hypothalamus), whereas GLYTCK showed a rather specific hippocampal expression for both occipital and Cz alpha power. Immune genes IL1RL1 and IL18R1 on chromosome 2 also reached the threshold for significance in the significant association with cortical and subcortical expression with alpha oscillations (see Figure 4). Note that the positional gene‐based test pointed to MTERF4 expression in the putamen reached significance for Cz alpha power.
