{"title":"Memory Reconsolidation and Fear Extinction as Treatment of Trauma and PTSD: A Review","authors":"Gavin Du","doi":"10.70121/001c.154950","DOIUrl":"https://doi.org/10.70121/001c.154950","url":null,"abstract":"Intrusive and persistent fear memories are a defining feature of post-traumatic stress disorder (PTSD). Two processes have gained attention as alternatives to traditional therapies: memory reconsolidation, in which a recalled memory enters a labile state and can be modified, and fear extinction, in which new safety learning suppresses the original trace. This review examines eleven recent studies addressing both mechanisms and their clinical applications. Reconsolidation depends on protein synthesis, prediction error, and hippocampal-prefrontal coordination, and can be disrupted through pharmacological agents such as propranolol, rapamycin, and NMDA modulators, as well as neuromodulation. Extinction instead relies on building safety associations and is influenced by adrenergic state, sleep quality, and the salience of conditioned cues. Clinically, reconsolidation-based methods, including Reconsolidation of Traumatic Memories therapy and propranolol reactivation, show promise in weakening traumatic recall, while extinction-based approaches remain central to exposure therapies but often lead to relapse because patients must repeatedly face trauma. Together, the evidence suggests reconsolidation may allow more lasting change, whereas extinction provides reliable but fragile benefits. Future research should clarify boundary conditions and test integrated approaches to develop more durable, patient-centered PTSD treatments.","PeriodicalId":43806,"journal":{"name":"MASSACHUSETTS REVIEW","volume":"Winter 2025/2026 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.scholarlyreview.org/article/154950.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147907871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article identifies two trends in the Qing dynasty’s treatment of Vietnamese envoys during that time: a trend toward flexibility and moderation and, at other times, a trend toward toughness, even deterrence. However, the trend toward moderation prevailed throughout the nineteenth century. Then, the article elucidates the factors that contributed to this situation and highlights the relative power of China in the regional and global context in that era.","PeriodicalId":43806,"journal":{"name":"MASSACHUSETTS REVIEW","volume":"13 1","pages":"117-135"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenge underlying the hydrogen evolution reaction in electrochemical water splitting is to replace the noble metal-based electrocatalysts with effective low overpotential and kinetically favorable electrocatalysts. This research focused on the synthesis and modification of non-noble metal zeolitic imidazolate framework-based electrocatalysts. Using the heteroatom metal doping to improve electrocatalysts, Ni, Ce, Bi, and In are investigated as possible dopants. Herein, we successfully synthesized electrocatalysts combining CoM nanoalloy (M = Ni/Ce/In/Bi) with N-doped carbon nanostructure, denoted as CoM@NC. Among all synthesized electrocatalysts, CoNi@NC demonstrates to be the best HER electrocatalyst, with the lowest overpotential of 454.5mV at 10 mA cm-2 current density, Tafel slope of 86.3 mV dec-1, and stability for more than 10 hours. The composition and structures of CoNi@NC optimize its electron structure, increase active sites, and improve its onductivity and stability, which makes it a possible effective nonnoble metal HER electrocatalyst. This electrocatalyst provides a possible method to design and synthesize hydrogen evolution electrocatalysts that can replace noble metal-based electrocatalysts.","PeriodicalId":43806,"journal":{"name":"MASSACHUSETTS REVIEW","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.scholarlyreview.org/article/123593.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147911280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a current overview of foundational deep reinforcement learning frameworks is presented, primarily based on latest developments including DeepMimic, Residual Force Control (RFC), Adversarial Motion Priors (AMP), and Simulated Character Control for 3D Human Pose Estimation (SimPoE). DeepMimic applies reference motion data for learning control policies and can synthesize a high-fidelity of the corresponding complex motion. RFC resolves dynamics mismatches with the help of external residual forces that allow it to perform certain motions. AMP is a combination of reinforcement learning and generative adversarial networks that helps in policy learning from scarce data, while SimPoE is the integration of physics-based control with the 3D pose estimator for realism. The research focuses on exploring compatible uses of these technologies in ballet performance, from fine tuning of methods to mimic the exacting nature of artistic ballet movements to concerns of scalability, data integrity, and ethical considerations.","PeriodicalId":43806,"journal":{"name":"MASSACHUSETTS REVIEW","volume":"Fall 2024 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.scholarlyreview.org/article/123585.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
