Arousal dissociates amygdala and hippocampal fear responses: evidence from simultaneous fMRI and skin conductance recording
…, ML Phillips, MJ Brammer, D Skerrett, J Lagopoulos… - Neuroimage, 2001 - Elsevier
The experience and appraisal of threat is essential to human and animal survival. Lesion
evidence suggests that the subjective experience of fear relies upon amygdala-medial
frontal activity (as well as autonomic arousal), whereas the factual context of threat stimuli …

[HTML][HTML] Subcortical brain alterations in major depressive disorder: findings from the ENIGMA Major Depressive Disorder working group
…, H Völzke, D Hoehn, M Czisch, J Lagopoulos… - Molecular …, 2016 - nature.com
The pattern of structural brain alterations associated with major depressive disorder (MDD)
remains unresolved. This is in part due to small sample sizes of neuroimaging studies
resulting in limited statistical power, disease heterogeneity and the complex interactions …

A double-blind, sham-controlled trial of transcranial direct current stimulation for the treatment of depression
Two recent sham-controlled studies found that transcranial direct current stimulation (tDCS)
was an effective treatment for depression. As tDCS is painless, relatively safe and
inexpensive, its efficacy in treating depression warrants further investigation. This double …

Diffuse axonal injury in severe traumatic brain injury visualized using high-resolution diffusion tensor imaging
J Xu, IA Rasmussen, J Lagopoulos… - Journal of …, 2007 - liebertpub.com
Traumatic brain injury (TBI) is the most common cause of death and disability in young
people. The functional outcome in patients with TBI cannot be explained by focal pathology
alone, and diffuse axonal injury (DAI) is considered a major contributor to the neurocognitive …

Cognitive generation of affect in bipolar depression: an fMRI study
Individuals with bipolar disorder manifest the full spectrum of emotions ranging from
depression to mania. In attempting to understand the functional substrates of mood we
attempted to identify brain regions associated with the cognitive generation of affect in …
