[HTML][HTML] Predicting memory from the network structure of naturalistic events
When we remember events, we often do not only recall individual events, but also the
connections between them. However, extant research has focused on how humans segment and …

Variability in the analysis of a single neuroimaging dataset by many teams
Data analysis workflows in many scientific domains have become increasingly complex and
flexible. Here we assess the effect of this flexibility on the results of functional magnetic …

[HTML][HTML] Transforming the concept of memory reactivation
Reactivation refers to the phenomenon wherein patterns of neural activity expressed during
perceptual experience are re-expressed at a later time, a putative neural marker of memory. …

What can narratives tell us about the neural bases of human memory?
Highlights • Both encoding material and retrieval tasks can vary in terms of their narrative-ness.
• Narratives drive inter-individual neural synchrony in the default mode network. • …

Lower parietal encoding activation is associated with sharper information and better memory
Mean fMRI activation in ventral posterior parietal cortex (vPPC) during memory encoding often
negatively predicts successful remembering. A popular interpretation of this phenomenon …

Reconstructing perceived and retrieved faces from activity patterns in lateral parietal cortex
Recent findings suggest that the contents of memory encoding and retrieval can be decoded
from the angular gyrus (ANG), a subregion of posterior lateral parietal cortex. However, …

Hippocampal mismatch signals are modulated by the strength of neural predictions and their similarity to outcomes
The hippocampus is thought to compare predicted events with current perceptual input,
generating a mismatch signal when predictions are violated. However, most prior studies have …

Decomposing parietal memory reactivation to predict consequences of remembering
Memory retrieval can strengthen, but also distort memories. Parietal cortex is a candidate
region involved in retrieval-induced memory changes as it reflects retrieval success and …

A generalized cortical activity pattern at internally generated mental context boundaries during unguided narrative recall
Current theory and empirical studies suggest that humans segment continuous experiences
into events based on the mismatch between predicted and actual sensory inputs; detection …

Adding meaning to memories: How parietal cortex combines semantic content with episodic experience
H Lee, PA Keene, SC Sweigart… - Journal of …, 2023 - Soc Neuroscience
Neuroimaging studies of human memory have consistently found that univariate responses
in parietal cortex track episodic experience with stimuli (whether stimuli are 'old' or 'new'). …
