Brain responses to happy and sad own-infant faces, contrasting mothers with Type A (insecure/dismissing) and B (secure) attachment classifications (mean beta values ± sem) (a) Type B mothers show greater activation of the ventral striatum (VS; t = 3.1, P < 0.005) and medial prefrontal cortex (mPFC; t = 3.0, P < 0.01) in response to happy own-infant faces. (b) Type B mothers show greater activation of the right ventral striatum (t = 3.0, P < 0.01) in response to sad own-infant faces. Type A mothers show greater activation of the right anterior insula (t = -3.9, P < 0.0005).
