In the primate brain, sensory information is processed along two partially segregated cortical streams: the ventral stream, mainly coding for objects' shape and identity, and the dorsal stream, mainly coding for objects' quantitative information (including size, number, and spatial position). Neurophysiological measures indicate that such functional segregation is present early on in infancy, a...
This classic phenomenon, in which our brain analyzes a scene by perceptually organizing sensory data to form auditory objects (or auditory streams), is often referred to as the “Cocktail Party Effect” (Cherry, 1953). Many cues have been identified that influence perceptual organization, but only little is known about the actual brain mechanisms underlying this phenomenon. In this proposed topic...
Background & Objectives: One of the major questions in epidemiological and social science researches is studying the relationship of the living place with social and health outcomes. In this study, we measured segregation indices for a number of important socioeconomic indices using the 2006 Iranian census data to find out whether residential segregation is correlated with the available differe...
A sequence of sounds may be heard as coming from a single source (called fusion or coherence) or from two or more sources (called fission or stream segregation). Each perceived source is called a 'stream'. When the differences between successive sounds are very large, fission nearly always occurs, whereas when the differences are very small, fusion nearly always occurs. When the differences are...
Neural correlates of auditory stream segregation: An analysis of onset- and change-related responses
In many natural listening situations, meaningful sounds (e.g., speech) fluctuate in slow rhythms among other sounds. When a slow rhythmic auditory stream is selectively attended, endogenous delta (1‒4 Hz) oscillations in auditory cortex may shift their timing so that higher-excitability neuronal phases become aligned with salient events in that stream [1, 2]. As a consequence of this stream-bra...
