[HTML][HTML] A brain model of altered self-appraisal in social anxiety disorder

AJ Jamieson, BJ Harrison, R Delahoy… - Translational …, 2023 - nature.com
The brain’s default mode network has a central role in the processing of information concerning
oneself. Dysfunction in this self-referential processing represents a key component of …

Dynamic subcortical modulators of human default mode network function

…, CG Davey, HS Savage, AJ Jamieson… - Cerebral …, 2022 - academic.oup.com
The brain’s “default mode network” (DMN) enables flexible switching between internally and
externally focused cognition. Precisely how this modulation occurs is not well understood, …

Dynamic neural interactions supporting the cognitive reappraisal of emotion

T Steward, CG Davey, AJ Jamieson… - Cerebral …, 2021 - academic.oup.com
The cognitive reappraisal of emotion is hypothesized to involve frontal regions modulating
the activity of subcortical regions such as the amygdala. However, the pathways by which …

[HTML][HTML] A thalamo-centric neural signature for restructuring negative self-beliefs

…, CG Davey, BA Moffat, RK Glarin, AJ Jamieson… - Molecular …, 2022 - nature.com
Negative self-beliefs are a core feature of psychopathology. Despite this, we have a limited
understanding of the brain mechanisms by which negative self-beliefs are cognitively …

[HTML][HTML] Subcortical contributions to salience network functioning during negative emotional processing

S Ince, T Steward, BJ Harrison, AJ Jamieson… - NeuroImage, 2023 - Elsevier
Core regions of the salience network (SN), including the anterior insula (aINS) and dorsal
anterior cingulate cortex (dACC), coordinate rapid adaptive changes in attentional and …

[HTML][HTML] Modulation of the brain's core-self network by self-appraisal processes

R Delahoy, CG Davey, AJ Jamieson, L Finlayson-Short… - NeuroImage, 2022 - Elsevier
The ‘core’ regions of the default mode network (DMN) – the medial prefrontal cortex (MPFC),
the posterior cingulate cortex (PCC), and inferior parietal lobules (IPL) – show consistent …

Rostral anterior cingulate network effective connectivity in depressed adolescents and associations with treatment response in a randomized controlled trial

AJ Jamieson, BJ Harrison, A Razi… - …, 2022 - nature.com
The rostral anterior cingulate cortex (rACC) is consistently implicated in the neurobiology of
depression. While the functional connectivity of the rACC has been previously associated …

[HTML][HTML] Frontoamygdalar effective connectivity in youth depression and treatment response

PH Kung, CG Davey, BJ Harrison, AJ Jamieson… - Biological …, 2023 - Elsevier
Background Emotion regulation deficits are characteristic of youth depression and are
underpinned by altered frontoamygdalar function. However, the causal dynamics of …

Differential modulation of effective connectivity in the brain's extended face processing system by fearful and sad facial expressions

AJ Jamieson, CG Davey, BJ Harrison - Eneuro, 2021 - eneuro.org
The processing of emotional facial expressions is underpinned by the integration of information
from a distributed network of brain regions. Despite investigations into how different …

A distinct intra-individual suppression subnetwork in the brain's default mode network across cognitive tasks

CA Leonards, BJ Harrison, AJ Jamieson… - Cerebral …, 2023 - academic.oup.com
Suppression of the brain’s default mode network (DMN) during external goal-directed
cognitive tasks has been consistently observed in neuroimaging studies. However, emerging …
