Both analytic approaches also provide weaker evidence for a relation between the fMRI and low frequency LFP power, with a trend to colocalization in the 8–15 Hz range and in the multiple linear regression analysis, 16–23 Hz range alone as a marginally significant regressor and the interaction of single neuron firing and 16–23 Hz power as a significant regressor.
