Environmental enrichment (EE) has been shown to produce beneficial effects in addiction disorders; however, due to its configurational complexity, the underlying mechanisms are not yet fully elucidated. Recent evidence suggests that EE, acting as a metaplastic agent, may affect glutamatergic mechanisms underlying appetitive memory and, in turn, modulate reward-seeking behaviours: here, we have investigated such a possibility following a brief EE exposure.

短暂暴露于丰富的环境中可快速塑造大鼠大脑中的谷氨酸突触：化生指纹

环境浓缩（EE）已被证明对成瘾障碍产生有益的影响；然而，由于其配置的复杂性，其潜在机制尚未完全阐明。最近的证据表明，EE 作为化生剂，可能会影响食欲记忆的谷氨酸能机制，进而调节寻求奖励的行为：在这里，我们在短暂接触 EE 后研究了这种可能性。
