2、many,一、問題提出(,Objectives,),1,、,Alcohol-dependent patients often show various comorbid psychiatric symptoms.However,,,there is hardly any study considering the influence of these symptoms on cognitive processes,。,酒精依賴患者經(jīng)常會(huì)出現(xiàn)各種伴發(fā)精神疾病癥狀。但是,目前幾乎沒有任何研究來考慮這些癥狀對(duì)認(rèn)知功能的影響,。,直接說明自己研究主題,因?yàn)闆]人研究,。,2,、,There is som
3、e evidence that alcoholism may be associated with a range of cognitive and deficient behavioral control,。,目前已經(jīng)存在一些證據(jù)表明酗酒和一定范圍的認(rèn)知和行為控制缺陷有關(guān),。,但是還是存在一些相關(guān)研究表明我研究的問題還是存在的,3,、,No consensus exists about how different cognitive dimensions might be affected and whether there is a general decline in cognitive
4、 functioning or circumscribed impairments,。,關(guān)于不同的維度的認(rèn)知可能會(huì)受到影響,這一點(diǎn)并未達(dá)成一致。是否是認(rèn)知功能的普通降低或者說是限制性的損傷,。,有很多認(rèn)知功能,他們具體情況到底怎么樣還不明確,所以我要探討,4,、,Some studies,suggested that abilities which are mainly associated with right hemispheric functions are primarily affected in patients with alcohol use disorder,有些研究表明認(rèn)知
5、能力的損傷和右半球功能受到主要影響,對(duì)于酒精使用障。,表明自己為什么要用,FMRI,5,、,The go/nogo paradigmhas been widely used to show the neural correlates of response activation and inhibition and to assess impulsivity and control processes in healthy subjects,as well as several clinical groups,go/nogo,范式被廣泛的用于顯示健康者的反應(yīng)活動(dòng)和抑制的神經(jīng)關(guān)系,和用于評(píng)估沖動(dòng)
6、性和控制加工。也同樣用于一些臨床群體,。,我要用的范式是有效的,。,6,、,In contrast to event-related potentials functional MRI of the blood oxygenation level-dependent(BOLD)response measures hemodynamic changes in the brain associated with cognitive processes with a high-spatial resolution.,相比,ERP,,依賴血氧水平測(cè)量和認(rèn)識(shí)加工相關(guān)的大腦血氧變化的,FMRI,具有更高的
7、空間分辨率,。,為什么要用,FMRI,7,、,Epidemiological studies revealed that anxiety frequently co-occurs with alcohol use disorder,。,流行病學(xué)研究表明焦慮頻率和酒精使用障礙存在關(guān)系,。,表明我要研究的一個(gè)問題,。,二、研究假設(shè)(,Research hypothesis,),The purpose of the present study was to examine the neural correlates of behavioral inhibition in patients suffe
8、ring from alcohol disorder and in healthy controls,and to determine the influence of anxiety on these processes,當(dāng)前研究的目的是為了檢驗(yàn)酒精障礙和健康控制組的行為抑制的神經(jīng)關(guān)聯(lián)問題和探究焦慮對(duì)這些加工的影響。,We assumed that patients suffering from alcohol disorder would show reduced nogo-P3 amplitudes and smaller inhibition-related BOLD response
9、s compared to healthy subjects.However,in alcohol-dependent patients with high-trait anxiety neural responses were expected to be more distinct,。,研究假設(shè):,(,1,)酒精障礙患者和健康控制組相比表現(xiàn)出,nogo-P3,波幅減少和更小的抑制相關(guān)的,BOLD,反應(yīng)。,(,2,)高特質(zhì)焦慮的酒精依賴患者的神經(jīng)反應(yīng)存在更大差異,。,三、,Materials and methods,(材料和方法,),(一),Subjects,(被試),Sixteen det
