The present research examines the effect of spatial (object-centered) attentional constraints on pattern recognition. Four normal subjects and two right-hemisphere-damaged patients with left visual neglect participated in the study. Small, letterlike, prelearned patterns served as stimuli. Short exposure time prevented overt scanpaths during stimulus(More)
Schizophrenic patients living in high contact with relatives having high expressed emotion (EE) were recruited for a trial of social interventions. The patients were maintained on neuroleptic medication, while their families were randomly assigned to education plus family therapy or education plus a relatives group. Eleven out of 12 families accepted family(More)
This paper outlines the evolution of ideas on the topic of alcoholic hallucinosis. From 1847 to 1987 numerous descriptive case-histories appeared in the literature. Analysis of these demonstrates that there were some phenomenological features of the illness about which authors were agreed. These were the acute onset of the illness, the predominance of(More)
Carpal tunnel syndrome (CTS) is associated with sensory and/or motor dysfunction of the hand's fingers. The syndrome is caused by a continuous or intermittent pressure on the median nerve (NM) at the patient's wrist. 82 patients suffering from recent CTS symptoms, and 24 matched asymptomatic controls were tested. In the present study we examined five(More)
BACKGROUND AND OBJECTIVE Megalencephaly (MEG) or enlarged brain occurs as a mild familial variant with normal brain structure, but otherwise is an uncommon human brain malformation that may be associated with significant developmental and neurological problems. It has been classified into anatomic and metabolic subtypes. The clinical findings associated(More)
The results are reported of a two-year follow-up of a trial of family sessions in the home (including patients) (12 families) versus a relatives' group (excluding patients) (11 families). Subjects were patients with schizophrenia living in high face-to-face contact with high-EE relatives. Patients were maintained on neuroleptic drugs for two years where(More)
"Cognitive" auditory event-related potentials (ERPs) were mapped to examine the putative conscious responsiveness of eight patients in a postcoma unawareness (PCU) state and of eight matched normal controls. A "passive P3" paradigm was used to evaluate waves N2, P3, and Slow Waves of the ERPs. Results showed that the signal/noise ratio of the patients'(More)
Natural vocalizations and their artificial counterparts were found to be equally effective in evoking responses in auditory cortex units of awake squirrel monkeys. Neural responsiveness was presumably based primarily on the sensitivity of the units to acoustic transients embedded in the stimuli. For the left hemisphere, a significantly higher percentage of(More)
Responsiveness of auditory cortex (AC) units of awake squirrel monkeys to a natural sequence of species-specific calls was not significantly different from their responsiveness to a reverse playback of the sequence. No dependency was noted between the percentage of responding units and the average intensity of sounds, their spectral content or their order(More)
