The dorsal bank of the primate superior temporal sulcus (STS) is a polysensory area with rich connections to unimodal sensory association cortices. These include auditory projections that process complex acoustic information, including conspecific vocalizations. We investigated whether an extensive left posterior temporal (Wernicke's area) lesion, which included destruction of early auditory co...

OBJECTIVE To assess whether there is an association of level of fetal cocaine exposure to developmental precursors of speech-language skills at 1 year of age, after controlling for confounding factors. DESIGN In a prospective, longitudinal, quasi-experimental, matched cohort design, 3 cocaine exposure groups were defined by maternal self-report and infant meconium assay: nonexposure (n = 131)...

The role of superior temporal cortex in speech comprehension is well established, but the complete network of regions involved in understanding language in ecologically valid contexts is less clearly understood. In a functional magnetic resonance imaging (fMRI) study, we presented 24 subjects with auditory or audiovisual narratives, and used model-free intersubject correlational analyses to rev...

This paper presents three studies which examine the susceptibility of sentence comprehension to intrusion by extra-sentential probe words in two on-line dual-task techniques commonly used to study sentence processing: the cross-modal lexical priming paradigm and the unimodal all-visual lexical priming paradigm. It provides both a general review and a direct empirical examination of the effects ...

Speech comprehension relies on temporal cues contained in the speech envelope, and the auditory cortex has been implicated as playing a critical role in encoding this temporal information. We investigated auditory cortical responses to speech stimuli in subjects undergoing invasive electrophysiological monitoring for pharmacologically refractory epilepsy. Recordings were made from multicontact ...

Cochlear implants are neuroprostheses designed to restore speech perception in case of profound bilateral hearing loss. As speech is fundamentally an audiovisual percept, a deficit in processing auditory information might lead to changes in audiovisual integration of speech comprehension. Using vowel-consonant-vowel stimuli under unimodal, audiovisual congruent and audiovisual incongruent (McGu...

The brain's analyses of speech and music share a range of neural resources and mechanisms. Music displays a temporal structure of complexity similar to that of speech, unfolds over comparable timescales, and elicits cognitive demands in tasks involving comprehension and attention. During speech processing, synchronized neural activity of the cerebral cortex in the delta and theta frequency band...

The location of brain regions essential for auditory language comprehension is an important consideration in the planning of neurosurgical procedures that involve resections within the dominant temporal lobe. Language testing during intraoperative and extraoperative cortical stimulation has been the primary method for localizing these regions; however, noninvasive alternatives using functional ...

Aphasia is a systemic disturbance of speech, revealing in the complete loss or partial loss of speech and local lesion caused by one or more of the speech areas in the brain. In most cases, aphasia occurs in adults, however, it is also possible in children, if the brain injury occurred after it had been formed, at least partially. The term ‘aphasia’ is derived from the Greek ‘fasio’ (say) and t...

The distinction between input and intake was first proposed by Corder (1967). Whether or not target language input becomes intake is determined by various factors, one of which is perceptual saliency. The language phenomenon called reduced forms, which is observed in informal spoken languages, decreases perceptual saliency, and is thus believed to influence the input-intake process in SLA. Henr...
