↵^a The first column lists the cortical area. The second column is the total number of recording sites for each area. The third column is the number of sites with nonuniform, spike-field phase distributions, indicating a preferred phase (Rayleigh test, p < 0.05). The last column is the number of sites with nonuniform phase distributions and a preferred phase that is within ±90° (circular mean) of the LFP trough (180°). Areal abbreviations follow the nomenclature of Paxinos et al. (1999) with the exception of dPFC and vPFC: 6DR, Dorsorostral area 6; 8AD, anterodorsal area 8; 8B, area 8B; dPFC, dorsal prefrontal cortex; vPFC, ventral prefrontal cortex; 9L, lateral area 9; PEC, caudal area PE; PGM, medial area PG; PE, area PE; PG, area PG; MIP, medial intraparietal area; LIP, lateral intraparietal area.
