Multisyllabic nonsense-word repetition tasks have been used to provide evidence on the phonological processing operations of children with language impairment, independent of their lexical knowledge (Gathercole & Baddeley, 1990; Kamhi, Catts, Mauer, Apel, & Gentry, 1988). However, recent evidence (Gathercole, Willis, Emslie, & Baddeley, 1991) and(More)
The anatomical basis of memory disorder related to lesions of the diencephalon is a controversial matter. A study of a patient who developed severe amnesia in association with bilateral metastatic tumour invasion of the medial and posterior thalamus is reported. The findings in this case have led to further discussion of this unsettled issue.
Human sleep is characterized by episodes of immobility and by major body movements occurring in phase with the EEG sleep cycle. Using time-lapse videotape recording and electrophysiological monitoring, we studied the sleep of four normal subjects to determine the relationship of the movements to sleep cycle phase and the consistency of the power of the(More)
Three patients had amnesia and confusion as presenting features of thalamic hemorrhage. They had a relatively benign clinical appearance and lacked characteristics of the syndrome usually associated with thalamic hemorrhage. We reviewed hypotheses regarding a mechanism for the amnesic syndrome and concluded that lesions involving the medial thalamic nucleus(More)
STUDY OBJECTIVES Assessment of sleep and its substages in mice currently requires implantation of chronic electrodes for measurement of electroencephalogram (EEG) and electromyogram (EMG). This is not ideal for high-throughput screening. To address this deficiency, we present a novel method based on digital video analysis. This methodology extends previous(More)

We describe a patient with documented Lyme disease whose major complaint was increasing abdominal distention. Electrophysiologic studies demonstrated denervation of the lower thoracic paraspinal muscles and the rectus abdominis. Expanding abdominal girth can be an unusual manifestation of the polyradiculoneuropathy associated with Lyme disease.
