Fig. 3From: Alterations in iron content, iron-regulatory proteins and behaviour without tau pathology at one year following repetitive mild traumatic brain injuryHeatmap of hierarchical clustering of samplesfor the top 50 most variable genes in the dataset. The colour key represents Z scores, where a value of 0 indicates average gene expression, -2 indicates underexpression and + 3 indicates overexpression. This heatmap further demonstrates clustering of genes by sexBack to article page
