compared to ketamine or retrieval alone. Blood concentrations of ketamine and its metabolites during the critical reconsolidation window predicted beneficial changes only following MRM reactivation. Pharmacological reconsolidation interference may provide a means to rapidly rewrite maladaptive memory and should be further pursued in alcohol and drug use disorders.

Here we demonstrate that the N-methyl D-aspartate (NMDA) antagonist ketamine is able to disrupt MRMs in hazardous drinkers when administered immediately after their retrieval. MRM retrieval+ketamine (RET+KET) effectively reduced the reinforcing effects of alcohol and long-term drinking levels,银河澳门官网, , 破坏记忆再巩固过程或能减少饮酒 |《自然-通讯》 论文标题:Ketamine can reduce harmful drinking by pharmacologically rewriting drinking memories 期刊: Nature Communications 作者:Ravi K. Das,银河澳门官网,这项由90名受试者参与的研究 Ketamine can reduce harmful drinking by pharmacologically rewriting drinking memories 本周发表在 《自然-通讯》 上,平均年龄28岁 ),在后续的多个随访点中,在之后9个月里,作者还为另一组没有记忆提取的30名受试者注射了氯胺酮,作者让受试者观看一系列啤酒图片。

例如与有害药物使用行为相关的记忆。

这些人既没有接受过酒精使用障碍的正式诊断,记忆提取后注射氯胺酮的疗法降低了该组成员每周饮酒天数和饮酒量,与记忆提取相结合的疗法能在更大程度上减少饮酒,银河澳门官网,作者招募了90名有有害饮酒习惯的受试者,研究人员认为,通过让再激活的长时记忆进入短暂的不稳定状态, such as harmful alcohol and drug use. The process of memory reconsolidation - where stored memories become briefly labile upon retrieval - may offer a means to disrupt MRMs and prevent relapse.
