Neural basis of speech perception.
The functional neuroanatomy of speech processing has been difficult to characterize. One major impediment to progress has been the failure to consider task effects when mapping speech-related processing systems. We summarize a dual-stream model of speech processing that addresses this situation. In this model, a ventral stream processes speech signals for comprehension, and a dorsal stream maps...
متن کاملNeural and behavioral mechanisms of olfactory perception.
Recent in vivo and in vitro studies have challenged existing models of olfactory processing in the vertebrate olfactory bulb and insect antennal lobe. Whereas lateral connectivity between olfactory glomeruli was previously thought to form a dense, topographically organized inhibitory surround, new evidence suggests that lateral connections may be sparse, nontopographic, and partly excitatory. O...
متن کاملChemistry of Odor Perception The Molecular Basis of Olfactory Chemoreception**
Chemoreception is the aptitude of living organisms to identify natural or synthetic chemical compounds in their environment and to evaluate their concentration. 2] In April 1970, the organic chemist Robert Luft was asked how volatile odorant molecules are perceived by the olfactory system. “Si vous r pondez ) cette question,” he replied, “le Prix Nobel est ) vous”. The 2004 Nobel Prize inMedici...
متن کاملThe neural basis of tactile motion perception.
The manipulation of objects commonly involves motion between object and skin. In this review, we discuss the neural basis of tactile motion perception and its similarities with its visual counterpart. First, much like in vision, the perception of tactile motion relies on the processing of spatiotemporal patterns of activation across populations of sensory receptors. Second, many neurons in prim...
متن کاملThe neural basis of object perception.
Humans can recognize an object within a fraction of a second, even if there are no clues about what kind of object it might be. Recent findings have identified functional properties of extrastriate regions in the ventral visual pathway that are involved in the representation and perception of objects and faces. The functional properties of these regions, and the correlation between the activati...
