When the brain, but not the person, remembers: Cortical reinstatement is modulated by retrieval goal in developmental amnesia
TLDR
This article found evidence of scene reinstatement effects in the parahippocampal and retrosplenial cortex that were equivalent to those shown by healthy controls in the presence of severe hippocampal atrophy.About:

Hippocampal ripples and their coordinated dialogue with the default mode network during recent and remote recollection.
TL;DR: In this paper, the authors uncover different profiles of ripple activity in the human hippocampus during the retrieval of recent and remote autobiographical events and semantic facts and reveal a key role for hippocampal ripples in orchestrating hippocampal-cortical communication across large-scale networks involved in conscious recollection.

Brain Mechanisms Underlying the Subjective Experience of Remembering
TL;DR: The ability to remember events in vivid, multisensory detail is a significant part of human experience, allowing us to relive previous encounters and providing us with the store of memories that shape our identity as mentioned in this paper .

The Hippocampal Horizon: Constructing and Segmenting Experience for Episodic Memory.
T W Ross,Alexander Easton +1 more
TL;DR: In this article, a unification of how these dynamic physiological mechanisms of the hippocampus relate to ongoing externally and internally driven event segmentation, facilitating the demarcation of specific moments during experience is presented.

Largely intact memory for spatial locations during navigation in an individual with dense amnesia
TL;DR: In this paper , an individual with severe retrograde and anterograde amnesia was tested in an immersive virtual environment and compared to age-matched controls, the individual with amnesia showed no significant deficits in navigation from either repeated or novel start points, although both the individual and controls performed well above chance at placing objects near their correct locations.

Automated Anatomical Labeling of Activations in SPM Using a Macroscopic Anatomical Parcellation of the MNI MRI Single-Subject Brain
Nathalie Tzourio-Mazoyer,B. Landeau,D. Papathanassiou,Fabrice Crivello,Octave Etard,Nicolas Delcroix,Bernard Mazoyer,Marc Joliot +7 more
TL;DR: An anatomical parcellation of the spatially normalized single-subject high-resolution T1 volume provided by the Montreal Neurological Institute was performed and it is believed that this tool is an improvement for the macroscopical labeling of activated area compared to labeling assessed using the Talairach atlas brain.

An automated method for neuroanatomic and cytoarchitectonic atlas-based interrogation of fMRI data sets
TL;DR: This paper provides a powerful method of probing fMRI data using automatically generated masks based on lobar anatomy, cortical and subcortical anatomy, and Brodmann areas based on an automated atlas-based masking technique.

Elements of episodic memory
TL;DR: In this paper, the authors present an EPISODIC/SEMANTIC DISTINCTION and a general overview of the ECPHORY system in a general framework.
Journal ArticleDOI
Why there are complementary learning systems in the hippocampus and neocortex: insights from the successes and failures of connectionist models of learning and memory.
TL;DR: The account presented here suggests that memories are first stored via synaptic changes in the hippocampal system, that these changes support reinstatement of recent memories in the neocortex, that neocortical synapses change a little on each reinstatement, and that remote memory is based on accumulated neocorticals changes.

Episodic Memory: From Mind to Brain
TL;DR: Episodic memory is a neurocognitive (brain/mind) system, uniquely different from other memory systems, that enables human beings to remember past experiences as discussed by the authors, which is a true, even if as yet generally unappreciated, marvel of nature.
