In experiments where DNQX, an AMPA receptor antagonist, was injected into the nucleus accumbens prior to systemic cocaine administration, it diminished the acquisition of this place preference, highlighting AMPA receptors' role in this process.
When DNQX, an AMPA receptor blocker, was administered into the nucleus accumbens before cocaine was given systemically, it reduced the development of a preference for that location, suggesting a crucial role for AMPA receptors in this behavior.
