Mindblowing. Thanks a lot for this

@39:34 "tDCS in its own not much of an effect. tDCS on an active system has an effect...tDCS should not be applied on its own." why this statement is not on bold letters on the package?

[@debir4111]

That was my first thought too, it seems REALLY important, so why is it glossed over with the Neuromyst manual?

amazing lecture. Thanks a lot

Hello Doctor! My recently high functions/honor student teenage nephew has been diagnosed with Deficit Disorder Schizophrenia. He's almost 18 & is now not independently functioning at school or socially. Doctors want to switch him to Clozapine. Can tDCS help him & give us some much-needed HOPE? I'm researching all I can to looks for an alternate/cutting edge option, that isn't tons of medications. Please reply and direct me where to look, who to call that might be an expert on this technology for schizophrenia. Thank you!

i'm planning to buy a FLOW unit second i have the income for it. but the attraction for me is knowing it's how the brain works EM and i believe it's possible to trigger sensory feedback eventually creating sound vision touch taste and smell in a simulation.

Would be great, but it could be nervy too to e. g. see your auditory experience all the time...

[@kevinburke544]

Is there any commercial TDCs worth buying or are the likes of Alpha stim just a scam?

Google Flow neuroscience, that seems to have a lot of good reviews

Can it help with derealization as well?

I might have missed it but was there any data specific to differences between left/right handed subjects regarding montage orientation?

[@aurasensor]

I heard this makes quite a difference. So everyone may try to reverse polarities to ckeck out what is best for him

I need this for my daughter! Please tell me where I can find someone in Oklahoma City area. TIA God Bless.

I bought the omni stimulator from there website. Its affordable and has been working well for me.

I don't doubt anything you are saying sir, but I would like to point out one small thing from an electrical perspective, and this may be nothing or it may change the way that you look at the evidence collected. Electricity flows from ground. In other words the electrons move the opposite direction than what you are portraying. Just saying.

[@MaromBikson]

Thank you. We define electrical flow as positive charge quantity (e.g ohms law). You are correct in metal (wires), electrons are the actual charge carriers and would flow opposite to this current flow direction. In the body, ions (both positive and negative) are the charge carriers. Please also see static1.squarespace.com/static/5cd3231cd7819e6ae55fedb4/t/5cfe9e5edde43a000159ce0d/1560190559668/Electrical+stimulation+of+excitable+tissue+design+of+efficacious+and+safe+protocols..pdf

@@MaromBikson If anodes induce hyperpolarization, and cathodes depolarize it, does that not mean the cathode is where all the activity takes place?

[@MaromBikson]

@@rhetoric5173 Excellent question. Current that flows into a neuron (from outside to in) will produce hyper-polarization, while current that flows out of a neuron (from inside to out) will produce depolarization (remembering we are thinking of current flow as a positive quantity, so this directionality respects ohms law). The key idea is that (because of another electrical idea, the conservation of current) any current that flows INTO a neuron must flow OUT of the neuron at another location. And vice versa. This means that in all electrical stimulation, including tDCS, there is no such thing as a ONLY depolarized or an ONLY hyper-polarized neuron. Rather, every neuron has some parts (some compartments) depolarized and some compartments hyper polarized. It is generally the case that the neuron parts (compartments) nearer the anode will hyper-polarized. And neuron parts (compartments) nearer the cathode will be depolarized. You can also think of it as neuron parts (compartments) pointed toward the anode or cathode. I talk about it more in this video kzbin.info/www/bejne/jYGoaKCLaNKsnM0

@@MaromBikson Thank you for your detailed answer professor, I have watched the seminar there and also the shared mechanisms of tdcs, tacs and temporal interference. In regards to Cellular Mechanisms of Transcranial Direct Current Stimulation lecture: The increase i inhibitory activity is remarkable and something i never considered though was aware of, given the number of variables involved into this I can see how cathode stimulation is more than it would appear, by decreasing the inhibitory activity, does this allow for more modulated activity in deeper regions? I understand that this is a very difficult question, but I had always been mostly interested in Gamma activity, and the recent findings about gamma desynchronization in outer regions is folloed by synchrony in deeper regions was quite fascinationg, some researched applied cathodal stimulation to the left hemispehre and it produced some rather interesting results with regards to cognition as opposed to anodal stimulation. Yutube is deleting my comments so i dont think I can post links or cite papers here. But how would that factor into the given dichootmy between anodes and cathodes? I also had the obvious question of how would TACs factor into this, is it possible to induce phase locking through TACs, and after watching the lecture here it seemed that using TDCs and TACs concurrently would produce the best results, though I'm not sure how anode and cathode would function into it, it would be a very complex theoretical challenge to figure exactly what is going on and factoring in the anatomy adds several further layers (personally I cant help but feel TRNs is the most functional due to intractible complexity at the time being). Seeing the second lecture regarding temproa; intereference, I'm not sure of anode-cathode placement presented in the paper, how are are both sides stimulated concurrently? The subharmonics section was also very interesting.
