We assessed the impact of total and partial sleep loss on neural correlates of fear conditioning and extinction learning and recall in healthy young adults. Methods Participants (56.3% female, age 24.8±3.4) were randomized to a night of normal sleep (NS, n=48), sleep restriction (SR, n=53), or sleep deprivation (SD, n=53). All completed fear conditioning and… Continue reading Partial and Total #Sleep Deprivation Interferes with Neural Correlates of Consolidation of #Fear Extinction #Memory

The effects of acute #work #stress and appraisal on psychobiological stress responses in a group office environment
The high prevalence of office stress and its detrimental health consequences are of concern to individuals, employers and society at large. Laboratory studies investigating office stress have mostly relied on data from participants that were tested individually on abstract tasks. In this study, we examined the effect of psychosocial office stress and work interruptions on… Continue reading The effects of acute #work #stress and appraisal on psychobiological stress responses in a group office environment
Effects of #Psilocybin-Assisted Therapy on Major #Depressive Disorder
Major depressive disorder (MDD) is a substantial public health burden, but current treatments have limited effectiveness and adherence. Recent evidence suggests that 1 or 2 administrations of psilocybin with psychological support produces antidepressant effects in patients with cancer and in those with treatment-resistant depression.. ..Two psilocybin sessions (session 1: 20 mg/70 kg; session 2: 30… Continue reading Effects of #Psilocybin-Assisted Therapy on Major #Depressive Disorder
Losing Control: #Sleep Deprivation Impairs the Suppression of Unwanted #Thoughts

People vary widely in their talents at suppressing such memory intrusions; however, the factors that govern suppression ability are poorly understood. We tested the hypothesis that successful memory control requires sleep. Following overnight sleep or total sleep deprivation, participants attempted to suppress intrusions of emotionally… Continue reading Losing Control: #Sleep Deprivation Impairs the Suppression of Unwanted #Thoughts
Mortality risk of #antipsychotic augmentation for adult depression
Randomized controlled trials have demonstrated increased all-cause mortality in elderly patients with dementia treated with newer antipsychotics. It is unknown whether this risk generalizes to non-elderly adults using newer antipsychotics as augmentation treatment for depression.. ..Non-elderly adults (25–64 years) diagnosed with depression who after ≥3 months of antidepressant monotherapy initiated either augmentation with a newer… Continue reading Mortality risk of #antipsychotic augmentation for adult depression
What is the best way of delivering virtual #nature for improving mood?: An experimental comparison of high definition TV, 360º video, and computer generated virtual reality
Exposure to ‘real’ nature can increase positive affect and decrease negative affect, but direct access is not always possible, e.g. for people in health/care settings who often experience chronic boredom. In these settings ‘virtual’ forms of nature may also have mood-related benefits (e.g. reducing boredom) but it has been difficult to separate effects of nature… Continue reading What is the best way of delivering virtual #nature for improving mood?: An experimental comparison of high definition TV, 360º video, and computer generated virtual reality
Cognitive Factors Associated with Frequency of #Eating Out and Eating Takeout among Latinas
Higher frequency of eating outside the home can be an unhealthy behavior that may contribute to higher rates of obesity among Latinas, a disproportionately affected group. There is a growing need to understand potentially modifiable factors (eg, dispositional mindfulness, self-efficacy, nutrition knowledge) associated with higher frequency of eating outside the home in this population. This… Continue reading Cognitive Factors Associated with Frequency of #Eating Out and Eating Takeout among Latinas
