However, when we analyzed PV expression levels separately for spiny and non-spiny PVIs, we found a highly significant shift in behaviorally induced PV expression in spiny but not in non-spiny PVIs (p = 0.0042 in spiny versus p = 0.33 in non-spiny PVIs; Figure 4 A), suggesting that spiny and non-spiny PVIs differ in their susceptibility to experience-induced changes in gene expression.
