Our sensorimotor experience unfolds in sequences over time. We hypothesize that the processing of movement sequences with and without a temporal pause will recruit distinct but cooperating neural processes, including cortico-striatal and cortico-cerebellar networks. We thus, compare neural activity during sequence learning in the presence and absence of this pause. Young volunteer participants ...

Theories of language production need to account for how speakers produce prosodic structure. Very few models have addressed the role of prosodic phrasing in speech planning, and little experimental work examining this question has been conducted so far. Four studies designed to investigate the effect of phrase length and prosodic phrasing on speech planning are presented. The first experiment e...

The work reported in this paper is part of a project that aims at describing the role of prosody in conveying discourse structure in European Portuguese. We conducted an empirical study to investigate whether the organization of discourse could be reflected by the occurrence of pauses. In order to achieve that, we started by asking sixteen subjects to annotate two texts using two discourse segm...

Eleven patients with tachycardia-dependent, bradycardia-dependent, or "pseudobradycardia-dependent" bundle branch block (BBB) alternans were studied. This classification is based on the following criteria: 1) When alternans is initiated by a sudden acceleration in ventricular rate, or it appears with aberration of the second beat after a pause, the alternans is tachycardia-dependent and results...

Pauses play important roles for the intelligibility and naturalness of speech. Their occurrence and duration in text reading are influenced by syntactic structures of the text as well as by physiological constraints of respiration on the part of the speaker. In contrast to sentenceand paragraph-final pauses, sentence-medial pauses are influenced by a number of factors. Analysis of Japanese news...

Rats were required to complete varying numbers of licks (FR), ranging from 10 to 300, in order to free an activity wheel for predetermined times (CT) ranging from 2 to 20 sec. The reinforcement of drinking by running was shown both by an increased frequency of licking, and by changes in length of the burst of licking relative to operant-level burst length. In log-log coordinates, instrumental l...
