We study partially hyperbolic diffeomorphisms satisfying a trapping property which makes them look as if they were Anosov at large scale. We show that, as expected, they share several properties with Anosov diffeomorphisms. We construct an expansive quotient of the dynamics and study some dynamical consequences related to this quotient.

Most naming treatments in aphasia either assume a phonological or semantic emphasis or a combination thereof. However, it is unclear whether semantic or phonological treatments recruit the same or different cortical areas in chronic aphasia. Employing three persons with aphasia, two of whom were non-fluent, the present study compared changes in neural recruitment associated with phonologic and ...

PURPOSE The Kentucky Aphasia Test (KAT) is an objective measure of language functioning for persons with aphasia. This article describes materials, administration, and scoring of the KAT; presents the rationale for development of test items; reports information from a pilot study; and discusses the role of the KAT in aphasia assessment. METHOD The KAT has 3 parallel test batteries, KAT-1, KAT...

Little is known about the processing of non-verbal sounds in the primary progressive aphasias. Here, we investigated the processing of complex non-verbal sounds in detail, in a consecutive series of 20 patients with primary progressive aphasia [12 with progressive non-fluent aphasia; eight with semantic dementia]. We designed a novel experimental neuropsychological battery to probe complex soun...

a bearing on graphic aphasia, or, as it is more correctly designated, agraphia. Agraphia has been known for many years to be a frequent symptom in all the types of aphasia, but the question as to whether there was a type of aphasia which could be strictly called graphic aphasia without any other lesion is one that has been much discussed in recent years. In order to bring the subject properly b...

Aphasia centers are in an excellent position to contribute to the broad definition of health by the World Health Organization: the ability to live life to its full potential. An expansion of this definition by the World Health Organization International Classification of Functioning, Disability and Health (ICF) forms the basis for a user-friendly and ICF-compatible framework for planning interv...

Aphasia as a multifaceted language disorder associated with the complicated links between language and brain has been and is of interest and significance to the stream of research in different disciplines including neurolinguistics, psycholinguistics, cognitive studies and language acquisition. Along with explorations into the manifestations of aphasia in monolingual speakers, bilingual aphasia...

An extensive search of aphasia-treatment literature yielded 55 reports of clinical outcomes satisfying the essential criteria for inclusion in a meta-analysis. The results confirmed those of an earlier meta-analysis in demonstrating the utility of aphasia treatments, generally considered, for bringing about desirable clinical outcomes. Beyond the general case, the new findings address clinical ...
