The Edinger-Westphal nucleus (EWN) is a central preganglionic parasympathetic cell group that gives rise to cholinergic input to the ciliary ganglion, thereby regulating several neurovegetative ocular functions. Recently, the supposed presence of the neuropeptide urocortin (UCN) has been reported in EWN neurons in rodent brain. The purpose of the present study was to examine the distribution of...

The development of functional Ca(2+)-activated K(+) channels (K(Ca)) in chick ciliary ganglion (CG) neurons requires interactions with afferent preganglionic nerve terminals. Here we show that the essential preganglionic differentiation factor is an isoform of beta-neuregulin-1. beta-Neuregulin-1 transcripts are expressed in the midbrain preganglionic Edinger-Westphal nucleus at developmental s...

One hour of near work produced adaptive changes in the resting states of accommodation and binocular vergence, which may be responsible for different aspects of visual fatigue. Two groups of college students read from either hard copy or a video display terminal (VDT). Immediately before and after reading, the subjects' distance acuity, dark vergence, dark focus, and accommodative response accu...

Purpose These experiments were designed to reveal the location of the premotor neurons that have previously been designated physiologically as the midbrain near response cells controlling vergence, lens accommodation, and pupillary constriction in response to target distance. Methods To identify this population, the fixed N2c strain of rabies virus was injected into the ciliary body of seven ...

BACKGROUND Movement disorders in Huntington's disease are often medically refractive. The aim of the trial was assessment of procedure safety of deep brain stimulation, equality of internal- and external-pallidal stimulation and efficacy followed-up for 6 months in a prospective pilot trial. METHODS In a controlled double-blind phase six patients (four chorea-dominant, two Westphal-variant) w...

Nesfatin-1 is a recently identified satiety molecule detectable in neurons of the hypothalamus and nucleus of solitary tract (NTS). Immunohistochemical studies revealed nesfatin-1-immunoreactive (irNEF) cells in the Edinger-Westphal nucleus, dorsal motor nucleus of vagus, and caudal raphe nuclei of the rats, in addition to the hypothalamus and NTS reported in the initial study. Double-labeling ...

Heuristic search has been the mainstream approach in planning for more than a decade, with planners such as FF, FD, and LAMA being able to solve problems with hundreds of actions and variables in a few seconds (Hoffmann and Nebel 2001; Helmert 2006; Richter and Westphal 2010). The basic idea behind these planners is to search for plans using a search algorithm guided by heuristic estimators der...
