There has been persistent uncertainty as to whether lesions of the cerebellum are associated with clinically significant disturbances of behavior and cognition. To address this question, 20 patients with diseases confined to the cerebellum were studied prospectively over a 7-year period and the nature and severity of the changes in neurological and mental(More)
A central aspect of the cerebellar cognitive affective syndrome is the dysregulation of affect that occurs when lesions involve the 'limbic cerebellum' (vermis and fastigial nucleus). In this case series we describe neuropsychiatric disturbances in adults and children with congenital lesions including cerebellar agenesis, dysplasia, and hypoplasia, and(More)
Five aphasic subjects, who demonstrated agrammatic speech, and eight control subjects were presented with a sentence-picture matching task in which the factors of syntactic complexity, semantic reversibility, and sentence plausibility were independently varied. A subset of the sentences was patterned after that presented by A. Caramazza and E. Zurif (1976,(More)
This article concerns how the orientations of objects are represented in the human brain. We propose a coordinate-system hypothesis of orientation representation (COR) and show that the hypothesis provides an explicit basis for interpreting orientation errors. Next, we report results from three studies of individuals with developmental deficits in the(More)
INTRODUCTION With the recent publication of new criteria for the diagnosis of preclinical Alzheimer's disease (AD), there is a need for neuropsychological tools that take premorbid functioning into account in order to detect subtle cognitive decline. Using demographic adjustments is one method for increasing the sensitivity of commonly used measures. We(More)
We argue on the basis of recent experimental results that modular principles of universal grammar (UG) play a continuous role in the first language acquisition of control. Our results involve both comprehension and production data from 108 3- to 8-year old children who are acquiring English. The results provide evidence against the hypothesis that there is(More)
This paper demonstrates templated self-assemblysbased on capillary forcessof millimeter-scale poly-(dimethylsiloxane) plates suspended at the water-perfluorodecalin interface. The system described abstracts the concept of " templating " from molecular templating and uses it to design millimeter-scale aggregates that self-assemble in ordered structures. This(More)
Emotion attribution (EA) from faces is key to social cognition, and deficits in perception of emotions from faces underlie neuropsychiatric disorders in which cerebellar pathology is reported. Here, we test the hypothesis that the cerebellum contributes to social cognition through EA from faces. We examined 57 patients with cerebellar disorders and 57(More)
Only 30% of all breast cancer can be explained by known risk factors. Increases in breast cancer incidence rates in Hawaii over the past few decades cannot be attributed solely to improvements in screening and detection. Avoidable environmental factors may contribute to a proportion of the unexplained cases. Emerging evidence on endocrine disruption(More)
Cerebellar lesions can cause motor deficits and/or the cerebellar cognitive affective syndrome (CCAS; Schmahmann's syndrome). We used voxel-based lesion-symptom mapping to test the hypothesis that the cerebellar motor syndrome results from anterior lobe damage whereas lesions in the posterolateral cerebellum produce the CCAS. Eighteen patients with isolated(More)
