“…Previous studies have indicated that the right frontal lobe plays an important role in sustaining attention [33]. Sleepiness during the blood drawing procedure after night duty correlated negatively with the right prefrontal activity, suggesting right prefrontal involvement in attention and in working memory, which is defined as the temporary maintenance and manipulation of information necessary for performance [34].…”

Background: Overwork, fatigue, and sleep deprivation due to night duty are likely to be detrimental to the performance of medical residents and can consequently affect patient safety. Objective: The aim of this study was to determine the possibility of deterioration of cerebral function of sleep-deprived, fatigued residents using neuroimaging techniques. Design: Six medical residents were instructed to draw blood from artificial vessels installed on the arm of a normal cooperator. Blood was drawn at a similar time of the day, before and after night duty. To assess sleep conditions during night duty, the participants wore actigraphy units throughout the period of night duty. Changes in cerebral hemodynamics, during the course of drawing blood, were measured using a wearable optical topography system. Results: The visual analogue scale scores after night duty correlated negatively with sleep efficiency during the night duty (ρ = −0.812, p = 0.050). The right prefrontal cortex activity was significantly decreased in the second trial after night duty compared with the first (p = 0.028). The extent of [oxy-Hb] decrease, indicating decreased activity, in the right dorsolateral prefrontal cortex correlated negatively with the Epworth sleepiness score after night duty (ρ = −0.841, p = 0.036). Conclusions: Sleep deprivation and fatigue after night duty, caused a decrease in the activity of the right dorsolateral prefrontal cortex of the residents, even with a relatively easy routine. This result implies that the brain activity of medical residents exposed to stress on night duty, although not substantially sleep-deprived, was impaired after the night duty, even though they apparently performed a simple medical technique appropriately. Reconsideration of the shift assignments of medical residents is strongly advised.

“…Lesions of the SPL do not lead to impairments in nonspatial selective attention tasks [Shapiro et al, 2002; Vandenberghe et al, 2001b]. By contrast, lesions of the IPL in patients who do not have neglect lead to impairments in tests that involve the counting of nonlateralized monotonous auditory tones and the detection of a visual target at the center of a screen or of tactile stimuli presented to either hand [Rueckert and Grafman, 1996, 1998]. This study provides direct electrophysiological evidence for different roles of the right SPL and IPL during spatial and nonspatial attention tasks.…”

Few studies have directly compared the neural correlates of spatial attention (i.e., attention to a particular location) and nonspatial attention (i.e., attention to a feature in the visual scene) using well‐controlled tasks. Here, we investigated the neural correlates of spatial and nonspatial attention in humans using intracranial electroencephalography. The topography and number of electrodes showing significant event‐related desynchronization (ERD) or event‐related synchronization (ERS) in different frequency bands were studied in 13 epileptic patients. Performance was not significantly different between the two conditions. In both conditions, ERD in the low‐frequency bands and ERS in the high‐frequency bands were present bilaterally in the parietal cortex (prominently on the right hemisphere) and frontal regions. In addition to these common changes, spatial attention involved right‐lateralized activity that was maximal in the right superior parietal lobule (SPL), whereas nonspatial attention involved wider brain networks including the bilateral parietal, frontal, and temporal regions, but still had maximal activity in the right parietal lobe. Within the parietal lobe, spatial attention involved ERD or ERS in the right SPL, whereas nonspatial attention involved ERD or ERS in the right inferior parietal lobule. These findings reveal that common as well as different brain networks are engaged in spatial and nonspatial attention.

“…Imaging studies have shown that a right-dominant network including the middle and inferior frontal gyri is linked to inhibitory control (Garavan et al, 1999;Aron et al, 2003) and to top-down control in a more general sense (Fassbender et al, 2006). Furthermore, several studies have associated insufficient functioning of the right hemisphere frontostriatal circuitry to inadequate response suppression in attention deficit hyperactivity disorder (Casey et al, 1997;Clark et al, 2007), and patient studies have linked right prefrontal lesions to deficits in sustained attention (Wilkins et al, 1987;Rueckert and Grafman, 1996). In the current study, further revealed that for both ROIs, mean signal changes were smaller during undistracted attention than during divided attention (p<0.001 in both cases).…”
