Using high-resolution 7-T fMRI we have investigated the influence of positional information on sound object representations by comparing activation patterns to environmental sounds lateralised to the right ...

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. ...

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. ...
