Each row provides the correlation value for each SUA/LFP response property listed on the left column, followed by the p value and number of recordings. Both the SUA and LFP goodness of fit had to be ≥0.6 for each frequency band to be included in the correlation analysis. Significant differences are highlighted in bold. LGF, Low-gamma frequency; HGF, high-gamma frequency.
