Children with complex communication needs often have multiple disabilities including visual impairments that impact their ability to interact with aided augmentative and alternative communication (AAC) systems. Just as the field benefited from a consideration of visual cognitive neuroscience in construction of visual displays, an exploration of…

Speech recognition is an active process that involves some form of predictive coding. This statement is relatively uncontroversial. What is less clear is the source of the prediction. The dual-stream model of speech processing suggests that there are two possible sources of predictive coding in speech perception: the motor speech system and the…

Our understanding of the neurobiological basis for human speech production and perception has benefited from insights from psychology, neuropsychology and neurology. In this overview, I outline some of the ways that functional imaging has added to this knowledge and argue that, as a neuroanatomical tool, functional imaging has led to some…

The brain mechanisms of hearing include large regions of the anterior temporal, prefrontal, and inferior parietal cortex, and an extensive network of descending connections between the cortex and sub-cortical components of what is presently known as the auditory system. One important function of these additional ("top-down") mechanisms for hearing…

The principles of Hungarian music educator Zoltan Kodaly can be particularly useful not only in teaching children how to read music notation but also in creating curiosity and enjoyment for reading music. Many of Kodaly's ideas pertaining to music literacy have been echoed by educators such as Jerome Bruner and Edwin Gordon, as well as current…

It is well documented that aging adversely affects the ability to perceive time-varying acoustic cues. Here we review how physiological measures are being used to explore the effects of aging (and concomitant hearing loss) on the neural representation of temporal cues. Also addressed are the implications of current research findings on the…

"Science Briefs" summarize the findings and implications of a recent study in basic science or clinical research. This Brief reports on the study "Perinatal Exposure to a Noncoplanar Bichlorinated Biphenol Alters Tonotopy, Receptive Fields and Plasticity in the Auditory Cortex" (T. Kenet; R. C. Froemke; C. E. Schreiner; I. N. Pessah; and M. M.…

Speech production involves the integration of auditory, somatosensory, and motor information in the brain. This article describes a model of speech motor control in which a feedforward control system, involving premotor and primary motor cortex and the cerebellum, works in concert with auditory and somatosensory feedback control systems that…

In the paper, we discuss the importance of network interactions between brain regions in mediating performance of sensorimotor and cognitive tasks, including those associated with language processing. Functional neuroimaging, especially PET and fMRI, provide data that are obtained essentially simultaneously from much of the brain, and thus are…

We report the case of an immigrant who suffered from death threats and head trauma while a prisoner of war in Kuwait. Two months later, he began to hear conversations that had taken place previously. These perceptions occurred spontaneously or were induced by the patient's effortful concentration. The single photon emission computerized tomography…

We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…
