“…It objectifies the perceptual abnormalities and functional and psychosocial consequences of sensory gating. SGI could confirm anomalies of sensory gating and perceptual inundation in schizophrenia (Micoulaud-Franchi and Vion-Dury, 2013;Micoulaud-Franchi et al, 2014;El-Kaim et al, 2015), attention-deficit hyperactivity disorder (ADHD) (Sable et al, 2012;Micoulaud-Franchi et al, 2014; and Tourette syndrome (Sutherland Owens et al, 2011).…”

Toward An Exploration of Habituating to Tinnitus: Perspectives on Sensory Gating

Some tinnitus participants habituate to their tinnitus, but some others do not and complain of its annoyance so much. It has been suggested that tinnitus is a habituation deficit. Habituation and the ability to ignore a sensory input depend on the normal function of filtering mechanism of sensory gating.The purpose of this study was to compare behavioral aspects of sensory gating in normal and tinnitus participants to search for the reason why some tinnitus participants habituate to their tinnitus but some others do not.This investigation was an observational case–control study.There were 60 tinnitus participants who were categorized into two tinnitus groups (30 compensated tinnitus participants and 30 decompensated tinnitus participants) based on the complaint of tinnitus annoyance, visual analog scale (VAS) for tinnitus loudness, annoyance, and awareness, scores on Tinnitus Questionnaire (TQ), and Tinnitus Handicap Inventory (THI). Also, there were 30 normal hearing participants without tinnitus as the normal control group.Sensory Gating Inventory (SGI), TQ, THI, and VAS was obtained from all participants. THI, TQ, VAS, and SGI total scores and their factors were compared among the groups. Correlations between SGI scores with THI, TQ, and VAS score were calculated.The results showed that SGI total score and the scores of its four factors were significantly higher in decompensated tinnitus participants compared with compensated tinnitus participants and normal controls. Also, there was a positive correlation between SGI perceptual modulation factor and TQ emotional distress factor and with the VAS for loudness in decompensated tinnitus group.These results suggested that tinnitus associated with behavioral aspects of sensory gating and decompensated tinnitus may be a result of deficient sensory gating.

“…This could be exacerbated by the high variety and intensity of auditory stimuli present in urban environments ( Gottschalk, 1972 , Landon et al, 2016 , Wright et al, 2014 ). Patients with schizophrenia appear to have increased responses to noises from urban environments compared to healthy controls ( Tregellas et al, 2009 , Tregellas et al, 2007 ) and have more difficulty integrating auditory stimuli into a single coherent understanding, particularly when stimuli include negative or frightening emotional valence ( El-Kaim et al, 2015 ). These stimuli in urban environments are less predictable and more intense than in rural environments and, over time, the cumulative impact of these stimuli appear to increase risk, potentially due to compensatory neural alterations ( Light and Braff, 2003 , McGhie and Chapman, 1961 , Nelson et al, 2014 , Postmes et al, 2014 ).…”

“…Some authors have reported higher sensibility to urban noise among patients suffering from schizophrenia (Tregellas et al, 2007;Tregellas, Ellis, Shatti, Du, & Rojas, 2009). Furthermore, a recent study (El-Kaim et al, 2015) using realistic immersive environmental auditory scenes, established that schizophrenia patients, shown to have a higher sensitivity to nonstationary sounds (i.e with high rate of impacted acoustic features), had greater difficulties in combining stimuli into coherent representation than subjects from a control group, especially when it comes to negative or frightening emotional valence of the stimulus. These elements suggest a possible role for acoustic stimulations in the emergence or the persistence of psychotic symptoms.…”

Background: A growing body of evidence suggests that urban living contributes to the development of psychosis. However, the mechanisms underlying this phenomenon remain unclear. This paper aims to explore the best available knowledge on the matter, identify research gaps and outline future prospects for research strategies. Method:A comprehensive literature survey on the main computerised medical research databases, with a time limit up to August 2017 on the issue of urbanicity and psychosis has been conducted. Results:The impact of urbanicity may result from a wide range of factors (from urban material features to stressful impact of social life) leading to "urban stress". The latter may link urban upbringing to the development of psychosis through overlapping neuro-and socio-developmental pathways, possibly unified by dopaminergic hyperactivity in mesocorticolimbic system. However, "urban stress" is poorly defined and research based on patients' experience of the urban environment is scarce. Conclusions: Despite accumulated data, the majority of studies conducted so far failed to explain how specific factors of urban environment combine in patients' daily life to create protective or disruptive milieus. This undermines the translation of a vast epidemiological knowledge into effective therapeutic and urbanistic developments. New studies on urbanicity should therefore be more interdisciplinary, This article is protected by copyright.
