The efficacy of stimulation patterns consisting of brief high frequency bursts repeated at various intervals to induce long-term potentiation (LTP) at synapses on apical and basal dendrites of CA1 hippocampal neurons was tested in vitro. Both apical and basal dendritic synapses exhibited maximal LTP after bursts repeated at 5-10 Hz, i.e. close to the(More)
Cervical artery dissection (CAD) represents an increasingly recognized cause of stroke and the most common cause of ischemic stroke in young adults. Many factors have been identified in association with CAD such as primary disease of arterial wall (fibrodysplasia) and other non-specific diseases related to CAD like Ehlers Danlos-syndrome IV, Marfan's(More)
OBJECTIVES The aims of this study were to analyse TBI rehabilitation in Italy, identifying the main factors conditioning motor and functional recovery and destination upon discharge of traumatic severe acquired brain injury (sABI) patients who had undergone intensive rehabilitative treatment. DESIGN An observational prospective study of 863 consecutive(More)
The effect of high frequency stimulation (HFS) of the primary vestibular afferents on field potentials recorded in the ipsilateral Medial Vestibular Nuclei (MVN) was studied. Our results show that potentiation and depression can be induced in different portions of MVN, which are distinguishable by their anatomical organization. HFS induces potentiation of(More)
In rat brainstem slices, we investigated the effects of low-frequency stimulation (LFS) of the primary vestibular afferents on the amplitude of the field potentials evoked in the medial vestibular nuclei (MVN). LFS induced long-term effects, the sign of which depended on whether the vestibular neurons were previously conditioned by HFS. In unconditioned(More)
As previously demonstrated, high frequency stimulation (HFS) of the primary vestibular afferents always induces a clear, long lasting depression of the polysynaptic (N2) component of the field potentials recorded in the dorsal portion of the medial vestibular nuclei (MVN). The induction of the HFS effect was mediated by the activation of glutamate NMDA(More)
OBJECTIVE To assess the impact on stroke outcome of statin use in the acute phase after IV thrombolysis. METHODS Multicenter study on prospectively collected data of 2,072 stroke patients treated with IV thrombolysis. Outcome measures of efficacy were neurologic improvement (NIH Stroke Scale [NIHSS] ≤ 4 points from baseline or NIHSS = 0) and major(More)
The possibility that N-methyl-D-aspartate (NMDA) receptor activation plays a role in inducing the vestibular compensation following hemilabyrinthectomy (HL) in guinea pigs, was verified by means of continuous intraventricular osmotic pumping of DL-2-Amino-5-phosphono-valeric acid (APV). Our results show that high doses (40 and 20 mM) of APV decrease both(More)
PURPOSE Back conditions are a group of impairments that induce limitation of activities and restriction of participation, in particular delaying the Return to work (RTW). The purpose of this review is to analyse the components involved in RTW. METHOD We have included the studies and reviews about the intervention, assessment tools, variables used to(More)
