The frontal eye field (FEF) has long been regarded as a cortical area critically involved in the execution of voluntary saccadic eye movements. However, recent studies have suggested that the FEF may also play a role in orienting attention. To address this issue, we reversibly inactivated the FEF using multiple microinjections of muscimol, a GABAA agonist, in two macaque monkeys performing visu...

Imaging, lesion, and transcranial magnetic stimulation (TMS) studies have implicated a number of regions of the brain in searching for a target defined by a combination of attributes. The necessity of both frontal eye fields (FEF) and posterior parietal cortex (PPC) in task performance has been shown by the application of TMS over these regions. The effects of stimulation over these two areas h...

Saccadic eye movements can be elicited by more than one type of sensory stimulus. This implies substantial transformations of signals originating in different sense organs as they reach a common motor output pathway. In this study, we compared the prevalence and magnitude of auditory- and visually evoked activity in a structure implicated in oculomotor processing, the primate frontal eye fields...

introduction: renal failure affects the mechanical and the ventilatory function of the lungs. a few studies have evaluated the ventilatory and pulmonary function in dialysis patients. the present study aimed to compare pulmonary function test (pft) results in patients undergoing hemodialysis (hd) and peritoneal dialysis (pd). materials and methods: we conducted a cross-sectional study on 50  pa...

Transcranial magnetic stimulation (TMS) allows non-invasive perturbation of neural activity, induced by a rapidly changing magnetic field. Both single pulse and repetitive TMS (rTMS) have been shown to modulate behavioural output. Despite being considered an important methodology in cognitive neuroscience and as a potential treatment for neurological disorders, a precise understanding of the ef...

OBJECTIVE To establish reference values for pulmonary function in the Asian-Indian population living in the United States. DESIGN Five-year cross-sectional study of pulmonary function in healthy adult Asian Indians living in the United States, using American Thoracic Society guidelines for measuring pulmonary function. SETTING Measurement of pulmonary function in healthy nonsmoking Asian In...

Probiotics have been linked to a reduction in the incidence of necrotizing enterocolitis and late-onset sepsis in preterm infants. Recently, probiotics have also proved to reduce time to achieve full enteral feeding (FEF). However, the relationship between FEF achievement and type of feeding in infants treated with probiotics has not been explored yet. The aim of this systematic review and meta...

The dorsal and ventral parts of the lateral prefrontal cortex have been thought to play distinct roles in decision making. Although its dorsal part such as the frontal eye field (FEF) is shown to play roles in accumulation of sensory information during perceptual decision making, the role of the ventral prefrontal cortex (PFv) is not well-documented. Previous studies have suggested that the PFv...

The latency and variability of latency of single-unit responses to identical visual stimulation were measured in the frontal eye field (FEF), supplementary eye field (SEF), and anterior cingulate cortex (ACC) of macaque monkeys performing visually guided saccades. The mean visual response latency was significantly shorter in FEF (64 ms) than in SEF (81 ms) or ACC (100 ms), and latency values de...
