Cinema in realtà virtuale e in realtà aumentata sono esperienze cinematiche espanse che si indirizzano a un vero e proprio cinema neurale
L'intelligenza. Teorie e modelli, III edizione
2011
In una rassegna ampia e dettagliata, le più significative teorie dell'intelligenza, così come si sono sviluppate dalla metà dell'Ottocento fino ad oggi, dai contributi teorici dei positivisti inglesi alle ricerche più recenti, legate allo sviluppo dei modelli computazionali e simulativi.
Come è piccolo il mondo in rete: una ipotesi small-world sulla topologia di Facebook
2010
Il contributo descrive una prima ipotesi di modellizzazione della struttura comunicativa e sociale di Facebook, effettuata assimilando tale network sociale a una rete con topologia small-world di tipo scale free. La topologia small-world presenta una struttura analoga alle strutture dei sistemi biologici e sociali, alle reti di associazioni tra idee e concetti e ad alcuni network artificiali (quali internet e le rotte aeree), e consente di spiegare l’evoluzione di questi sistemi in termini di aggiunta, rimozione e modifica di parti. Per testare la nostra ipotesi abbiamo analizzato i profili di 1001 utenti Facebook selezionati su base volontaria (F = 70%; M = 30%; età media = 25.5; DS = 7.0;…
LE DISRAFIE SPINALI CISTICHE: casistica e attuali orientamenti terapeutici in età neonatale
1990
Gli Autori riportano la loro esperienza sul trattamento delle disrafie spinali cistiche in età neonatale e, dopo una revisione della letteratura, ne sottolineano gli aspetti deontologici, clinici e terapeutici
Association between sensorineural hearing loss and sleep-disordered breathing: Literature review
2015
The cochlea is especially sensitive to circulatory alterations because it is supplied by a single terminal artery and lacks adequate collateral blood supply. To examine the putative association between Sensorineural Hearing Loss (SNHL) and Sleep Disordered Breathing (SDB) through the literature review is very interesting. In fact these medical disorders usually are associated to cerebral circulatory alterations resulting in hypoxia, acute hemodynamic change, and decreased cerebral blood flow, because the Sleep Disorder Breathing (SDB), for example OSAHS (Obstructive Sleep Apnea Hypopnea Syndrome), is characterized by periodic hyposia/reoxygenation. These noxious stimuli can, in turn, activa…
Sudden sensorineural hearing loss
2019
Sudden sensorineural hearing loss (SSNHL), is an important otological disorder that affects up to 5-20 in 100,000 people. It is characterized by a rapid loss of the hearing, usually unilateral, with a sensorineural hearing loss greater than 30 dB over three consecutive frequencies, in less than 72 hours and can be associated with tinnitus and vertigo. It is a real sensorineural emergency that can become a permanent handicap if not adequately treated. Because of patients recovering rapidly or seeking no medical attention, the true figure might be higher, even if delaying SHL diagnosis and treatment may decrease the effectiveness of treatment. Sudden Hearing Loss can occur at any age but usua…
Screening e post-screening (Audiologia essenziale)
2014
Newborn hearing screening is a type of screening test for the early detection of hearing loss. It can recognize with good accuracy newborns affected by hearing impairment allowing an early diagnosis and intervention and avoiding cognitive and linguistic deficits [1,2,3,4,5,6]. The incidence of bilateral sensorineural hearing loss (SNHL) in Sicily is 2.35 cases per 1000 newborns; this value increases to 2.95 if we consider also unilateral SNHL [2,3] and to 10 cases per 1000 births among infants at risk [7,8,9]. A correct newborn hearing screening programme is based on different protocols depending on the presence/absence of audiologic risk factors: • Newborns without risk factors: [1,2,3] In…
TINNITUS PATIENTS: ETIOLOGIC, AUDIOLOGIC AND PSYCHOLOGICAL PROFILE
2013
Tinnitus represents one of the most frequent symptoms observed in the general population in association with different pathologies, although often its etiology remains unclear. Objective of this work is to evidence the main aspects concerning epidemiology, causes, audiological characteristics and psychological consequences of tinnitus.
Sensorineural hearing loss: Pathophysiology, diagnosis and treatment
2019
Hearing loss is one the commonest disabling diseases affecting populations of all ages worldwide. The impairment of hearing may be the cause of impaired language development in children, the cause of scholarly issues in adolescents, the cause of worsening of quality of life in the adults, and the cause of isolation of aged people. In this book, the authors present the hearing loss in all its facets, starting from the basis of pathophysiology and anatomy, passing through the clinical and instrumental diagnosis and, finally, describing the most important diseases causing hearing loss with reasonable treatment options. A section was dedicated to the imaging of the ear with about 100 original f…
