Variability of speech rhythm in synchronous speech
Speakers are able to speak in synchrony to another speaker or to a recording of another speaker. The present research studied whether and, if yes, speakers change their speech rhythm when synchronizing to another speaker. We developed a measure (SRratio) which monitors on a scale between 0 and 1 whether the durational characteristics of a speaker’s synchronous speech are closer to his/her own r...
متن کاملHippocampal Theta Modulation of Neocortical Spike Times and Gamma Rhythm: A Biophysical Model Study
The hippocampal theta and neocortical gamma rhythms are two prominent examples of oscillatory neuronal activity. The hippocampus has often been hypothesized to influence neocortical networks by its theta rhythm, and, recently, evidence for such a direct influence has been found. We examined a possible mechanism for this influence by means of a biophysical model study using conductance-based mod...
متن کاملStrength of Gamma Rhythm Depends on Normalization
Neuronal assemblies often exhibit stimulus-induced rhythmic activity in the gamma range (30-80 Hz), whose magnitude depends on the attentional load. This has led to the suggestion that gamma rhythms form dynamic communication channels across cortical areas processing the features of behaviorally relevant stimuli. Recently, attention has been linked to a normalization mechanism, in which the res...
متن کاملSynchronous Chaos and Broad Band Gamma Rhythm in a Minimal Multi-Layer Model of Primary Visual Cortex
Visually induced neuronal activity in V1 displays a marked gamma-band component which is modulated by stimulus properties. It has been argued that synchronized oscillations contribute to these gamma-band activity. However, analysis of Local Field Potentials (LFPs) across different experiments reveals considerable diversity in the degree of oscillatory behavior of this induced activity. Contrast...
متن کاملRhythm as entrainment: The case of synchronous speech
One view of rhythm, not conventionally adopted in speech research, is that it constitutes an affordance for movement. We test this view in an experimental situation in which speakers speak in synchrony with one another. After first establishing that speakers can synchronize with specific recordings, we present two experiments in which the information in the model speech is systematically reduce...
