Hello, I am a Korean who also left a comment on your fnirs video. Please understand the use of the translator As I said in the video, I have to research fnirs or fmri for school assignments. But I found you because it was too difficult to find the material. You teach difficult things easily. But I didn't understand what you were saying because I didn't have subtitles. If you don't mind, could you give me a brief summary of fmri? I'm sorry. I want to know how fmri works. I need a summary of your video content. I don't have time, so please reply quickly. I'm really sorry
In short: blood with oxygen is attracted differently by a big magnet compared to blood without oxygen. The MRI scanner is a big magnet, so regions with more oxygen show up differently than regions without oxygen. And since oxygen reflects neural activity, the fMRI picks up regions that are active
@@real.psyched You are my lifesaver. Thanks to you, I can write my school assignments deeper and more concisely. Thank you so much I will improve my English by watching your videos often from now on
Hello, I was looking at the video in the hope of understanding what does the colors represent on an fMRI scan. If I understand correctly, the darkest red means more BOLD signal and the darkest blue means less BOLD signal?
In most cases that would be correct, yes. But the color scheme can be set to the researchers liking. Therefore, when you read a paper with figures like these, pay close attention to the legend.
