Interneurons expressing α7 nACh mRNA or CCK immunoreactivity were counted in 21 sections from three different rats.
a
For each layer, the percentage of interneurons co-expressing α7 nACh mRNA and CCK immunoreactivity was calculated from the population of α7 nACh mRNA expressing interneurons.
b
For each layer, the percentage of interneurons co-expressing α7 nACh mRNA and CCK immunoreactivity was calculated from the population of CCK interneurons.
