) and waking states, in relation to the associated eye movement (EM). The theta activity observed during immobility in the waking cat was completely abolished by atropine, while it was partially distorted during body movements and PS which produced higher theta frequency. The drugs inhibitory effect was little observed when the EM rate was highest. The mean frequency of the remaining theta waves was identical to that of the control state. Furthermore, atropine failed to affect EM rates during PS and it had on effect no isolated PGO waves, identified from the occipital data during PS.
