Fig. 2From: Resilience, plasticity and robustness in gene expression during aging in the brain of outbred deer miceDiagrammatic depiction of the steps followed for the calculation of the composite correlation index (Pc). Person’s correlation R values of each gene with all other genes were calculated in samples of young and old animals respectively. Then the Pc value was calculated as the Person’s R of all R values of each gene between young and old animal samplesBack to article page
