Decreased PKA activity within the NAcc shell, but not core, facilitates partner preferences. Infusions of CSF (n = 8) resulted in nonselective side-by-side contact between partners and strangers. Intra-shell (n = 8), but not core (n = 8) administration of Rp (8 ng) induced a significant partner preference. Activation of PKA with Sp (8 ng) did not induce partner preferences when infused in either the shell (n = 8) or the core (n = 7). *p < 0.05, significantly more time with the partners compared with strangers. Error bars indicate SEM.
