Expression of selected genes in the hippocampal-parahippocampal area of the brain in Red Junglefowl (RJF) and White Leghorns (WL). Mean values are given as horizontal lines, and each individual's value is shown as a marker. Birds sampled at baseline conditions are colored blue (gray on black and white print), and birds sampled after 45 min of restraint stress are colored red (black on black and white print). Genes shown are early growth response 1 (EGR1), FK506 binding protein 5 (FKBP5), corticosterone-releasing hormone receptor 1 (CRHR1) and glucocorticoid receptor (GR).
