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 increase of co-authored papers is a recognized fact. At the same time the factors influencing this change is not well known. This article aims at studying the patterns of EU science co-authorships. We analyzed articles published in 18 EU countries and their intra-EU (within EU) and extra-EU (with partners outside EU) co-publication pattern in five(More)
Event-related potentials (ERPs) were recorded (01, 02, Fcz, Cpz leads) from 32 normal children aged from 6 to 8 years during a categorisation task performed with 4 types of stimuli that allowed for a holistic and/or an analytic development to modify information processing according to the child's age. Whatever age, derivation or stimulus, the individual(More)
