Competing Sound Sources Reveal Spatial Effects in Cortical Processing
Why is spatial tuning in auditory cortex weak, even though location is important to object recognition in natural settings? This question continues to vex neuroscientists focused on linking physiological results to auditory perception. Here we show that the spatial locations of simultaneous, competing sound sources dramatically influence how well neural spike trains recorded from the zebra finc...
متن کاملCortical processing of dynamic sound envelope transitions.
Slow envelope fluctuations in the range of 2-20 Hz provide important segmental cues for processing communication sounds. For a successful segmentation, a neural processor must capture envelope features associated with the rise and fall of signal energy, a process that is often challenged by the interference of background noise. This study investigated the neural representations of slowly varyin...
متن کاملSpatial interactions reveal inhibitory cortical networks in human amblyopia
Humans with amblyopia have a well-documented loss of sensitivity for first-order, or luminance defined, visual information. Recent studies show that they also display a specific loss of sensitivity for second-order, or contrast defined, visual information; a type of image structure encoded by neurons found predominantly in visual area A18/V2. In the present study, we investigate whether amblyop...
متن کاملEffects of recurrent acute otitis media on cortical speech-sound processing in 2-year old children.
OBJECTIVES To investigate at the age of 2 years the effects of childhood recurrent acute otitis media (RAOM) on central auditory processing by using cortical event-related potentials elicited by syllable stimuli. DESIGN During a 1-year period, 22- to 26-month-old children fulfilling the criteria for tympanostomy tube insertion in Oulu University Hospital, Oulu, Finland, were recruited to the ...
متن کاملSpatial Encoding and Decoding of Focused Virtual Sound Sources
Spatial encoding refers to the representation of a sound field which allows storage and transmission of the latter. In the Ambisonics context, sound fields can be spatially encoded when their spherical wave spectrum is bandlimited. The process of deriving appropriate loudspeaker driving signals in order to reproduce an encoded sound field is known as spatial decoding. Care has to be taken when ...
