Recent studies done on healthy older individuals have demonstrated elevated taste thresholds for sweet, sour, and salty taste. At suprathreshold levels, such individuals have also shown less ability to discriminate between different intensities of the same tastant. This study was designed to provide information on swallow timing and muscle contraction(More)
Chicken embryos were treated with partially paralysing doses of d-tubocurarine (dtc) from embryonic (E) days 6 to 10. The pattern of innervation of the lateral gastrocnemius (GL) muscle was examined both morphologically and physiologically just before hatching on day E20 or E21. There was a 70% increase in number of surviving motor neurons in the lateral(More)
The elimination of the polyneuronal innervation was reinvestigated in normal rats from the tenth day after birth. The extent of polyneuronal innervation was measured by intracellular recordings in cut muscle fibre preparations. (Barstad 1962). This preparation has the advantage that it favours the recording of small signals. With this increased nerve(More)
Surface electromyography (EMG) has been used successfully in teaching patients swallow maneuvers in clinical settings. The present study aims to determine if surface EMG can reliably demonstrate differences in muscle activity between the normal swallow and the Mendelsohn maneuver and whether there is a close temporal relationship between submental muscles(More)
Morphological, ultrastructural and electrophysiological properties of endplates in the frog cutaneous pectoris muscle were monitored at various times after nerve crush. The lengths of regenerating terminals were measured in nitroblue tetrazolium-stained material. Quantal content and the frequency of spontaneous potentials were obtained from intracellular(More)
The properties of junctions formed de novo in ectopic regions of muscle were studied and compared to those of endplates reinnervated after nerve crush and to normals. The nerve to the frog cutaneous pectoris muscle was transposed and implanted onto an endplate-free (ectopic) region of that muscle, while the endplate-containing portion was excised. New(More)
