Among the 72 genes, we found that the expression of neuronal genes associated with nociception (OPRL1), excitotoxicity (GRIA2 and ARHGEF9), and behavioral locomotion and anxiety (HTR1D) were upregulated under psychological stress in the 1 en% LA diet animals, while downregulated in the 8 en% LA diet group. This evidence concerns the gene OPRL1 and Anxiety.
