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...

Childhood's end: ADHD, autism and schizophrenia tied to stronger inhibitory interactions in adolescent prefrontal cortex

(Medical Xpress)—Key cognitive functions such as working memory (which combines temporary storage and manipulation of information) and executive function (a set of mental processes that helps connec...

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...

Neural mechanisms of dual-task interference and cognitive capacity limitation in the prefrontal cortex

Simultaneous performance of two tasks often leads to deficits in the component tasks, an effect thought to depend on the lateral prefrontal cortex (LPFC). Here, the authors recorded single-neuron acti...

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...

Prefrontal cortex volume reductions and tic inhibition are unrelated in uncomplicated GTS adults.

Tics in Gilles de la Tourette syndrome (GTS) are repetitive patterned movements, resembling spontaneous motor behaviour, but escaping voluntary control. Previous studies hypothesised relations between...

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...

Differential Patterns of Prefrontal MEG Activation during Verbal & Visual Encoding and Retrieval.

The spatiotemporal profile of activation of the prefrontal cortex in verbal and non-verbal recognition memory was examined using magnetoencephalography (MEG). Sixteen neurologically healthy right-hand...

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...
