GSTZ1 and Anxiety: Finally, traits relating to pain sensitivity, activity, and anxiety are significantly correlated with Gstz1 expression in hippocampus, including activity after the first and second tone-shock pairing in the fear conditioning paradigm (record ID = 11914, r = 0.42, n = 54; 11915, r = 0.45, n = 54), response to mechanical nociception (record ID = 11823, r = -0.42, n = 55), and novel open field activity (record ID = 10916, r = 0.67, n = 17).
