For a long period of time we didn't know anything about that brain. That's because it's extremely hard to measure changes in electric signals that indicate brain activity.
Scientists had to wait until 1992 for the invention of functional Magnetic Resonance Imaging (fMRI) in order to observe brain activity.
This video was made for the www.fastforwardscience.de competition, but is and will remain freely available for all interested in learning a bit more about how brain scientists use for their work.

Das Gehirn war für eine sehr lange Zeit ein Mysterium. Das liegt daran, dass die elektrischen Ströme, die Aufschlüsse über die Funktionsweise des Gehirns liefern können, extreme schwach und schwer zu messen sind.
Wissenschaftler mussten sich bis 1992 gedulden. Die funktionale Magnetresonanztomographie (fMRT) ermöglicht den Blick in das aktive Gehirn.
Dieses Video erklärt, wie fMRT funktioniert und zu welchem Wissen über das Gehirn es uns verholfen hat. fMRT bleibt ist auch heute noch ein Platzhirsch unter den Methoden der Neurowissenschaftler und wird auch in Zukunft vieles über das Gehirn in Erfahrung bringen.
Dieses Video wurde für den www.fastforwardscience.de Wettbewerb produziert, bleibt aber weiterhin für alle zugänglich, die Interesse daran haben zu lernen, was die Hirnforschung so alles macht. - Krátké a kreslené filmy
After the class on fMRI, I was like "what??? What just happened in the last 90 minutes?"
After watching this video, I'm like "OHHHHHHH. OH OH OH"
Many thanks!
And because I felt just like you after some of these lectures I made this video :-D
Haha same
exactly my experience, except, it was an online class, i ended up watching half of it in my sleep.
Wow, just perfect! Easy to understand, condensed and on-the-point, garnished with very nice Animations! Thanks a lot :)
That was my intention!so glad i got my points across. Thanks for the feedback!
+Mikio Herzberg Thanks for the vid. Glad I found this. I'm looking for inspiration because I have to present some fMRI studies in a few days to get a teaching recommendation ^^
Yes animation was key to helping with understanding.
your way of explanation is really comprehensible
Brilliant video, Philipp! Keep them coming!
I recently completed my PhD in psychology/fMRI and I'm now going to start a postdoc using fMRI data. Despite being kind of an expert in the area, I'm still amazed by how it works, and still watching this video from time to time. The best short explanation of this technology out there IMO.
WOW, I have STRUGGLED with this concept for SOOOO LONG, thank you Mikio - it was simple all along!!! You made that very very clear and now I feel very confident for the imaging part of the exam.
This is EXACTLY the type of explanation I was looking for. REALLY WELL DONE! I understand the mechanisms behind fMRI a lot better now. THANK YOU!
Honestly the best explanation of fMRI I have come across so far, much better than the textbook I am currently reading. Thanks a lot!
Excellent job, Philipp! Good luck!
Recently started in a lab with fMRI topics, this is very well explained and easy to understand. Thank you!
Great job Philipp!! This should continue long-term :)
Wow, very impressive video, I particularly enjoyed the visual aspect of the video with use of excellent animations. Thank you for making this subject more approachable for us doctors who are not radiologists :)
My Man, you're just saving my exam in Methods of psychology
Exactly what I was looking for. Thank you very much Mikio!
Great video! Really liked the animations and the analogies you used :)
You get the talent of a great teacher, explain things simple and clear. Thanks.
Good job! Very cool insights into how the fMRI works. I was in one last year and was actually curious how it functions.
Amazing!!! can you please make more videos ! This is the best youtube i've seen in my 27 years of existence
what an amazing video. you're exceptional at explaining difficult stuff. You should get so many more subscribers
This video is amazing! You are amazing!! The way you were able to condense the 2 page garble in my textbook in a mere 6 minutes- Thank you so much!!
Great explanation of a complex topic!
Really good explanation, Philipp. You will be a great teacher!
Great job. Visualization - full points! , analogies for better understanding - full points.
Brilliant explanation man! Helped me a lot. Thanks a great deal.
Very nice - pretty sophisticated explanation of how fMRI measures brain activity, made understandable.
OMG SUCH AN AWESOME VIDEO. Thank you so much for your help!
