Activity-dependent Modulation of Synaptic Transmission in the Intact Human Motor Cortex Revealed with Transcranial Magnetic Stimulation

Autor: G.P. Zanette, C. Bonato, Antonio Fiaschi, Paolo Maria Rossini

Publikováno v: Cerebral Cortex. 12:1057-1062

Activity-dependent modulation of cortical synaptic transmission is a fundamental mechanism involved in learning and memory storage. This modulation has been widely studied in in vitro brain slices and in vivo animal models. More recently, transcrania

Parkinson’s disease and lower limb somatosensory evoked potentials: Apomorphine-induced relief of the akinetic-rigid syndrome and vertex P37-N50 potentials

Autor: G.P. Zanette, Frediano Tezzon, D Idone, Michele Tinazzi, Antonio Fiaschi

Publikováno v: Journal of the Neurological Sciences. 164:163-171

We evaluated brainstem P30, vertex-central P37-N50 and contralateral frontal N37 somatosensory evoked potentials (SEPs) from the tibial nerve in 14 patients affected by Parkinson’s disease (PD) with akinetic-rigid syndrome. In seven patients SEPs w

Effects of voluntary contraction on tibial nerve somatosensory evoked potentials Gating of specific cortical responses

Publikováno v: Neurology. 50:1655-1661

We evaluated vertex-parietal P37, N50, and contralateral N37 somatosensory evoked potentials (SEPs) to posterior tibial nerve stimulation during weak (20 to 30%) and strong (80 to 90%) ipsilateral gastrocnemius-soleus contraction. The results were co

Selective gating of lower limb cortical somatosensory evoked potentials (SEPs) during passive and active foot movements

Autor: F La Porta, Alberto Polo, Michele Tinazzi, G.P. Zanette, Antonio Fiaschi, D. Volpato, François Mauguière

Publikováno v: Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section. 104:312-321

We evaluated subcortical and cortical somatosensory evoked potentials (SEPs) in response to posterior tibial nerve stimulation in 4 experimental conditions of foot movement and compared them with the baseline condition of full relaxation. The experim

Amplitude Changes of Tibial Nerve Cortical Somatosensory Evoked Potentials When the Ipsilateral or Contralateral Ear Is Used as Reference

Autor: C. Bonato, G.P. Zanette, Michele Tinazzi, François Mauguière, Antonio Fiaschi, Alberto Polo, Paolo Manganotti

Publikováno v: Journal of Clinical Neurophysiology. 14:217-225

We performed topographical mapping of somatosensory evoked potentials (SEPs) to the posterior tibial nerve using earlobe references both ipsilateral and contralateral to the stimulation side. The voltage of the frontal contralateral N37 and P50 compo

Effect of stimulus rate on the cortical posterior tibial nerve SEPs: a topographic study

Autor: Antonio Fiaschi, François Mauguière, G.P. Zanette, Michele Tinazzi

Publikováno v: Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section. 100:210-219

We performed topographical mapping of somatosensory evoked potentials (SEPs) in response to posterior tibial nerve stimulation delivered at 2, 5 and 7.5 Hz in 15 healthy subjects. P37 was significantly attenuated at 5 and 7.5 Hz and the N50 component

Subcortical P30 potential following tibial nerve stimulation: Detection and normative data

Autor: Antonio Fiaschi, François Mauguière, Alberto Polo, C. Bonato, Paolo Manganotti, Michele Tinazzi, G.P. Zanette

Publikováno v: The Italian Journal of Neurological Sciences. 16:623-628

Stimulation of the tibial nerve evokes a P30 far-field potential over the scalp which, like the median nerve P14, probably originates in the vicinity of the cervico-medullary junction. Unlike the P14 potential, P30 recording has not been systematical
