Figure 6.

Under deep anesthesia precise spike-LFP locking is common. Examples showing that the waveforms of VmLFPcc and LFP STA in animals under deep halothane anesthesia are distinct. These two cells (which are shown only here and are not part of any other analysis) exhibit the case where a large portion of the spikes has a tight temporal relation with the LFP signal. The firing rates of the neurons were ∼6 Hz (A) and ∼1 Hz (B). The ratios between absolute peaks of LFP STA and VmLPFcc in the figure (after both were normalized to have the same Euclidian norm) are 2.1 and 2.3, respectively.
