Evidence for the standard model, multiple trace theory, or the unified theory? [0.03%]
标准模型、多踪迹理论还是统一理论的证据?

There have been two dominating theories for memory consolidation: the standard model (SM) and multiple trace theory (MTT). Whereas lesion studies have largely indicated a waning role for the hippocampus in memory consolidation, and thus hav...
The devil may be in the details: The need for contextually rich stimuli in memory consolidation research [0.03%]

Systems consolidation theory (SCT) proposes that the hippocampus is not required for retrieval of remote memories. In this issue, Tallman and colleagues observe reduced hippocampal-cortical connectivity in recognition memory as a function o...
Specifying 'where' and 'what' is critical for testing hippocampal contributions to memory retrieval [0.03%]
测试海马体对记忆检索的贡献时确定"在哪里"和"是什么"至关重要

Tallman and colleagues' review of consolidation studies found that the length of the delay between 'recent' and 'remote' events is an influential determinant of detecting temporally graded hippocampal activity. Here, we discuss two addition...

Tallman and colleagues (this issue) showed that memory consolidation of laboratory materials produces, even at short intervals, changes in cortical activity within a widespread network of brain regions. These changes, however, do not encomp...

Tallman and colleagues (this issue) report fMRI findings in support of the classic view of memory consolidation over its main challenger, the multiple trace theory. The present commentary highlights some of the obstacles facing any fMRI stu...
These things take time: what is the role of the hippocampus in recognition memory over extended delays? [0.03%]

In a clever experimental design, Tallman, Clark, and Smith (this issue) tested the changes in fMRI activation and functional connectivity in the hippocampus and cortex as a function of memory age. They found that activation changed accordin...
The contributions of eye gaze fixations and target-lure similarity to behavioral and fMRI indices of pattern separation and pattern completion [0.03%]

Pattern separation and pattern completion are generally studied in humans using mnemonic discrimination tasks such as the Mnemonic Similarity Task (MST) where participants identify similar lures and repeated items from a series of images. F...
Is loss avoidance differentially rewarding in adolescents versus adults? Differences in ventral striatum and anterior insula activation during the anticipation of potential monetary losses [0.03%]
青少年和成人避免损失的动机不同吗?在潜在金钱损失预期过程中腹侧纹状体及前绝缘皮层激活特点的差异性

Avoiding loss is a crucial, adaptive guide to human behavior. While previous developmental research has primarily focused on gaining rewards, less attention has been paid to loss processing and its avoidance. In daily life, it is often unkn...
Sensitivity of the hippocampus to objective but not subjective episodic memory judgments [0.03%]

We assessed whether neural activity in the hippocampus dissociates according to whether memory test items elicit a subjective sense of recollection or accurate retrieval of contextual information. We reanalyzed a previously acquired dataset...
Perceived stress and rejection associated with functional network strength during memory retrieval in adolescents [0.03%]

The brain undergoes substantial structural and functional remodeling during adolescence, including alterations in memory-processing regions influenced by stress. This study evaluated brain activation using functional magnetic resonance imag...
