Extreme DIY – Transcranial Electrical Stimulator, Arduino Compatible | quicksilv3rflash

According to Instructables/reddit user quicksilv3rflash…

This device can be used for any kind of human electrical stimulation, such as tDCS, tACS, tRNS, or tVNS. Its hardware, when properly constructed and tested, limits output current such that -2.1mA < output_current < +2.1mA , based on the 2mA safety limit recommended in these published guidelines.

LED headset shows promise for Alzheimer’s, brain injuries | CITY News

Full Story: LED headset shows promise for Alzheimer’s, brain injuries | CITY News
This device/protocol is new to me, though I have been looking into Low Laser Light Therapy which looks promising. I will be looking into the science around this device, also its history, i.e. which came first, the device or the science.

Lew Lim, the founder and CEO of VieLight is seen explaining the device in the video.

The technology is called transcranial and intranasal photobiomodulation (PBM). Initial, small-scale results, are promising.

Five people, with mild to moderate Alzheimer’s, used the headsets every day for 12 weeks. The headset frame, with four different LED cluster-heads and an LED that clips to the inside of the nostril, was turned on for 15 minutes a day.

After the three months, neuroscientists noticed some patients, who were not able to speak in full sentences, could now put sentences together. Patients also experienced improved sleep and reduced wandering.

The device is called VieLight, (which does not include EEG which was used in the study depicted), seems to be available for sale. A smaller device, called the ‘Pocket Miracle’ is also for sale.

Caputron Announces New Version ActivaDose ll 29V 2mA Max Setting

Robin at Caputron sends word of their new ‘exclusively from Caputron’ ActivaDose 29V 2mA max Iontophoresis device. My one caveat with the ActivaDose had been the potential for user error in choosing a 4mA setting (rather than the 1 or 2mA setting traditionally used in tDCS research). This new device removes that possibility. This is the device you could confidently show your Mom how to use. The new version maintains the ActivaDose FDA approval for iontophoresis. This new version becomes the device I can recommend in all confidence, also because Caputron stands behind all the products they offer.

Focus announces EEG Dev Kit

Update 2/2/17. Focus just announced functional Near-InfraRed Spectroscopy (fNIRS) capabilities for their EEG Dev kit!

This was announced a few days ago and to be honest, I wasn’t sure what to make of it… a battery-looking EEG thing. Certainly I’m not a ‘Dev’ and so I left it to those who are to parse the details, still…  Ah, yes, further details arrived today via email I’m happy to share with you (below). I do get the feeling this will make EEG devs excited.

Update 1/19/17 The focus site now has a photo of their new dry EEG electrode.

Thanks for all your feedback and questions about the focus EEG. A common question has been what exactly is included (see below) and is it everything required (yes).

Included in EEG Dev Kit

  • foc.us EEG 24-bit 8-channel EEG with tES & Wi-Fi
  • 8 active dry electrodes for EEG, plus bias & reference electrodes
  • 2 active bio-potential electrodes for ECG, EOG, EMG or EKG
  • 2 wet tES electrodes for tDCS, tACS, tPCS or tRNS
  • 10-20 placement cap
  • Mains power adapter for recharging
  • Raw data access

Next week we will provide more details on the software and SDK for EEG processing.

Sincerely,
team focus

P.S. The first 100 66 are available at only $999 $499 – half price!

What I’m excited about is the Focus EEG headset, but a recent tweet exchange indicates we’re a good year away from release.

Caputron Now Carrying Focus GoFlow Starter Kit

Update 7/25/16 Caputron just announced their Banana Adapter for Focus Devices which facilitates use of Focus with Amrex or Caputron electrodes.

Caputron will be handling all Customer Support on GoFlow devices purchased through their site. At this time they have over 100 units in stock.

Spotlight on Halo’s Engineering: An Interview With Brett Wingeier, CTO | Medium

tdcshaloprimers

A big challenge for us has been: how do you get through the hair? Well, quite simply, with something that looks like a comb or brush. We engineered the primers to reflect a comb-like design — with rows of soft elastic foam tips called nibs. We spent the last two years coming up with the best shape, material, stiffness, angle, and geometry for these nibs, and then figuring out how to make them.

Olympic Athletes Are Electrifying Their Brains, and You Can Too | IEEE SPECTRUM

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?”

LucidCatcher – tACS Lucid Dreaming Device

Luciding is now taking pre-orders for the LucidCatcher. (Lots more on this site about lucid dreaming). Like much of the tDCS research, studies report conflicting results using tACS to induce lucid dreaming. Note that Foc.us has had a 40 Hz tACS mode built into their V2 device and also has a lucid dreaming kit. It’s been out long enough now that I would think that widespread success with using it to induce lucid dreams would have been widely reported. The LucidCatcher does come in a form factor optimized for sleeping. I’m curious to know more about the unusual electrode setup.

tdcsLucidCatcher

How does it work?

We typically see the dreams during REM (Rapid Eye Movement) phase. The device detects your REM and pushes mild electric impulses to the prefrontal cortex at a frequency of 40 Hz. It brings the logical brain back into service and makes you realize that you must be in a dream.

You’ll recognize the dream by millions of different signs that contradicts the reality because your consciousness evokes.

Not Quite A Take Apart – Nathan Looks At The Thync Device

I was happy to lend Nathan my Thync. I knew he’d get to the bottom of what exactly was going on. Especially in the context of exploring TES, pulsed wave forms and some of the older technologies I’d recently been made aware of in my interview with Anna Wexler, I knew the Thync device would represent the state of the art. Jamie Tyler had arranged for me to have one, most likely in my capacity as a blogger and reporter of all things related to neurostimulation. I myself did not experience any significant effects using the Thync though I did find myself using it frequently – mostly the Calm vibe. Was there some effect lying just below consciousness that my body was reacting to? Certainly nothing like the experience Manoush Zomorodi had trying Thync for her podcast episode Forget Edibles: Getting High on Wearables (really a must hear).

Focus Posts ‘Before You Get Started’ Page For DIYers

tdcs20160512-2Focustry-tdcs-largeFocus has posted a new page on their site which directs new users to show caution in their use of DIY tDCS. Focus goes so far as to caution people under the age of 18 not to try it.

If you are under 18 you should stop here. tDCS is not suitable for children and should not be used. This is because your brain is still developing and you don’t need to mess with its neuroplasticity.

The page goes on to list the known risks and a few benefits. Interestingly, it does not mention depression. I would have to imagine due to the possibility of crossing that nebulous regulatory line around ‘medical devices’.

Focus is, as I understand it, in the midst of fulfilling orders for their GoFlow device. You can read a full review of the GoFlow on SpeakWisdom, the (primarily) tDCS-related site authored by Dr. Brent Williams. Go Flow Pro, Nice Brain Stimulation Kit!

Self-Administered Domiciliary tDCS Treatment for Tinnitus | Sooma Medical

Unfortunately the study found little to no benefit (no more than sham) using tDCS with two different montages to treat tinnitus. What is very interesting however, is that the study allowed participants to administer tDCS at home.

A Sooma tDCSTM device (Sooma Oy, Helsinki, Finland) was used in the study. The device is designed and approved for patient use with pre-programmed treatment parameters and hardware-level safety limits. Patients were given a package consisting of the stimulator unit and stimulation electrodes (consisting leads and pads) along with three pairs of sponge pouches for the electrode pads, a head cap with openings for the electrodes (Fig 1), a chinstrap and 0.9% saline solution.
