Sometimes we need to work on the surface of a brain. Here I create a surface mask based on the standard avg152T1 image (MNI space) for you to download. Visualized in xjview, you can see the mask in the yellow curved lines. It’s actually a surfa
This is the 6th post of the series: Handy programs to visualize NIRS data When we do an experiment, we often repeat an event (or block) for a few times. For example, in a typical finger tapping task, we ask the participants to do a finger tapping for
In my previous blog (https://www.alivelearn.net/?p=1426) and in our paper titled “NIRS-based hyperscanning reveals increased interpersonal coherence in superior frontal cortex during cooperation” (full text pdf available ), we have shown
饭店里，你拿着菜单，在思考是点西红柿炒鸡蛋还是尖椒土豆丝。这个问题显然很重要，因为你已经考虑了几分钟了。最后，你下定了决心，拍了脑瓜子，说，就要土豆丝了。你如释重负。旁边的服务员可能夸你，说你做出了最
我在读博期间做的研究是”人对时间的感知“，有些有意思的现象，权当饭后谈资吧。下面的研究是我的联合导师David Eagleman和他的学生做的。 —- 2006年一个普通日子的下午，王敏来
One particular nice thing about SVR is that the weight of each feature reflects the feature’s true contribution. If some features are highly correlated (this is common in neuroimaging data – e.g. adjacent voxel activity are very similar),
Note: I am not affiliated with Artinis and they don’t pay me for this post. If you also sell portable NIRS device and would like to demo to me, I am happy to see it. Marco, the salesman of Artinis, gave me a demo of their wireless/portable NIRS
Quite often you need to know what is the brain structure (anatomical name) of a given coordinate, say (-8, 2, 6)? Is there a program for this? The answer is yes. Please download the following matlab script: cuixufindstructure.m This program requires
Many users have created masks from a T-test image; xjView also allows you to create a mask based anatomy. Say, if you want to create a mask of Amygdala, how to do that? (You need to use xjview 8.10. 1 min video demo at http://youtu.be/31q_6jumhhM) 1.
