Original Source: Emergency medicine residents' use of psychostimulants and sedatives to aid in shift work.

OBJECTIVES: We evaluated the frequency that emergency medicine house staff report use of stimulants and sedatives to aid in shift work and circadian transitions. METHODS: We surveyed residents from 12 regional emergency medicine programs inviting them to complete a voluntary, anonymous electronic questionnaire regarding their use of stimulants and sedatives. RESULTS: Out of 485 eligible residents invited to participate in the survey, 226 responded (47% response frequency). The reported use of prescription s...

Prefrontal cortex: Dopamine double rules

Dopamine receptor subtypes 1 and 2 in the prefrontal cortex contribute to rule-based executive function via differential but complementary effects.

Damage to dorsolateral prefrontal cortex affects tradeoffs between honesty and self-interest

This study uses data from patients with damage to specific parts of the frontal cortex to provide causal evidence for the role of the dorsolateral prefrontal cortex in enabling honest behavior. Damag...

Epigenetic tie to neuropsychiatric disorders found

Dysfunction in dopamine signaling profoundly changes the activity level of about 2,000 genes in the brain's prefrontal cortex and may be an underlying cause of certain complex neuropsychiatric disorde...

Representation of aversive prediction errors in the human periaqueductal gray

This study uses fMRI in humans to find that prediction errors about pain are encoded in the periaqueductal gray. Modeling inter-area connectivity suggests that the ventromedial prefrontal cortex and t...

Association between exposure to rotating night shift versus day shift using levels of 6-sulfatoxymelatonin and cortisol and other sex hormones in women.

The present study aims to compare 6-sulfatoxymelatonin (aMT6s) secretion patterns and levels of cortisol and sex hormones (estradiol, progesterone, DHEA, DHEAS, and testosterone) among rotating night-...

Is the Prefrontal Cortex Especially Enlarged in the Human Brain Allometric Relations and Remapping Factors.

There has been no agreement as to whether the prefrontal cortex is especially enlarged in the human brain. To answer this question, we analyzed the only two datasets that provide information on total ...

Sleep loss, circadian mismatch, and abnormalities in reorienting of attention in night workers with shift work disorder.

Permanent night-shift workers may develop shift-work disorder (SWD). In the current study, we evaluated neurophysiological and behavioral indices of distractibility across times prior to the night shi...

Case fatality of myocardial infarction among shift workers.

Shift work has been associated with an excess risk of cardiovascular disease (CVD) and more specifically myocardial infarction (MI). The majority of the studies that found a positive association betwe...

Prefrontal Cortex Neurochemical Metabolite Levels in Major Depression and the Effects of Treatment: An HMRS Study.

Neuronal degeneration in the prefrontal cortex during depression results in altered production of neurochemical metabolites. The aim of the present study is to examine changes in neurochemical metabol...
