Exploiting development to evaluate auditory encoding of amplitude modulation.
During development, detection for many percepts matures gradually. This provides a natural system in which to investigate the neural mechanisms underlying performance differences: those aspects of neural activity that mature in conjunction with behavioral performance are more likely to subserve detection. In principle, the limitations on performance could be attributable to either immature sens...
متن کاملConcurrent Encoding of Frequency and Amplitude Modulation in Human Auditory Cortex: An Encoding Transition
Complex natural sounds (e.g., animal vocalizations or speech) can be characterized by specific spectrotemporal patterns whose components change in both frequency (frequency modulation, FM) and amplitude (amplitude modulation, AM). The neural coding of AM and FM has been widely studied in humans and animals, but typically with either pure AM or pure FM stimuli. The neural mechanisms employed to ...

متن کاملModeling auditory processing of amplitude modulation
In this thesis a new modeling approach is developed which is able to predict human performance in a variety of experimental conditions related to modulation detection and modulation masking. Envelope uctuations are analyzed with a modulation lterbank. The parameters of the lterbank were adjusted to allow the model to account for modulation detection and modulation masking data with narrowband c...
