无创non-invasive fMRI(functionalmagneticresonance,功能核磁共振成像) 原理:扫描仪会测量磁场中由血氧(blood oxygenation)变化引起的空间扰动,当大脑的不同区域变得活跃时,血液会流向活跃区域以支持其神经活动,这提供了大概一立方毫米尺度的活动度量,这是对数万个神经经元的平均活跃程度的测量。 方法:用不同颜色展示...

a study that took the help ofFunctional MRI(fMRI) revealed that people catching ASMR videos experienced increased activity in different regions of the brain. This was, in turn, associated with reward activation, self-relevant thoughts, somatosensory...

是什么让我们会“渴求异性”呢?费雪针对人类的大脑,进行了革命性的研究:她公开征召“恋爱中”的学生,并以核磁共振造影机(FMRI)扫描学生的脑部,以检测他们脑部血流不断变化的模式──活跃的脑细胞会比不活跃的脑细胞,明显的需要更多的血液,于是可以清晰的观察出,人在“深陷爱河”时,会经历哪些脑部变化?
Of course, MRI only shows us a static image of the brain – an anatomical image, not of the brain’s actual activity. So how can we get an image of the brain activity? This is where fMRI comes in. What about fMRI? If I want to move my right arm, a few things need to happen....
例如,在MEG的一项研究中,真实的面孔在130ms时产生了比脸一样的无生命刺激更大的反应,但在刺激开始后165ms产生了类似的反应。在fMRI实验中,FFA的反应模式,而不是LOC或PPA,与无生命刺激的面部特性相关,表明面部选择性区域被调到非面部刺激,从而产生对面部的感知。
These specialists focus on the relationships between the brain's structures and behavior. They often use imaging techniques, such as positron emission tomography (PET), single photon emission computed tomography (SPECT), and functional magnetic resonance imaging (fMRI), to study brain functions. Clinic...
This is used to see whether there's cancer in your prostate and if it's spreading, as well as to evaluate other issues like an enlarged prostate. fMRI A special kind of MRI called a functional MRI (fMRI) maps brain activity. This test looks at blood flow in your brain to see which ...
