Summary: The act of remembering everyday experiences affects our perception of the world, future thinking, and self-perception. However, the ability to recall specific details and relive the past tends to decline with age. To address this, a smartphone application called HippoCamera was developed to help older adults enhance their episodic memory. By repeatedly reactivating memories of real-world events, participants experienced improved recollection and more positive emotions. These benefits were observed shortly after the intervention and even after a 3-month delay.

Summary: Successful inference can alter representations of overlapping events and lead to false memories by integrating features associated with overlapping events in memory. This integration can result in misattribution of contextual details across related events.

Summary: The continuous flow of experience in real-life events is condensed into a series of event segments separated by temporal discontinuities. The posterior medial network plays a key role in representing the dynamic unfolding of these event segments.

Summary: Highly superior autobiographical memory (HSAM) refers to individuals' ability to recall personal events, dates, and news events with detailed accuracy. Research suggests that HSAM retrieval largely reflects parallel processing rather than a temporal-based system. Additionally, HSAM individuals show superior memory for semantic information, which may be attributed to attaching autobiographical memories to these details.

Summary: Memory encoding and retrieval are important processes in episodic memory, with the hippocampus playing a key role. However, the connectivity between the hippocampus and neocortex during memory processing in humans is not well understood. This study used data from two large-scale functional resonance imaging studies to identify hippocampal-cortical networks active during memory tasks. The functional connectivity maps were similar during resting state, encoding, and retrieval, and the connectivity profiles of the anterior and posterior hippocampus were stable across different states. During retrieval, the hippocampal connectivity with areas involved in recollection increased, while encoding connectivity likely reflected contextual factors.

Summary: Depression is associated with lower specificity in autobiographical memories, which may not only be due to difficulties in focusing on event details, but also to broader memory deficits and weakened memory traces with the passage of time. These findings have important implications for memory interventions and treatments in depression.

Summary: This study utilizes a large dataset from social media to investigate the neural substrates of autobiographical memories. The research finds tight interconnections among memory features and identifies a multidimensional topography in the medial parietal cortex that reflects memory content, age, and strength.

Summary: Studies of epilepsy patients provide insights into the neuroscience of human memory. The impairment of remote memory in patients may result from the interaction of multiple factors, including hippocampal dysfunction. The lateralization of remote memory has been the focus of research, with left temporal lobe epilepsy patients experiencing more severe deficits than others.

Summary: Recent literature on sex-related differences in autobiographical memory emphasizes the importance of psychosocial factors like gender identity over biological sex. This fMRI study found gender identity to have a stronger impact on autobiographical memory than biological sex, highlighting the need to consider hormonal factors in future research. The results suggest an interaction between biological sex and gender identity in explaining variations in autobiographical memory.

Summary: Mounting evidence suggests distinct functional contributions of the anterior and posterior hippocampus to autobiographical memory retrieval, but how these subregions function under different retrieval demands as memories age is not yet understood.

Summary: Decreased fidelity of mnemonic representations plays a critical role in age-related episodic memory deficits, yet the brain mechanisms underlying such reductions remain unclear. Using functional and structural neuroimaging, this study found that changes in the hippocampus and the angular gyrus may underpin loss of memory precision in older age. The age-related reduction in activity reflecting successful recovery of object features was observed in the hippocampus, while the modulation of BOLD signal by graded memory precision was diminished in the angular gyrus.

Summary: Recollection of personal past events differs across the lifespan, with older individuals recalling fewer episodic details and conveying more semantic information than young. This study examines the relationship between gray matter volumes in temporal lobe regions (hippocampus and temporal poles) and age differences in autobiographical recollection. The findings show that older adults have smaller gray matter volumes in the posterior hippocampus and display less episodic and more semantic autobiographical memory compared to younger adults. Age-related associations between temporal pole volumes and episodic autobiographical recall were also observed in older adults, while in younger adults, temporal pole volume was correlated with performance on standard laboratory measures of semantic memory. Exploratory analyses further revealed that the relationship between age-related episodic autobiographical memory and anterior hippocampal volumes was dependent on sex. These findings suggest that age differences in brain structures implicated in episodic and semantic memory may indicate neural circuit reorganization to support autobiographical memory in later life.

Summary: Repeated retrieval of novel or imagined events reduces activity in brain regions critical for constructing mental scenarios, and this effect is also present when recollecting autobiographical memories. Specifically, the anterior hippocampus and vmPFC show decreased activity with repeated retrievals, while other brain regions take on different functions.

Summary: Neural overlap between autobiographical memory retrieval and personal problem solving occurs during the generation phase, driven by common retrieval demands, rather than solely in the context of detailed simulation.

Summary: The study compares the retrieval and elaboration abilities of young and older adults in reconstructing episodic autobiographical memories (EAMs). Older adults engage less in direct retrieval and more often end generative retrieval at general events rather than specific EAMs. The ability to elaborate internal details in EAMs is positively associated with the use of generative retrieval for reconstruction in both age groups.

Summary: This study tested the hypothesis that people adopt a third-person perspective in recall, using a perceptual out-of-body illusion during the encoding of real events. The results showed that an out-of-body experience leads to more third-person perspective during recollection.

Summary: This study suggests that language context influences the hippocampus-dependent event construction process during inner narration, especially for events simulating self-location in space. Additionally, the language used for inner narration also mediates hippocampal functional connectivity in bilingual individuals.
