A case-matched study of neurophysiological correlates to attention/working memory in people with somatic hypervigilance.

Objective: Somatic hypervigilance describes a clinical presentation in which people report more, and more intense, bodily sensations than is usual. Most explanations of somatic hypervigilance implicate altered information processing, but strong empirical data are lacking. Attention and working memory are critical for information processing, and we aimed to evaluate brain activity during attention/working memory tasks in people with and without somatic hypervigilance.

The TWIN-E project in emotional wellbeing: study protocol and preliminary heritability results across four MRI and DTI measures.

Despite the significant advancements being made in the neurogenetics for mental health, the identification and validation of potential endophenotype markers of risk and resilience remain to be confirmed. The TWIN-E study (The Twin study in Wellbeing using Integrative Neuroscience of Emotion) aims to validate endophenotype markers of mental health across cognitive, brain, and autonomic measures by testing the heritability, clinical plausibility, and reliability of each of these measures in a large adult twin cohort. The specific gene and environmental mechanisms that moderate prospective links between endophenotype-phenotype markers and the final outcome of wellbeing will also be identified.

An integrative assessment of brain and body function 'at rest' in panic disorder: a combined quantitative EEG/autonomic function study.

We conducted a quantitative electroencephalographic (QEEG) and autonomic assessment of panic disorder (PD). The study samples comprised 52 individuals meeting DSM-IV criteria for PD (with or without agoraphobia) and 104 age-, gender-, and handedness-matched controls. EEG data were acquired from 16 scalp sites during resting eyes-open (REO) and eyes-closed (REC) conditions, and spectral power was assessed within 4 frequency bands: theta, alpha-1, alpha-2, and beta.

Event-related potential and autonomic signs of maladaptive information processing during an auditory oddball task in panic disorder.

Various empirical data suggest that individuals with Panic Disorder (PD) fail to appropriately assign significance to sensory stimuli within the internal and external milieu, including those stimuli which are patently threat-neutral. The failure to appropriately discriminate 'signal' stimuli from among 'noise' signals [Gordon, E., Liddell, B.
