2015b, The MathWorks, Inc., Natick, Massachusetts, USA). The same correlation analysis was performed for the mouse homologous Chrm3 among six types of single neurons. The adjusted P-value for significance was 0.05/(10*24) = 2 × 10−4 for the co-expression analysis with 10 brain tissues for 24 genes, and in the co-expression analysis of 6 mouse GABAergic neurons for 14 genes, the adjusted significance P-value was 0.05/(6*14) = 5 × 10−4.
