概括

对性欲望的神经成像研究受到不清楚的定义和对欲望和兴奋的类似范式的限制. 未来的研究需要更清晰的定义,不同的刺激,以及先进的分析,如连接性,以了解性欲望的大脑基础.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
性研究性研究性研究性研究

背景情况:

超过20年的神经成像研究已经探索了性欲望的神经支柱.
由于缺乏明确的概念区分性欲望,性兴奋和普遍接受的性欲望定义之间,文学存在混乱.

研究的目的:

批判性地审查神经成像对涉及性欲望的大脑区域和网络的研究.
识别有前途的大脑区域和网络,以了解性欲望.
为未来的研究方向提供建议.

主要方法:

使用现有的神经成像研究对性欲望,兴奋和爱情的元分析进行了审查.
通过谷歌学者和转发引文跟踪扩展了研究识别.

主要成果:

通常涉及的大脑区域包括杏仁体,下丘脑,条纹体,前带膜,胰岛和前额/轨道前额皮层.
对于性欲望和性兴奋所使用的范式往往是相似的,这阻止了关于特定欲望大脑区域的明确结论.
结论有限,原因是缺乏连接分析和未能考虑负BOLD (依赖血液氧气水平) 信号.

结论:

建议包括使用理论上不同的刺激 (色情与性明确).
为参与者提供关于性欲望和性兴奋的清晰定义.
谨慎地使用与事件相关的设计,对BOLD信号使用时间序列分析,并进行连接分析以映射大脑网络.

关键词:

有效的连接,有效的连接.功能磁力共振成像 (fMRI) 是一种负面 BOLD 粗体表示神经成像是一种神经成像.性兴奋性兴奋性兴奋性兴奋性兴奋性性欲的欲望是性欲的欲望.

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
