To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor control still remain open. One of them is the mechanism(s) by which neurotransmitters, such as dopamine, modulate speech and song production. In this review, we bring together the two fields of investigations of dopamine action on voice control in humans and songbirds, who share similar behavioral and neural mechanisms for speech and song production. While human studies investigating the role of dopamine in speech control are limited to reports in neurological patients, research on dopaminergic modulation of bird song control has recently expanded our views on how this system might be organized. We discuss the parallels between bird song and human speech from the perspective of dopaminergic control as well as outline important differences between these species. 相似文献

The personality trait Openness/Intellect reflects the tendency to be imaginative, curious, perceptive, artistic, and intellectual - all characteristics that involve cognitive exploration. Little is known about the biological basis of Openness/Intellect, but the trait has been linked to cognitive functions of prefrontal cortex, and the neurotransmitter dopamine plays a key role in motivation to explore. The hypothesis that dopamine is involved in Openness/Intellect was supported by examining its association with two genes that are central components of the prefrontal dopaminergic system. In two demographically different samples (children: N = 608; adults: N = 214), variation in the dopamine D4 receptor gene (DRD4) and the catechol-O-methyltransferase gene (COMT) predicted Openness/Intellect, as main effects in the child sample and as a gene-gene interaction in adults. 相似文献

There is a large gulf between what psychiatric services should (or could) provide and what they do in practice. This article sought to determine practice differences between the differing professions working in adult mental health services in terms of their family focused work. Three hundred and seven adult mental health professionals completed a cross‐sectional survey of family focused practices in adult mental health services. Findings highlight that social workers engaged in more family focused practice compared to psychiatric nurses, who performed consistently the lowest on direct family care, compared to both social workers and psychologists. Clear skill, knowledge, and confidence differences are indicated between the professions. The article concludes by offering direction for future profession education and training in family focused practices. 相似文献

In this paper the city of Copenhagen is used as a starting point to highlight some critical historical events, both concerning the exchange of ideas between the physicist Wolfgang Pauli and C.G. Jung and the history of psychotherapy in Scandinavia. Pauli's years in Copenhagen under the influence of Niels Bohr and his philosophy prepared him mentally to receiveC.G. Jung's ideas. The paper also recounts the one occasion that Jung was in Scandinavia, attending the 9th conference of the General Medical Society for Psychotherapy in Copenhagen, just before going to New York in 1937 to give his final seminars on Pauli's dreams. The reason for focusing on these particular events is that they also constitute part of the history of the reception of psychodynamic psychology in Sweden and Scandinavia. 相似文献

Perceived social support is a multifaceted construct conceptualized as one's cognitive appraisal as to the existence of a connection to others, based on trust, on whom one can rely on when necessary. The aim of this paper is to examine the psychometric properties of perceived social support, using the following scales: Social Support Questionnaire-Short Form (SSQ6) and Social Provisions Scale (SPS), on a sample of 855 first year university students – 575 females and 280 males – enrolled in 16 professional degrees at the University of Santiago de Compostela (Spain). The SSQ6 Scale assesses the dimensions of perceived support availability and satisfaction, whilst the SPS Scale assesses its social support functions. The factor analysis conducted confirms the SSQ6 Scale's two-dimensional model and the SPS Scale's six-factor structure. Internal consistency of both scales is satisfactory, as is the evidence of validity obtained from the correlations between the two scales and their subscales. The results reveal that the Spanish version of the SSQ6 and SPS scales are reliable and valid measurements for assessing perceived social support amongst university students. 相似文献

研究甲状腺癌组织中趋化因子4受体(CXCR4)和趋化因子7受体(CXCR7)的表达情况及临床病理意义。应用免疫组织化学PV-6000法及Westernblot法检测CXCR4与CXCR7在甲状腺癌中的表达。二者在甲状腺癌与甲状腺良性疾病组织的差异均具有统计学意义(P〈0.05),在甲状腺癌中表达仅与淋巴结转移有关(P〈0.05),CXCR4与CXCR7之间呈正相关。Westernblot结果提示二者在甲状腺癌中的表达率高于癌旁及甲状腺腺瘤。CXCR4和CXCR7的表达水平与淋巴结转移相关,可作为甲状腺癌预后的判断指标。 相似文献

研究术后镇痛对创伤患者围术期细胞因子IL 6、TNFα和胰岛素抵抗(IR)的影响.选取60例患者,随机分为两组,A组患者应用一次性术后镇痛泵,加入舒芬太尼2.5μg/kg+盐酸托烷司琼4mg,用生理盐水稀释至100ml,2ml/h持续注入.B组患者为术后根据临床需要临时给予杜冷丁每次50mg~100mg肌肉注射,每日不超过3次.发现两组患者术后镇痛效果比较,A组患者舒适程度要优于B组,随访患者无与药物相关的不良反应.术后两组患者血浆IL-6、TNF-α水平均开始升高,术后12h左右达峰值,24h后开始回落,但均明显高于术前.血糖和血胰岛素值也在术后升高,术后24h左右达峰值,之后逐渐回落.ISI在术后开始降低,术后24h降到最低,之后逐渐回升,但均低于术前,说明IL-6、TNF-α水平升高与创伤后胰岛素抵抗有相关性.A组患者术后12h、24h、36h、48h的血糖、血胰岛素、IL-6、TNF-α水平与B组比较明显降低,而且术后48h基本可以恢复术前水平.应用舒芬太尼术后镇痛可以通过抑制血浆中IL-6和TNF-α水平,从而抑制围术期胰岛素抵抗,降低应激反应,从而达到减轻免疫抑制和降低或缩短IR时间的目的. 相似文献
