Task-residual functional connectivity of language and attention networks

Published in: Brain and Cognition, Volume 122, April 2018, 52-58 Abstract “Functional connectivity using task-residual data capitalizes on remaining variance after mean task-related signal is removed from a time series. The degree of network specificity in language and attention domains featured by task-residual and resting-state data types were compared. Functional connectivity based on task-residual data evidenced

Beyond Functional Connectivity: Investigating Networks of Multivariate Representations

Trends in Cognitive Sciences

Published in: Trends in Cognitive Sciences, Volume 22, Issue 3, 258 – 269 Abstract “A family of novel methods study the interactions between brain regions taking advantage of the information encoded in multivariate patterns of responses. Some of these methods additionally capture nonlinear interactions, offering insights into how representations are transformed from brain region to brain

Dynamic changes in large-scale functional network organization during autobiographical memory retrieval

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 208-224 Abstract “Autobiographical memory (AM), episodic memory for life events, involves the orchestration of multiple dynamic cognitive processes, including memory access and subsequent elaboration. Previous neuroimaging studies have contrasted memory access and elaboration processes in terms of regional brain activation and connectivity within large, multi-region networks. Although interactions between key memory-related regions

Different neural routes to autobiographical memory recall in healthy people and individuals with left medial temporal lobe epilepsy

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 26-36 Abstract “Individuals with medial temporal lobe epilepsy (mTLE) are poor at recalling vivid details from autobiographical memories (AM), instead retrieving gist-like schematic memories. Recent research has suggested that this impoverished recall in comparison to controls may reflect (1) differential engagement of anterior vs posterior regions of the hippocampus (HC) and/or (2) differences between the

Search and recovery of autobiographical and laboratory memories: Shared and distinct neural components

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 44-54 Abstract “Functional neuroimaging evidence suggests that there are differences in the neural correlates of episodic memory for laboratory stimuli (laboratory memory) and for events from one’s own life (autobiographical memory). However, this evidence is scarce and often confounded with differences in memory testing procedures. Here, we directly compared the neural

Task-related and resting-state fMRI identify distinct networks that preferentially support remembering the past and imagining the future

Neuropsychologia

Published in: Neuropsychologia, Volume 110, February 2018, 180-189 Abstract “The relation between episodic memory and episodic future thought (EFT) remains an active target of research. A growing literature suggests that similar cognitive processes and neural substrates tend to support these acts. However, direct comparisons of whole-brain activity reveal clear differences, with numerous regions more active when engaging in
