The animal circadian pacemaker is composed of two transcriptional feedback loops, which regulate electrical activity in circadian neurons. Surprisingly, a new study reports that electrical activity can reprogram circadian transcription, and identifies CREB proteins as candidates for this reprograming.

BACKGROUND Energy drink consumption has continued to gain in popularity since the 1997 debut of Red Bull, the current leader in the energy drink market. Although energy drinks are targeted to young adult consumers, there has been little research regarding energy drink consumption patterns among college students in the United States. The purpose of this study was to determine energy drink consum...

One of the most frequent kind of typographic errors specific to Spanish is connected with accentuation, namely, with omission of an obligatory stress mark or insertion of a superfluous one. If such an error transforms one word to another existing one, the latter cannot be detected by usual spell-checkers, since some context analysis is necessary. A simple procedure is proposed for this task. It...

______________________________________________________ Speech Prosody of Dialectal French: Data and Hypotheses This paper contrasts the prosody of 6 varieties of French spoken in three different areas: France (Paris and Lyon), Belgium (Tournai and Liège), and Switzerland (Geneva and Neuchâtel). The objective is to address whether some prosodic criteria can help to classify distinct dialectal va...

Voice quality shifts have been shown to be associated with the realisation of accent, focus and deaccentuation. Mostly, accented and focally accented syllables are reported to exhibit a tenser mode of phonation than the unaccented, but accentuation with a laxer/breathier quality is also reported. Possibly, the long-term voice quality of the speaker (or of the utterance) influences the voice qua...

The present study used EEG to investigate how and when top-down prediction interacts with bottom-up acoustic signals in temporally selective attention during speech comprehension. Mandarin Chinese spoken sentences were used as stimuli. We systematically manipulated the predictability and de/accentuation of the critical words in the sentence context. Meanwhile, a linguistic attention probe 'ba' ...

In this study, the relation between the timing of a rising or falling pitch movement and the syllable it accentuates is investigated. The five-syllable utterance /mamamamama/ was provided with a relatively fast rising or falling pitch movement. The timing of the movement was systematically varied and Dutch subjects were asked to indicate which syllable they perceived as accented. In order to fi...
