Musical training predicts cerebello-hippocampal coupling during music listening.
2018
Cerebello-hippocampal interactions occur during accurate spatiotemporal prediction of movements. In the context of music listening, differences in cerebello-hippocampal functional connectivity may result from differences in predictive listening accuracy. Using functional MRI, we studied differences in this network between 18 musicians and 18 nonmusicians while they listened to music. Musicians possess a predictive listening advantage over nonmusicians, facilitated by strengthened coupling between produced and heard sounds through lifelong musical experience. Thus, we hypothesized that musicians would exhibit greater functional connectivity than nonmusicians as a marker of accurate online pr…
Effect of Corticosteroids on Facial Function after Cerebellopontine Angle Tumor Removal: A Double-Blind Study versus Placebo
2015
The aim of this study was to assess the effect of corticosteroids administered intra- and postoperatively on the occurrence of facial palsy after a cerebellopontine angle (CPA) tumor resection, and to investigate pre- and intraoperative prognostic factors. A multicenter, prospective, randomized, double-blind and versus-placebo study was conducted between 2006 and 2010. Three hundred and ten patients operated on for a CPA tumor (96% vestibular schwannomas, 4% miscellaneous) were included by five participating centers. The population was stratified into patients with small (≤15 mm CPA on axial MRI views) and large tumors. In each group, patients were randomized to receive corticosteroid (1 mg…
Magnetic Resonance Imaging Surveillance for Vestibular Schwannoma After Microsurgical Resection Using a Retrosigmoid Transmeatal Approach.
2020
BACKGROUND Vestibular schwannoma (VS) is a benign, usually slow-growing tumor. The drawback of radical microsurgical VS resection is the increased likelihood of neurologic injury, forcing surgeons to leave a tumor remnant in some cases. We evaluated the prognostic value of magnetic resonance imaging (MRI) enhancement patterns to determine the risk of tumor regrowth. METHODS This clinical study included 30 patients (20 women and 10 men) with VS who underwent surgery via a retrosigmoid transmeatal approach. The extent of resection was assessed by MRI 6 months after surgery. Two subtypes of intracanalicular linear enhancement were defined: linear enhancement of the walls of the internal audito…
Radiosurgery as Treatment for Acoustic Neuroma. Ten Years’ Experience
2013
The acoustic neuroma is a benign tumour that usually affects the vestibular portion of the vestibulocochlear nerve. It represents 8% of all intracranial tumours and 80% of those arising at the cerebellopontine angle. There are 3 treatment options: microsurgery (the technique of choice), radiosurgery and observation. The objective of the study was to evaluate the results and side effects obtained using radiosurgery as treatment for acoustic neuroma.We performed a review of all patients treated with radiosurgery (Gamma Knife and linear accelerator) at doses of 1200-1300 cGy for unilateral acoustic neuroma in our hospital from January 1999 until January 2010. In all patients we evaluated the o…
The internal auditory artery: (embryology, anatomy, angiography, pathology).
1975
A review of the literature on the embryology, anatomy and angiography of the internal auditory artery has shown that there may be considerable variation as to the origin and number of internal auditory arteries. The present study, based on serial magnification angiographies of the internal auditory artery, has demonstrated 7 variants of the origin of this artery although in 45.4% of cases the internal auditory artery arose from the anterior inferior cerebellar artery. For the diagnosis of pathological processes in the cerebellopontine angle (tumors, sudden deafness, vascular abnormalities) magnification angiography is of special importance. Acoustic neurinomas in particular can be diagnosed…
Bello e Idea nell’estetica del Seicento
2007
The Beautiful and The Idea in 17th-Century Aesthetics In his renowned lecture on the Idea, which he delivered at the Academy of Saint Luke in 1664, Giovan Pietro Bellori asserts the superiority of ideal beauty against the slavish imitation of reality and the unbridled freedom of the imagination. However, an equally important, albeit lesser known, contributor to the formulation of this classicist aesthetic theory is Giovan Battista Agucchi, author of a Treatise on Painting that appeared in fragmentary form in 1646. In this work, Agucchi identifes beauty as the truest and highest aim of painting; he attributes to the artist the power to contemplate the Idea, and confers a profound cognitive v…
Electrical resistivity and induced polarization tomographies to test the efficiency and safety of the new landfill of Bellolampo (Palermo, Italy)
2016
A geophysical study by means of electrical resistivity and induced polarization tomographies was carried out in the landfill site of Bellolampo (Palermo, Italy) to check the integrity of the landfill liner and to detect possible leachate plumes. Preliminarily, synthetic tests were performed, simulating acquisition data along profiles placed above resistivity distribution, suitable to represent landfills protected with an high-density polyethylene (HDPE) liner at the bottom or with possible leachate plumes. Optimized array data sets for parallel measurements have been tested in order to assess the resolution and the effectiveness of tomographic images, comparing inversions with and without t…

Architetture rupestri a Caltabellotta
2020
Questo saggio descrivere i caratteri tipologici, le evoluzioni nel tempo e le connotazioni costruttive dell'architettura rupestre a Caltabellotta (AG). L’Italia rupestre, nella sua totalità, può – e non a torto - essere considerata un plusvalore se non ancora del tutto da scoprire, sicuramente da valorizzare e re-interpretare nel progetto di architettura e fruizione dei beni culturali e paesaggistici; non a caso, sovente le aree rupestri rappresentano un sistema attrattivo oggetto di tutela, inserito in piani paesistici e protetto da un vincolo di riserva naturale in ambito regionale, o ancora inserito in istituiti o istituendi distretti turistici. Il saggio ha analizzato cavità artificiali…
