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...

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...

Exploring the brain: New findings explain how eyes link to prefrontal cortex

A research team has linked how our eyes actually see the world to neurons in the prefrontal cortex of the brain. The team studied saccadic eye movements -- those movements where the eye jumps from one...

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...

Shift workers: Evidence for sleep-inducing and alertness drugs is weak

Shift workers are taking drugs to help them stay awake or get to sleep despite weak evidence for their benefit, according to a new Cochrane review. The authors of the review found only small numbers o...

Blood donations could help reduce the risk of heart disease in shift workers

Austrian researchers have found that jetlag has severe effects on red blood cells, possibly explaining the high incidence of heart disease seen in shift workers. However, these effects can be counterb...

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-...

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...

Historical cohort study of shift work and blood pressure.

BackgroundIt has been suggested that shift work (SW) is associated with changes in blood pressure (BP). However, studies have reported contradictory results.AimsTo prospectively examine the associatio...

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...

Prefrontal cortical regulation of fear learning.

The prefrontal cortex regulates the expression of fear based on previously learned information. Recently, this brain area has emerged as being crucial in the initial formation of fear memories, provid...
