Amyotrophic lateral sclerosis (ALS) is a progressive degenerative disease affecting upper and lower motor neurons. Symptom onset may occur in the muscles of the limbs (spinal onset) or those of the head and neck (bulbar onset). Bulbar involvement is particularly important in ALS as it is associated with increased morbidity and mortality. The purpose of this(More)
Short latency somatosensory evoked potentials (SSEPs) elicited by median nerve stimulation were monitored in 14 adult patients undergoing cardiac surgery under cardiopulmonary bypass and induced hypothermia. SSEPs were recorded at 1-2 degrees C steps as the body temperature was lowered from 37 degrees C to 20 degrees C to determine temperature-dependent(More)
Ten left hemisphere and 10 right hemisphere CVA patients were required to monitor for the target phoneme /b/ in a series of monosyllabic words, and a target timbre in a series of eight different timbres. Left hemisphere damaged aphasic patients were more accurate for target timbres over phonemes; the reverse pattern was found in the nonaphasic right(More)
The history of aphasia is usually taken to begin with Broca's (1861a,b) discovery of the correlation of aphemia with damage to the posterior inferior portion of the frontal lobes and the subsequent relation to left hemisphere. That there were prior, even biblical, references to aphasia is not in dispute, nor that, according to Benton and Joynt (1960),(More)
Mind transforms the continuance of physical space-time into moments (the absolute Now) and blends these moments into an apparent continuity through an overlapping of unfolding capsules. The flow of psychological time is an illusion based on the rapid replacement of these capsules. Each mind computes the measure of time passing and duration from the decay of(More)
This study examines the effect of different behavioral conditions on patterns of correlation between regional cerebral metabolic rates for glucose. Cerebral glucose metabolism was determined with positron emission tomography and (11C)-deoxyglucose in 29 normal subjects between the ages of 23 and 55. Seventeen subjects were studied in an unstimulated(More)
In a number of studies that have examined the gestural disturbance in aphasia and the utility of gestural interventions in aphasia therapy, a variable degree of facilitation of verbalization during gestural activity has been reported. The present study examined the effect of different unilateral gestural movements on simultaneous oral-verbal expression,(More)
