Cortical Representation of Natural Complex Sounds: Effects of Acoustic Features and Auditory Object Category

A. M. Leaver, J. P. Rauschecker
2010 Journal of Neuroscience  
Our results support a hierarchical organization of the anteroventral auditory-processing stream, with the most anterior regions representing the complete acoustic signature of auditory objects.  ...  Although specialized voice and speech-sound regions have been proposed, it is unclear how other types of complex natural sounds are processed within this object-processing pathway.  ...  HNR is calculated in a single time window as follows: HNR ϭ 10*log 10 (rЈ͑t max ͒/͑1 Ϫ rЈ͑t max ͒͒), where rЈ(t max ) is the strength of the strongest periodic component and (1 Ϫ rЈ(t max )) represents  ...

Category Training Induces Cross-modal Object Representations in the Adult Human Brain

Marieke van der Linden, Miranda van Turennout, Guillén Fernández
2011 Journal of Cognitive Neuroscience  
■ The formation of cross-modal object representations was investigated using a novel paradigm that was previously successful in establishing unimodal visual category learning in monkeys and humans.  ...  Stimulus blocks consisted of bird sounds only, bird pictures only, matching pictures and sounds (cross-modal congruent), and mismatching pictures and sounds (cross-modal incongru-ent). fMRI data showed  ...  Acknowledgments This research was supported by a grant from the Netherlands Organisation for Scientific Research (NWO 400-03-338).

2015 Cerebral Cortex  
They also reveal a hierarchical system of abstracted sensorymotor representations incorporating a major division between object interaction and object perception processes.  ...  With a multivariate fMRI design, we examined activation associated with 5 sensory-motor attributes-color, shape, visual motion, sound, and manipulation-for 900 words.  ...  Thus, the pMTG appears to be a sensory integration area where auditory and visual information are combined into bimodal representations of object motion.  ...

Distributed Neural Representations of Phonological Features during Speech Perception

J. S. Arsenault, B. R. Buchsbaum
2015 Journal of Neuroscience  
A fundamental goal of the human auditory system is to map complex acoustic signals onto stable internal representations of the basic sound patterns of speech.  ...  Although the neural structures underlying phonemic representations have been well studied, there is considerable debate regarding frontal-motor cortical contributions to speech as well as the extent of  ...  Discussion The objective of the current study was to investigate both local and distributed neural codes associated with phonological feature representations during speech perception.  ...
