We recorded event-related potentials to an acoustic "oddball" paradigm from 19 scalp derivations in five patients (three women and two men; age range, 44 to 56) who had global amnesia following encephalitis. CT and MRI showed severe bilateral lesions of anterior and midtemporal lobes. A P3 component, with a peak latency within the normal limits for(More)
We studied 10 patients with post-traumatic amnesia (PTA) and normal CTscans. P3 with an oddball paradigm, several neuropsychological tests and EEG were performed the day after the trauma and several times later until full recovery. In all patients, P3 latencies at admission were above normal limits (mean + 2 SDs) and decreased progressively during recovery(More)
Delayed P3 ERPs were recorded with an acoustic oddball paradigm in 5 patients affected by unilateral thalamic hemorrhage. P3 latencies in these 5 patients were above the normal mean latency of age-matched controls +2/+3 S.D.s. The P3 delay was persistent in serial follow-ups at 6 months from stroke. Normal P3 latencies were instead recorded in 4 patients(More)
The paper reports the results of recordings and maps of event-related potentials (ERPs) obtained in normal subjects. ERPs were recorded from 19 scalp electrode derivations using both visual and acoustic paradigms. In normal subjects, topographical distribution of all ERP components is described in detail. Our findings in normals suggest that the early(More)
24 juvenile strain 13 guinea pigs were sensitized with homologous spinal cord homogenate in complete Freund's adjuvant in order to obtain Experimental Allergic Encephalomyelitis (EAE) in the Chronic Relapsing (CR-EAE), Chronic Progressive (CP-EAE) and Acute (A-EAE) forms. Visual, Brain-Stem Acoustic, Somatosensory Evoked Potentials were recorded in these(More)
Event-related potentials (ERPs) to an odd-ball paradigm were recorded from 19 scalp derivations in a patient (47 years old, housewife) affected by complete amnestic syndrome following limbic encephalitis. CT scans and magnetic resonance imaging showed severe bilateral lesions of anterior, mid-temporal lobes and frontal lobes. A P3 component, with a peak(More)
This paper reports the results of recordings and maps of event-related potentials (ERPs) obtained in normal subjects, patients with Alzheimer's disease (AD), progressive supranuclear palsy, confusional states, and in subjects with homonymous hemianopsia. ERPs were recorded from 19 scalp electrode derivations using both visual and acoustic paradigms. In(More)
Visual evoked potentials (VEPs) to pattern reversal vertical bar stimuli of 3 different sizes (1, 2, 4 c/deg) were recorded from 19 scalp derivations in 50 controls. The stimuli were presented on a full-field (FF) screen of 24 degrees visual angle, and on left and right half-fields (HF) of 12 degrees radius. In 15 controls partial HF stimuli were presented(More)
Bit mapped color imaging of SEPs was recorded from 19 derivations in 11 healthy volunteers after electrical stimulation of the median nerve at the wrist, index finger digital nerve stimulation, and mechanical stimulation of the index fingertips by an electromechanically driven vibrating thin metallic plate. The latencies of SEP components increased for the(More)
Systemic administration of L-acetylcarnitine HCl (LAC) increases in human subjects the amplitude of visual evoked potentials (VEPs) obtained with patterned elements of 7.5 min of visual angle, of steady-state VEPs obtained with intermittent luminous stimulation, of EEG theta, alpha and beta bands. The latency of the "cognitive" P300 potential obtained with(More)
