This study shows that ketamine blocks morphine-induced conditioned place preference and anxiety-like behaviors in mice, suggesting it may interfere with memory of morphine-context associations rather than just alleviating negative affective states.

This study shows that morphine reduces synaptic activity and increases intrinsic excitability in D2R-MSNs but not D1R-MSNs in the nucleus accumbens shell of mice.
