It seems quite terrifying, I admit. But in the moment it doesn't feel scary at all. I have had many participants that felt anxious before TMS, and were fully relaxed and calm during the stimulation itself.
Our science teacher did that on a couple of us in high school in the 80's. We all had a good laugh at the time, but looking back it scares the sh*t out of me!
When you blocked the Broca’s area, how were your mental states impacted? Were you still able to think through speech? What kind of thoughts were present?
Great question! It really looks scary, but it feels not scary at all. You can still think about all the words, they just don't come out. It feels kinda funny because something from the outside is making you behave weird, but at the same time you know, once you take it of, everything is fine. Of course, I done it many times, but I get the same responses from participants. Most think it is funny. Interestingly, when you try to rhyme or sing, the effect ot the TMS is almost gone, because using rhythmic speech is driven by other pathways in the brain.
What happens if you apply TMS over the Wernicke’s area? Do you become unable to read/process language or does it improve this ability? Can you do a video on this?
A very interesting question! You would think that is somehow relates to speech recognition. Interestingly, however, one study has shown that when TMS is given at a high intensity between 4 and 8 Hz, it can also temporarily cause speech arrest, in the same way as TMS to Broca's area does. This seems surprising since Wernicke is not directly involved in the output of speech, but my guess is that when speech formation (in Wernicke) is blocked, then no output can occur either. Now, this is just a demonstration effect. More interestingly are studies who have used TMS therapeutically, by applying rTMS. There are various studies that show that it can help people who suffer from aphasia. So, with the right dose and frequency it can also improve function of the Wernicke area. I will delve a little deeper into the literature and will make a video off that. I cannot promise you when it comes out though, because of my current high work load. Thank you for asking!
Hi, thanks for the video. Do you think that stimulating Broca’s area with TMS can unlock speech in kids with developmental issues? Which areas could be stimulated for unlocking speech? I’m doing my kid TMS to 10 and 6 areas and was wondering if we can switch to 44/45(broca)?
Fascinating! Is it possible to buy a tms machines as a consumer product? I have 20+ years history of periodical depression, and would like to try rTMS as a treatment. But is not available in my region in Denmark
I am afraid that TMS machines are not commercially available, at least not to my knowledge. Also, using them is not as straight forward as it looks, so I would always do it with a professional. It is unfortunate that no TMS treatment is available in Denmark, and it surprises me. I hope that will change soon.
If a patient has damage in Broca's would you place the device on a discrete area in the right hemisphere to stimulate cortical excitibilty in the language area in the left hemishere?
Great Question! There is a handful of studies that have found positive effects of repetitive TMS on verbal fluency. It should however be noted that these studies stimulated the prefrontal cortex, rather than Broca's area directly: doi.org/10.1111/j.1468-1331.2012.03699.x doi.org/10.1016/j.brs.2012.09.014 Stimulating Broca's area directly with TMS can be quite painful and is above the pain threshold for many people. So in many cases TMS over Broca is not an option. Interestingly, however, this study used transcranial direct current stimulation (tDCS) to target Broca's area, and also found positive effects on verbal fluency: doi.org/10.1016/j.neuroscience.2011.03.058 Given that there are a handful of studies, I would say that there is some evidence that TMS/tDCS can improve verbal fluency. But I would be cautious given the low number of studies and it would be great if there is more research in the future.
I'm curious if I had some cross-excitement to this area of my brain today during treatment. For the first time today I was suddenly unable to speak during the pulses just like in this video. I had major excitation in the motor strip too. Most intense spasms I've had! It was quite the Monday morning session. Lol Pretty wild technology
It could be, the region is not to far from the prefrontal cortex. But if the discomfort becomes to big, you should tell your tech? They can place the coil slightly different, or change intensity
@@real.psyched When the neurons in the brain are stimulated, they engage a natural phenomenon known as neuroplasticity. Neuroplasticity allows the brain to rewire itself and reassign damaged functions to other areas that were unaffected by injury. Therefore, by stimulating specific brain regions, magnetic therapy can potentially offer multiple benefits to patients after stroke. However, magnetic stimulation does not only target the injured side of the brain. It also targets the non-injured side. The reason behind this has to do with how the brain controls movement. Each side of the brain controls the opposite side of the body. This explains why a right-side stroke affects the left side of the body and vice versa. However, all movement requires cooperation from both sides of the brain. For example, to move your left hand, the right side of the brain must send an excitatory signal, and the left must send an inhibitory one. This ensures that movement remains balanced. Unfortunately, after a stroke, the brain loses this balance and can no longer send the correct signals. By stimulating both sides of the brain, magnetic therapy restores that balance
That is kind of terrifying but also extremely fascinating

You are welcome! :)
I saw this in Neuro class today. Very interesting!
It is really cool, isn't it?

Hi!
I find your video very interesting. Do you mind if I use it in a presentation (for the public defense of my phd) to illustrate the effect of TMS?
Glad to hear you like it. Yea, you can use it! Best of luck with your defense! :)
I have cerebral palsy and this treatment would improve most my symptoms If I had access to it
❤
That’s really cool
It really is!

Hello, Could I use your video in a TMS teaching course?
Absolutely!
@@real.psyched Thank you!

Thanks for your answer and the links.
what was the pulse rate and frequency you were being stimulated at?
Frequency in this case was 4 hz
What if he hits a point which prevents him pull that machine or his haed away? 😀
You could hit the motor region, but that would not block movement completely. Also, typically people don't do it on themselves, this is just a demo :)
In my experience, you'd be more likely to find a spot where you end up smacking yourself lol
terrifying
May look like it, but it is harmless

This 3 year month6 paralisis patient use or no please told me
TMS most likely is not going to help with paralysis. Sorry!

@@real.psyched I am see this rtms
Do the same test but give yourself 1 simple word to say
Maybe if I find the time ;)
