We have previously demonstrated extensive activation in the dorsolateral temporal lobes associated with masking a speech target with a speech masker, consistent with the hypothesis that competition...

Speech perception is supported by both acoustic signal decomposition and semantic context. This study, using event-related fMRI, investigated the neural basis of this interaction with two speech...

AbstractPositron emission tomography was used to investigate two competing hypotheses about the role of the left inferior frontal gyrus (IFG) in word generation. One proposes a domain-specific...
CONFIGURATION INTERACTION IN MAGNESIUM, (2005)
Zero-order eigenfunctions and first-order energies are obtained in the hydrogenic Z-expansion scheme for magnesium-like systems. Full account is taken of configuration interaction arising in...

Positron emission tomography (PET) was used to investigate the neural basis of the comprehension of speech in unmodulated noise ("energetic" masking, dominated by effects at the auditory periphery),...
Monitoring and the controlled processing of meaning: distinct prefrontal systems (2004)
Distinct prefrontal regions are specialized for the controlled processing of semantic information. We have dissociated components of this system used in semantic decision-making across different...
Retrieving meaning after temporal lobe infarction: the role of the basal language area (2004)
During speech comprehension the auditory association cortex in the superior temporal cortex is involved in perceptual analysis of the speech signal, whereas the basal language area in the inferior...

The functional anatomy of single-word reading in patients with hemianopic and pure alexia (2001)
...
We investigated single-word reading in normal subjects and patients with alexia following a left occipital infarct, using PET. The most posterior brain region to show a lateralized response was at...
Impaired reading in patients with right hemianopia (2000)
...
A left occipital stroke may result in alexia for two reasons, which may coexist depending on the distribution of the lesion. A lesion of the left lateroventral prestriate cortex or its afferents...
