SINCLAIR, k%J.JAM J. Role of the pharyngeal pbxus in initiation of swallowing. Am. J. Physiol. 221(5) : 1260-1263. 1971.-In preparation for stimulation studies, 22 cats were electrolytically decerebrated. The intact cephalic branch of the pharyngeal branch of the vagus nerve (Za) was electrically stimulated to determine its role in the initiation of the swallowing reflex. Comparative data were ...

Background and Aim: Human brain research in recent years has demonstrated the existence of mirror neurons in Brodmann areas (BA) 44, 6, and BA40. However, there has been almost no previous research on swallowing and mirror neurons. We have investigated the activity of mirror neurons during swallowingrelated visual stimulation. Subjects and Methods: Subjects were 15 healthy individuals (6 male, ...

PURPOSE To perform an integrative review of studies on liquid sequential swallowing, by characterizing the methodology of the studies and the most important findings in young and elderly adults. RESEARCH STRATEGY Review of the literature written in English and Portuguese on PubMed, LILACS, SciELO and MEDLINE databases, within the past twenty years, available fully, using the following uniterm...

Research exists that evaluates the mechanics of swallowing respiratory coordination in healthy children and adults as well and individuals with swallowing impairment. The research program summarized in this article represents a systematic examination of swallowing respiratory coordination across the lifespan as a means of behaviorally investigating mechanisms of cortical modulation. Using time-...

Stimulation of water receptors in the laryngopharynx (LP) with water facilitates voluntary swallowing in humans. Based on measures of swallowing intervals (SIs) in repetitive swallowing, we investigated characteristics of laryngopharyngeal water receptors in humans. Healthy adult volunteers were instructed to perform repetitive swallowing as quickly as possible during infusion of a solution int...

[Purpose] The purpose of this study was to investigate the effect of self-exercise on oropharyngeal swallowing function in patients with dysphagia. [Subjects and Methods] Nine patients with dysphagia after stroke were recruited. Self-exercise including effortful swallowing, tongue strengthening, and shaker exercise was performed 5 times a week for 4 weeks. Swallowing function was evaluated usin...

Lateral lemniscus, a relay nucleus of auditory sensation, is involved in the control of phonatory movements such as human speech and vocalization of animals. The present study was designed to test whether neurons in the lateral lemniscus contributed to the control of swallowing, one of non-phonic oro-pharyngolaryngeal movements. In acutely decerebrated cats (n=15), swallowing was induced by ele...

OBJECTIVE To investigate whether patterns of dysphagia and swallowing laterality differ according to the location of brain lesions in patients with stroke. METHODS Patients with stroke >20 years of age were enrolled in this study. A videofluoroscopic swallowing study (VFSS) including the anterior-posterior view was used to assess swallowing. Patterns of swallowing were classified into three t...

BACKGROUND Swallowing impairment is a common complication in various geriatric and neurodegenerative diseases. Swallowing kinematic analysis is essential to quantitatively evaluate the swallowing motion of the oropharyngeal structures. This study aims to develop a novel swallowing kinematic analysis software, called spatio-temporal analyzer for motion and physiologic study (STAMPS), and verify ...
