Table 4.

The loadings of neurons on the components extracted during stage 1 of the PCA based categorization procedure for slow phasic firing rate patterns. The first four components retained for the final PCA solution in the Stage 2 analysis are associated with approximately 65% of the total variance among all neurons.
