Figure 1.

Population data showing the effects of cortical cholinergic stimulation on spontaneous MUA and FP activity in barrel cortex. A–C, The columns depict the results from three different sets of experiments testing four different doses of the cholinergic agonist CA between 50 and 2500 μm (A), six different doses of CA between 0.5 and 2500 μm (B), and two doses of the muscarinic antagonist AT (C). The top panels show the effects of the drugs on spontaneous MUA firing rate. The middle panels show the effects of the drugs on autocorrelations and cross-correlations of the spontaneous MUA. The bottom panel shows the effects of the drugs on the FFT power spectrum (10 ranges between 0 and 50 Hz) of the FP activity. Asterisks in the bottom panels denote frequency ranges for which any of the doses produced a significant effect compared with control (see text for details). The bottom panel of B shows only four of the six doses for clarity.