Great job!!! Nice video editing too!
Finally a video that makes the mechanism behind fMRI easy to understandI! Thanks a lot :)
Thank you, this is so clear!!
Well done explaining such a complicated topic.
thank you so much for the video it helps me a lot understanding how fMRI works!
Thank you so much! I am organizing a journal club for undergrads and this is the perfect place to start!
doing research for a project on fMRI... thanks for a great introduction to the topic!
Very well explained with excellent animations and metaphors! Good job!
Great video Phillip! Good luck :)
Great explanation, helped me a great deal to understand the workings of FMRI. Thank you.
Brilliant. Very well communicated.
Great job at explaining. Makes it easy to understand thank you!
Thank you! Fantastic video, clear explanations and great animations. Even a Pediatrician can follow the Physics of all things technical! Keep up the good work.
This is very helpful! Thank you for sharing!
best explanation ever , thank you
Really cool!!! Interesting and understandable for all ages!!! You have a gift :)
thank you so much for your easy to follow explanation!!
great job my friend!!!! keep working its going well!
fantastic! I understood more from this than from 4 hours of physio lectures at uni
Great job with the video!!
Way better and more passionate explanation than my prof
This is amazing! So easy to understand for non-native english speaker like me 💓
Outstanding explanation, thank you :)
FANTASTIC! Thank you!!
Thank you so much for this. Great explanation.
Excellent video, thank you very much. Very very helpful!! :)
Really helpful. Thank you!
That was excellent! Thank you! I am teaching an enrichment course for IB students in Brazil giving them an intro to Neuro-sciences and this video will be very helpful to show them how the brain is studied and how we can say the things we say about the brain and its functions. :)
Yes, there was simply no video that would explain it properly. So after 5 years of studying neuroscience and not understanding exactly how fMRI works I just had to do this! I'm glad you find it helpful!
Wow!! I never understood it until now!
Awesome :)! Can't imagine how one could explain it better!
Really helpful video! definitely helped with my exam revision :)
Amazing explanation!
The last sentence of the video gave me a goose bump.
WOW nice explanation. Thanks!
A great video ! very simple explained !!!
Beautifully explain!!
Amazing video .... very precise and in generic science terminologies... thanks for that.
Very Nice Video! Thank you!
Thank you for your gifted presentation
Very helpful! Thanks :)
Thank you thank you so much!!! Very clear and impressive! Thank you!
Awesome explanation
Thanks for this amazing video
Very charismatic amazing speech about this complex topic. Very good! :)
Yes!! Using the human brain to study the human brain...mind blown. My favorite thing about this discipline.
Awesome video!
Amazing explanation
My God, thank you for that. I get it now. The visual and examples that were given made your explanation of the topic understandable.
great edit!
Thank you! great explanation
Great work Bro..
excellent explanation..
Absolutely brilliant!
Great explanation, science easy to understand !
thank you soooooooo much for this great video
Thank you sooo much!!!
Incredible explanation, much better then that of my professor medical imaging!!
Awesome video, you explain so well! Thank you so much! I subscribed
Great video!!!
Thank you! This was amazing
Thank you so much!
Great job!
Really well explained, thank you! I would suggest to turn the volume of the music a bit down next time, but all in all very helpful :)
Vielen Dank für die super gute Erklärung!!! :)
Sehr gerne :-)
really insightful
Wonderful thank you!
brilliantly explained! thanks a lot Mr. Mikio...I wonder if you could also post a video on fNIRS too...
Waw THANK YOU SO MUCH !
really liked it!!!
This is the best BOLD explanation I have ever listened to. No matter how much literature I have read, I always come to this video for clarifying my mind on BOLD. Thank you very much
Very happy to read your message. 5 years of neuroscience courses didn't clarify to me how BOLD works. This video was born out of that frustration
Good stuff!
Great video
That was clear and to the basic understanding. Can you give a roadmap of how to start working over fMRI Analysis for a beginner, if possible. Will really help many like me to start over...
this is so good why do you have only one video like this
Because that video took me 2 weeks of day in day out work. But maybe I'll come back to making videos one day - I teach science at a school now.
@@ScienceOfTeaching That is nice. I hope you the students enjoy your teaching!
Muito bom! Obrigada!
