brain
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.
Previously I said I was developing a ROI analysis program (https://www.alivelearn.net/?p=1421). Here it is: Download main program (beta version) at https://www.alivelearn.net/xjview/xjviewpro/xjviewpro.p Download sample input excel file: https://www.
Quite often you need to convert the coordinates of some voxels in MNI space to regular matrix coordinates. Below is a script to do so: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% mni2cor %%%%%%%%%%%%%%%
Can you find any pattern in the two signals, green and blue? The blue signal is the brain wave (measured by NIRS) of a person when he is pressing some buttons (the timing of button pressing is shown in the vertical lines); the green signal is also br
Check out the program: https://www.alivelearn.net/?p=1439 This program has a very simple graphic interface – only 2 buttons. The ‘load data’ button will ask you to load an excel file where you specify the path of images and event ti
