Triggering off RPS in an intact chronic

The horizontal line (S) signals the stimulation of the pontine reticular formation (300/sec; 1 msec pulses; 0.8 V; bipolar) for 11 sec during SPS. Note the appearance of fast activity at the cortical and reticular level, the total disappearance of the EMG activity of the neck muscles (EMG), the acceleration and irregularity of the respiration (Resp), and the appearance of rapid eye movements (O). This RPS lasted for 10 min. The same phenomenon was reproduced five times in this session. The two recordings I and II are continuous.

  • CSM: Sensory motor cortex;
  • CA: Acoustic cortex;
  • FR: mesencephalic reticular formation.

Scale: 2 sec, 50 microV.

From Jouvet et al. (1960).
