Enhanced brain activity associated with memory access in highly superior autobiographical memory
TLDR
FMRI investigation of a group of subjects identified as having HSAM provides evidence of interaction of brain systems engaged in memory retrieval and suggests that enhanced activity of these systems is selectively involved in enabling more efficient access to past experiences in HSAM.
Decoding fMRI Signatures of Real-world Autobiographical Memory Retrieval
TLDR
The neural patterns underlying memory for real-world autobiographical events are investigated at 1- to 3-week retention intervals as well as whether distinct patterns are associated with different subjective memory states, and the implications for neuroscientific accounts of episodic retrieval are discussed.
Individual Differences in Autobiographical Memory
Memory deficits in aphantasics are not restricted to autobiographical memory - Perspectives from the Dual Coding Approach.
TLDR
Evidence was obtained for the influence of visual imagery on all memory components beyond autobiographical memory as well as verbal short-term and long-term memory in congenital aphantasics and demographically matched controls.
The Neural Dynamics of Individual Differences in Episodic Autobiographical Memory
TLDR
It is proposed that superior subjective E-AM and visual EM are associated with greater similarity in static neural organization patterns, potentially indicating greater efficiency in switching, between rest and mental states relevant to encoding perceptual information.
Older adults with lower autobiographical memory abilities report less age-related decline in everyday cognitive function
TLDR
Congenitally low trait-level episodic AM may paradoxically confer a functional advantage in aging, due to well-developed non-episodic strategies not present in those with higher abilities, who are more sensitive to age-related memory decline attributable to medial temporal lobe changes.
Neurophysiological signatures in the retrieval of individual autobiographical memories of real-life episodic events
TLDR
A convolution network-based algorithm is implemented for the selection of the stimuli while monitoring participants’ memory retrieval with scalp EEG recordings over three periods of time after encoding (1 week, 2 weeks, and 6 to 12 months).

Autobiographical Memory and Patterns of Brain Atrophy in Frontotemporal Lobar Degeneration
TLDR
The pattern of episodic, but not semantic, autobiographical impairment was enhanced with disease progression on 1to 2-year follow-up testing in a subset of patients, supplementing the cross-sectional evidence for specificity of episodically rich autobiographical memory impairment with longitudinal data.

The functional neuroanatomy of autobiographical memory: A meta-analysis
False memories in highly superior autobiographical memory individuals
TLDR
It is suggested that HSAM individuals reconstruct their memories using associative grouping, as demonstrated by a word-list task, and by incorporating postevent information, as shown in misinformation tasks, and that malleable reconstructive mechanisms may be fundamental to episodic remembering.
The Functional Neuroanatomy of Episodic and Semantic Autobiographical Remembering: A Prospective Functional MRI Study
TLDR
A functional neuroanatomical dissociation between episodic and semantic autobiographical memory is supported, providing concordance to amnesic syndromes with disproportionate impairment in one of these two forms of autobiographicalmemory.
