Smooth-pursuit eye movements are voluntary responses to small slow-moving objects in the fronto-parallel plane. They evolved in primates, who possess high-acuity foveae, to ensure clear vision about the moving target. The primate frontal cortex contains two smooth-pursuit related areas; the caudal part of the frontal eye fields (FEF) and the supplementary eye fields (SEF). Both areas receive ve...

Many neurons in the supplementary eye field (SEF) of the macaque monkey fire at different rates before eye movements to the right or the left end of a horizontal bar regardless of the bar's location in the visual field. We refer to such neurons as carrying object-centered directional signals. The aim of the present study was to throw light on the nature of object-centered direction selectivity ...

Subepithelial fibrosis (SEF) and the transdifferentiation of keratocytes into fibroblasts or myofibroblasts (Fbs/MFbs) have been detected in the cornea of individuals with bullous keratopathy. We examined the anterior cornea of bullous keratopathy patients for such changes after Descemet's stripping automated endothelial keratoplasty (DSAEK). Twenty-two individuals who underwent unilateral DSAE...

OBJECTIVE To evaluate the effects of prone and supine sleeping positions on electrocortical activity during active (AS) and quiet (QS) sleep in low birthweight infants. DESIGN Randomised/crossover study. SETTING Infant Physiology Laboratory at Children's Hospital of New York. PATIENTS Sixty three healthy, growing, low birthweight (birth weight 795-1600 g) infants, 26-37 weeks gestational ...

The role of the supplementary eye fields (SEF) during smooth pursuit was investigated with electrical microstimulation. We found that stimulation in the SEF increased the acceleration and velocity of the eyes in the direction of target motion during smooth pursuit initiation but not during sustained pursuit. The increase in eye velocity during initiation will be referred to as pursuit facilitat...

Abstract Wildlife feeding activities are growing as a trend in recent years, with wild ruminants (e.g. deer urban parks) receiving an increasingly unnatural diet result of public attention. The effects on the gastrointestinal tract have been established context animal agriculture, highly modified diets driving morphological changes rumen papillae. However, these dietary not widely explored that...
