When extreme, anxiety--a state of distress and arousal prototypically evoked by uncertain danger--can become debilitating. Uncertain anticipation is a shared feature of situations that elicit signs of anxiety across disorders, species, and assays. Despite the profound significance of anxiety for human health and wellbeing, the neurobiology of uncertain threat anticipation remains remarkably unsettled. Leveraging a paradigm adapted from animal research and optimized for functional MRI, we examine...

In two studies with college student participants, we explored the ways in which worry and rumination may be similar or distinct. Towards that end, as part of our research, we developed new laboratory measures of worry and rumination. In Study 1, we examined how the new lab instruments we developed differentiate worry versus rumination and initiation versus termination. We did so by comparing them with two other measurement methods of worry and rumination, ecological momentary assessment and ques...

Abstract When extreme, anxiety can become debilitating. Anxiety disorders, which often first emerge early in development, are common and challenging to treat, yet the underlying mechanisms have only recently begun to come into focus. Here, we review new insights into the nature and biological bases of dispositional negativity, a fundamental dimension of childhood temperament and adult personality and a prominent risk factor for the development of pediatric and adult anxiety disorders. Converging...

Alcohol use is common, imposes a staggering burden on public health, and often resists treatment. The central extended amygdala (EAc)—including the bed nucleus of the stria terminalis (BST) and the central nucleus of the amygdala (Ce)—plays a key role in prominent neuroscientific models of alcohol drinking, but the relevance of these regions to acute alcohol consumption in humans remains poorly understood. Using a single-blind, randomized-groups design, multiband fMRI data were acquired from 49 ...

Alcohol abuse is common, imposes a staggering burden on public health, and is challenging to treat, underscoring the need to develop a deeper understanding of the underlying neurobiology. When administered acutely, ethyl alcohol reduces threat reactivity in humans and other animals, and there is growing evidence that threat-dampening and related negative reinforcement mechanisms support the etiology and recurrence of alcohol and other kinds of substance misuse. Converging lines of evidence motiv...

Spatial normalization, the process of aligning anatomical or functional data acquired from different individuals to a common stereotaxic atlas, is routinely used in the vast majority of functional neuroimaging studies, with important consequences for scientific inference and reproducibility. Although several approaches exist, multi-step techniques that leverage the superior contrast and spatial resolution afforded by T1-weighted anatomical images to normalize echo planar imaging (EPI) functional...

ABSTRACTAlthough there has been steady progress elucidating the influence of emotion on cognition, it remains unclear precisely when and why emotion impairs or facilitates cognition. The present study investigated the mechanisms involved in the influence of emotion on perception and working memory (WM), using modified 0-back and 2-back tasks, respectively. First, results showed that attentional focus modulated the impact of emotion on perception. Specifically, emotion facilitated perceptual task...
