Fascinating stories of people with Aspergers who discover feelings and empathy as participants in TMS (Transcranial Magnetic Stimulation) studies. Begs the question, what if, as the effects of TMS fade, tDCS could be used to ‘top up’ their emotional awareness?
Frame of Reference From NPR’s amazing ‘Invisibilia’.
We all carry an invisible frame of reference in our heads that filters our experience. Alix and Hanna talk to a woman who gets a glimpse of what she’s been missing – and then loses it.

Market forces, the for-profit bias that imbues every aspect of health care in America, skew R&D towards solutions and products that are highly profitable. That’s one of the reasons I was so curious about tDCS. You can do it at home. It doesn’t cost a fortune. My initial curiosity was inspired by research papers that seemed to indicate the potential for cognitive enhancement, primarily memory and learning. Many papers later, I’m not so sure, but where it comes to tDCS and depression I’m much more confident. There does seem to be an overwhelming amount of both research and anecdotal evidence to support the use of tDCS in depression. If that were better known, perhaps someone like the woman featured in this NBC news clip would have had somewhere to turn when she was denied coverage for continuing TMS treatment for depression.
Eliza Strickland covered the HaloNeuro tDCS device. This clip shares my hopes about the Halo… that sports serves as a gateway until they can get established. IMO we need a device manufacturer with deep pockets who can satisfy the research and regulation requirements to make tDCS (or any other form of Non-Invasive Brain Stimulation – NIBS, that is effective) mainstream.
While the authorities dither, Halo will do its best to slip into the mainstream. And athletes are just the first customers targeted by this ambitious company. In South Carolina, a neurologist is currently testing the Halo with stroke patients to see if stimulating the motor cortex speeds up rehab. Chao envisions a whole range of Halo products offering consumers different kinds of mental boosts. “What if you want to learn Chinese and we stimulate the language center?” he says. “What if we stimulate the memory center and pair that with brain-training games?”
Just kidding. C’mon folks. The smallest bit of Googling… At least he doesn’t seem to have hurt himself.
NEVER connect electrodes directly to a 9 volt battery.
Sticky (TENS) electrodes are HIGHLY not recommended.
Based on his perception of the Sally Adee article/study featured on RadioLab 9-Volt Nirvana episode, YouTuber TheCharmIsGlobal attempted to replicate the experience in an experiment he called, “TDCS EXPERIMENT WITH CALL OF DUTY: BLACK OPS III” The 43 minute video is mostly onscreen playing of Call Of Duty, but he starts the video with a discussion of tDCS, applies tDCS as shown above at around 10:40, and declares victory at 42:50.
So the verdict is in, yeah, it does work! It really does work!
No mention of tDCS in his journey to find relief from severe depression, but some new to me and interesting information about treating his depression with Transcranial Magnetic Stimulation. Especially interesting is that a genome test recommended by his psychiatrist led to the awareness that many of the drugs typically used to treat depression would most likely be overwhelming to his system. Also that his insurer, Anthem Blue Cross (through the ACA, Obamacare) covered his TMS treatment. Links below to full article.
Transcranial Magnetic Stimulation, or TMS, is a depression treatment that was approved by the FDA in 2008. It involves placing a magnetic coil on the patient’s head, and stimulating neurons in a specific part of the brain known to be underactive in depression (the dorsolateral prefrontal cortex). Best of all, it has very few side effects: only some uncomfortable tapping on the head where treatment is applied. There are none of the standard side effects we’ve come to associate with medications.
There’s been a lot of attention to the Halo Neuroscience device, much of it around use by olympic-level athletes. Halo Sport is a VC-backed tDCS device that targets the Motor Cortex. We’ve covered it previously elsewhere on the blog.
