Talk Abstract: Few emerging therapies for neuropsychiatric disorders has engaged as much excitement and also debate as transcranial Direct Current Stimulation (tDCS). To identify the potential of tDCS and move beyond the hype, this talk addresses the technology and cellular foundations of tDCS. For decades, it has been established that direct current stimulation can modulate plasticity; new research is unraveling the cellular mechanisms of how direct current stimulation can produce nuanced and targeted changes in brain function. Over the past decade, the technology of tDCS has advanced from basic clinical stimulator using two electrodes to High-Definition tDCS (HD-tDCS) using arrays of electrodes and to Remove-Supervised technology for home use. These new technologies have allowed categorical enhanced in the targeting (HD-tDCS) and deployment (Remote-Supervised) of tDCS. Finally, new approaches to optimize tDCS using imaging and biomarkers, including used EEG reciprocity, have provided new insight on therapeutic mechanisms as well as rational methods to select patients and individualize tDCS. The thesis of this talk is that tDCS is grounded in well-established biophysical principles but that emerging technologies will support robust and efficacious translation to patients.
thank you
so it seems electromagnetic waves which resolve to current ie TCMS. are more effective no?
What target area is for OCD ?
18:30 Was a very interesting slide. After learning about TDCs for quite some time now, and am now building my own device. Could you elaborate on some of the dangers and easiest studies with profound effect to conduct with a home made device?
Also, I'm aiming at regulated 2mA at 5V, does that sound correct?
Build in a constant ammeter, so you can tell if you're getting fluctuations or other issues. Buy a multimeter and calibrate your ammeter periodically. Without calibration the ammeter is useless and misleading. Build in a knob connected to a potentiometer so you can ramp up to treatment amperage (you want to start with 0 amps and increase to 1-2 mA over a few seconds to avoid discomfort and potentially damaging phosphenes). If I had it to do over again, I would build in a process that slowly ramped to treatment voltage automagically. I thought my head would provide significant resistance, but it's almost negligible. I power my machine with a 9V battery and it's plenty. I suspect 5V would be fine. I am NOT a doctor nor an electrician.
@@chaosordeal294 thanks!
@@chaosordeal294 thank you very much for the detail in your post.
Do you know a good place I can learn The difference between tdcs and CES?
I see a lot of CES devices and they look simpler for me to use because I'm not technical at all.
And on your opinion, what percentage of benefit for mood disorders do you think someone could get from CES vs tdcs?
thanks a lot for your any advice you can give. I've just struggled a lot, and I'm doing my best to self-heal. I welcome any advice. All the best, Thomas Seattle Washington USA 😊
I had an eeg at my wellness senter and the whole top was red? Can you tell me what that means?
It literally just means a color. It could mean 2 very different things such as over stimulation or lack of. You can normally change the colour in these programs so no need to worry.
