Neuronal correlations. (A) Correlation of fluorescence signals for each neuron–neuron pair from the intensity traces in figure 2A at 0% (left), 4% (middle), and 8% (right) isoflurane. The color scale is red when a correlation exists, blue when anticorrelated, and white when no correlation is found. The leading diagonal is red because each neuron is correlated to itself by definition. (B) Distributions of all correlation values measured at each level of isoflurane. (Inset) Mean correlation values at each level of isoflurane. Sample variability reported as SD. (***P < 0.0001).
