Somaesthetic evoked potentials (SEPs) have been recorded on the parietal scalp of 375 normal and awake children to brief electrical stimulation (0.5 msec) applied to the contralateral median nerve at the wrist. Each SEP was obtained by summation of the responses to 150 stimuli delivered at a frequency of 1/sec. The population studied has been divided in(More)
Bibliometric indicators are increasingly used to fund and evaluate scientific research. Since the number of authors in a paper and the number of has increased it is difficult to determine the individual contribution of authors. Suggested approaches include the study of author position or the corresponding author. Our findings show that the corresponding(More)
An electromyographic study was performed in 50 cases of severe infantile spinal muscular atrophy (type I). 164 muscles and 93 nerves (ulnar and posterior tibialis) were tested. The thresholds of stimulation of the motor nerves were increased. Motor action potential was absent in 30% of the investigated nerves, motor nerve conduction velocity was slow in(More)
Alterations of the functional properties of the cerebellar parallel fibers have been investigated in scrapie mice by recording the compound action potential elicited by the superficial stimulation of the cerebellum. As soon as the 12th week following intracerebral inoculation, i.e. during the silent incubation period, there is a clear decrease of the(More)
The results of somesthetic evoked response (SER) and electroencephalogram (EEG) records in 43 children with hemiplegic cerebral palsy have been compared. In all children there was a positive correlation between the SER changes and the affected side of the body. In 12 children the SER of the "damaged" hemisphere disappeared; in 31 children it was less than(More)
Ontogenic evolution of behavioural and electrophysiological responses to the serotonergic agents, quipazine and harmaline, was studied in the maturing rabbit in normal and pretreated conditions. As regards behavioural effects, tremor induced by quipazine was present from the first postnatal day and was antagonized by methysergide, but not by(More)
