Attentional bias modification is associated with fMRI response toward negative stimuli in individuals with residual depression: a randomized controlled trial
(2019-08)BACKGROUND:Attentional bias modification (ABM) may lead to more adaptive emotion perception and emotion regulation. Understanding the neural basis of these effects may lead to greater precision for the development of future ... -
Cognition in Mood Disorders
(2020-01)Mood disorders are common, complex, and one of the main causes of morbidity worldwide (1). There has been an increasing recognition that cognitive dysfunction is a central aspect of most mood disorders, as well as being ... -
Cognitive neuropsychological theory of antidepressant action: a modern-day approach to depression and its treatment
(2020-01)Depression is a leading cause of disability worldwide and improving its treatment is a core research priority for future programmes. A change in the view of psychological and biological processes, from seeing them as ... -
A continuum hypothesis of psychotomimetic rapid antidepressants
(2021-05)Ketamine, classical psychedelics and sleep deprivation are associated with rapid effects on depression. Interestingly, these interventions also have common psychotomimetic actions, mirroring aspects of psychosis such as ... -
A Dissociation of the Acute Effects of Bupropion on Positive Emotional Processing and Reward Processing in Healthy Volunteers
(2018-10)Background: Previous research indicates that antidepressants can restore the balance between negative and positive emotional processing early in treatment, indicating a role of this effect in later mood improvement. However, ... -
Does repeatedly viewing overweight versus underweight images change perception of and satisfaction with own body size?
(2020-04)Body dissatisfaction is associated with subsequent eating disorders and weight gain. One-off exposure to bodies of different sizes changes perception of others' bodies, and perception of and satisfaction with own body size. ... -
Effect of acute citalopram on self-referential emotional processing and social cognition in healthy volunteers
(2020-10)Background Depression is characterised by negative views of the self. Antidepressant treatment may remediate negative self-schema through increasing processing of positive information about the self. Changes in affective ... -
Effect of Prefrontal Cortex Stimulation on Regulation of Amygdala Response to Threat in Individuals With Trait Anxiety A Randomized Clinical Trial
(2019-01)Importance Transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (DLPFC) is under clinical investigation as a treatment for major depressive disorder. However, the mechanisms of action are ... -
The effect of sertraline on emotional processing: secondary analyses of the PANDA randomised controlled trial
(2021-01)Background. According to the cognitive neuropsychological model, antidepressants reduce symptoms of depression and anxiety by increasing positive relative to negative information processing. Most studies of whether ... -
Effect of the NMDA receptor partial agonist, d-cycloserine, on emotional processing and autobiographical memory
(2020-04)Background: Studies suggest that d-cycloserine (DCS) may have antidepressant potential through its interaction with the glycine site of the N-Methyl-D-aspartate receptor (NMDAR); however clinical evidence of DCS’s efficacy ... -
An Experimental Medicine Investigation of the Effects of Subacute Pramipexole Treatment on Emotional Information Processing in Healthy Volunteers
(2021-08)Treatment with the dopamine D2/D3 receptor agonist pramipexole has demonstrated promising clinical effects in patients with depression. However, the mechanisms through which pramipexole might alleviate depressive symptoms ... -
An Experimental Medicine Investigation of the Effects of Subacute Pramipexole Treatment on Emotional Information Processing in Healthy Volunteers
(2021-08)Treatment with the dopamine D2/D3 receptor agonist pramipexole has demonstrated promising clinical effects in patients with depression. However, the mechanisms through which pramipexole might alleviate depressive symptoms ... -
Glucocorticoid ultradian rhythmicity differentially regulates mood and resting state networks in the human brain: A randomised controlled clinical trial
(2021-02)Adrenal glucocorticoid secretion into the systematic circulation is characterised by a complex rhythm, composed of the diurnal variation, formed by changes in pulse amplitude of an underlying ultradian rhythm of short ... -
How representative are neuroimaging samples? Large-scale evidence for trait anxiety differences between MRI and behaviour-only research participants.
(2020-04)Over the past three decades, MRI has become a key tool to study how cognitive processes are implemented in the human brain. However, the question of whether participants recruited into MRI studies differ from participants ... -
How women with and without eating disorders perceive their own and others’ bodies: a case-control study
(University of Bristol, 2020-03)Background: Body dissatisfaction is a key part of the psychopathology of eating disorders, but there is a lack of consensus as to whether the dissatisfaction arises from misperception of body size, and if such misperception ... -
The knowns and unknowns of SSRI treatment in young people with depression and anxiety: efficacy, predictors, and mechanisms of action
(2021-08)The use of SSRIs for the treatment of depression and anxiety in young people is increasing. However, the effects of SSRIs in adolescence, a time when there are substantial changes in neural, cognitive, and social functioning, ... -
Lithium modulates striatal reward anticipation and prediction error coding in healthy volunteers
(2020-10)Lithium is one of the most effective mood-stabilizing medications in bipolar disorder. This study was designed to test whether lithium administration may stabilize mood via effects on reward processing. It was hypothesized ... -
Neural effects of a single dose of fluoxetine on resting-state functional connectivity in adolescent depression
(2020-11)Fluoxetine is commonly prescribed in adolescent depression, but the neural mechanisms underlying its action remain poorly understood. Here, we used resting-state functional magnetic resonance imaging to investigate the ... -
Neurocognitive processes in d-cycloserine augmented single-session exposure therapy for anxiety: A randomized placebo-controlled trial
(2020-06)Drugs targeting N-methyl-d-aspartate (NMDA) receptors and the ability to learn new associations have been proposed as adjunct treatments to boost the success of exposure therapy for anxiety disorders. However, the effects ... -
The Oxford study of Calcium channel Antagonism, Cognition, Mood instability and Sleep (OxCaMS): study protocol for a randomised controlled, experimental medicine study
(2019-02)Background: The discovery that voltage-gated calcium channel genes such as CACNA1C are part of the aetiology of psychiatric disorders has rekindled interest in the therapeutic potential of L-type calcium channel (LTCC) ...
