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.

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.

tDCS For The Masses – Foc.us ‘Go Flow’

Update 2/29/16 Some details of operation I borrowed from the Foc.us rep on the tDCS subReddit.

Yes, you can do any combination of time and current between the minimum and maximum limits.

The current level can be set from 0.5mA to 2mA, and is indicated with ORANGE lights. Pushing up or down the rocker will change the value in 0.25mA steps. e.g. 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2mA.

Once the current is set the lights change to GREEN. This is to set the time and pushing the rocker up or down will change in increments of 5 mins e..g. 5, 10, etc.. to a maximum of 35 mins.

Once you press to confirm the time the session will start. There is a slow ramp-up of current at session start for comfort. The gauge will now change from ORANGE to GREEN every 5 seconds.

During an active session the lights will show you the actual current value or approximate time remaining. Using the same Orange for current and green for duration scales.

If you find the current level too low or too high, you can change it during an active session. Simply press the rocker up or down – but please note the current will be ramped for comfort, so wait for each change to take effect. The lights will instantly change to orange to show you your changed level.

Changing current during active sessions is in 0.125mA steps for fine grained control and accuracy. You can see these hard steps by half lit lights. The current level shown on the ORANGE display is the actual, accurate current.

You can click the rocker during an active session to stop and the current will ramp down and off.

“Does it taper down the current over time, or will it be at a constant current over time?” no, this device will not give you incorrect current, neither too low, nor too high. It will be accurate from start to stop. It will not fail just because you have used the wrong amount of salt or your own choice of electrodes or any of the other things that trip up other devices. If for any reason the device detects it cannot maintain the target current, the LEDs will flash green/orange and the session will be stopped.

At focus we believe that the first job of a current stimulator is to produce an accurate safe current. It is staggering that this is considered optional by other manufacturers.

I think you’ll find its a really simple device to use and operate.
If it flashes orange and green – that means the headset is not connected. If it flashes just orange, that means it cannot reach even 0.5mA. This means the resistance somewhere is too high, usually the pads. Please try with fresh pads and problem should be gone.
