Differential expression of spatiotemporal sleep spindle clusters in ageing

Liisa Raud, Martijn J.B. Smits, Markus Handal Sneve, Hedda T Ness, Line Folvik, Björn Rasch, Anders M. Fjell

This study identifies spatiotemporal sleep spindle clusters in aging and finds age-related changes in their expression and association with memory performance.

Network Segregation During Episodic Memory Shows Age-Invariant Relations with Memory Performance From 7 to 82 Years

Håkon Grydeland, Markus Handal Sneve, James M. Roe, Liisa Raud, Hedda T Ness, Line Folvik, Inge K. Amlien, Oliver Marcel Geier, Øystein Sørensen, Dídac Vidal-piñeiro A, Kristine Beate Walhovd, Anders M. Fjell

The paper examines how brain network segregation relates to episodic memory performance across age, finding age-invariant associations between functional connectivity and memory.

Hippocampal-cortical functional connectivity during memory encoding and retrieval

Liisa Raud, Markus Handal Sneve, Dídac Vidal-piñeiro A, Øystein Sørensen, Line Folvik, Hedda T Ness, Athanasia M. Mowinckel, Håkon Grydeland, Kristine Beate Walhovd, Anders M. Fjell

This study identifies stable and task-specific hippocampal-cortical connectivity patterns during memory encoding and retrieval using fMRI data from two large-scale studies.

Sustained upregulation of widespread hippocampal-neocortical coupling following memory encoding

Line Folvik, Markus Handal Sneve, Hedda T Ness, Dídac Vidal-piñeiro A, Liisa Raud, Oliver Marcel Geier, Kristine Beate Walhovd, Anders M. Fjell

The paper investigates hippocampal-neocortical coupling after memory encoding and finds widespread upregulation of functional connectivity during post-encoding rest, suggesting broader reactivation beyond perceptual aspects.

Whole-brain connectivity during encoding: age-related differences and associations with cognitive and brain structural decline

Elettra Capogna, Markus Handal Sneve, Liisa Raud, Line Folvik, Hedda T Ness, Kristine Beate Walhovd, Anders M. Fjell, Dídac Vidal-piñeiro A

The paper examines age-related changes in whole-brain connectivity during memory encoding and links these changes to cognitive and brain structural decline.
