Using high-field (3 Tesla) functional magnetic resonance imaging (fMRI), we demonstrate that auditory and somatosensory inputs converge in a subregion of human auditory cortex along the superior temporal gyrus. Further, simultaneous stimulation in both sensory modalities resulted in activity exceeding that predicted by summing the responses to the unisensory inputs, thereby showing multisensory...

Pure word deafness is a disorder of auditory verbal comprehension without dysfunction of speaking, reading, or writing. This rare symptom arises from bilateral lesions in the temporal lobes or disconnection between the primary auditory cortex and Wernicke’s area. I present a right-handed 33-year-old woman who presented with pure word deafness and complex auditory hallucination with intermittent...

Accumulating evidence demonstrates that responses in auditory cortex to auditory consequences of self-generated actions are modified relative to the responses evoked by identical sounds generated by an external source. Such modifications have been suggested to occur through a corollary discharge sent from the motor system, although the exact neuroanatomical origin is unknown. Furthermore, since...

Auditory cortical columns have been studied for decades, but intracolumnar processing in auditory cortex is still poorly understood, relative to what is known about such processing in visual cortex and somatosensory cortex. While there are certainly striking similarities in cortical structure across the modalities, investigations of auditory cortex anatomy and synaptic physiology have also foun...

Despite numerous studies of auditory cortical processing in the ferret (Mustela putorius), very little is known about the connections between the different regions of the auditory cortex that have been characterized cytoarchitectonically and physiologically. We examined the distribution of retrograde and anterograde labeling after injecting tracers into one or more regions of ferret auditory co...

The human auditory cortex comprises multiple areas, largely distributed across the supratemporal plane, but the precise number and configuration of auditory areas and their functional significance have not yet been clearly established. In this paper, we discuss recent research concerning architectonic and functional organisation within the human auditory cortex, as well as architectonic and neu...
