Bring On The Neuro-Revolution!

Not tDCS, but fascinating. Greg Gage @phineasgreg of BackyardBrains demonstrating a device that allowed one person to control the arm of another. I especially like his closing remarks,

This is what’s happening all across the world, electrophysiology, bring on the neuro-revolution.

Treatment is achieved by sending a low electrical current to the area of the brain in question via the electrodes for about 20 minutes, repeated over a number of sessions. Apart from a 15-second itching sensation, Maiques says that patients do not feel anything during the process. By exciting the neurons with the current, it has a positive effect on the rehabilitation of people with strokes in combination with physical therapy.

“You are artificially helping the brain to get more excited and more dynamic doing that task,” Maiques says. “Studies show that if you do this in combination with other therapies you have more of an effect. In a sense you are teaching the brain to behave in a different way. And then it is learning that behaviour.”

Neuroelectrics wants to be Fitbit for the brain

We met Ana in our first podcast interview.

Maiques compares Neuroelectrics to the “DIY” ethos of health-tracking technology, such as Fitbit and other wearables. “We have an ageing population dealing with chronic illnesses, but people are also becoming more self-aware when it comes to monitoring their health. We believe these self-monitoring technologies are going to become popular in the home over the next few years.”

New Products From Neuroelectrics

We met Neurolectrics in my first podcast interview with Ana Maiques. They created Enobio, a wireless multi-channel EEG cap, and Starstim, which adds tDCS (tRNS, tACS) alongside of EEG monitoring. They also make a powerful suite of software for controlling and monitoring their devices. They’ve recently added a few new products and some updates. They also have a blog!

New Stuff!
Enobio 32: EEG Cap now in 32 channels.
Neurosurfer: Combine 2D & 3D (inculding Oculus Rift support) Neurofeedback games.
Starstim Home Research Kit: Allows physicians to facilitate telemedicine tDCS sessions.
Starstim tCS: Starstim without EEG.
NUBE: Cloud data management for your tDCS and EEG studies. (Neuroelectrics has been distributing Starstim devices at the university research level for some years. We should assume they’ve collected a lot of fascinating data.)starstimNew

How Electric Currents Could ‘Boost’ Brain | Sky News

“The research so far shows that when we use tDCS you can, in some cases, improve performance,” he told this week’s edition of Swipe.

“It depends on several parameters like the type of the current that you deliver, where you put the electrodes on your head and the timing of the stimulation.”

It is thought the technology could also be used to help people with ADHD and potentially treat depression or conditions like Parkinson’s disease.

Dr Kadosh said the research so far showed that tDCS is risk free.


tDCS clinical research – highlights: Cognitive Enhancement | Neurolectrics

Neurolectrics (Starstim device) published a white paper (pdf) in October 2013 that nicely collects pretty much all we know to date about tDCS and cognitive enhancement. I was reminded of this while visiting their montages page on their new wiki. Quoted is from the Chi / Snyder 9 Dot study (pdf).

Brain stimulation enables the solution of an inherently difficult problem – Certain problems are inherently difficult for the normal human mind. Yet paradoxically they can be effortless for those with an unusual mind. We discovered that an atypical protocol for non-invasive brain stimulation enabled the solution of a problem that was previously unsolvable.The majority of studies over the last century find that no participants can solve the nine-dot problem – a fact we confirmed. But with 10 min of right lateralising tDCS, more than 40% of participants did so. Specifically, whereas no participant solved this extremely difficult problem before stimulation or with sham stimulation, 14 out of 33 participants did so with cathodal stimulation of the left anterior temporal lobe together with anodal stimulation of the right anterior temporal lobe. This finding suggests that our stimulation paradigm might be helpful for mitigating cognitive biases or dealing with a broader class of tasks that, although deceptively simple, are nonetheless extremely difficult due to our cognitive makeup

Ana Maiques of Neuroelectrics – DIY tDCS Podcast # 1

Well here we go! Episode one of the DIY tDCS podcast. Ana Maiques is co-founder (with Giulio Ruffini) of Spanish-based Starlab. Their spin-off company, Neuroelectrics makes Enobio, a research-quality wireless EEG device, and Starstim, a multi-channel wireless tcs & tDCS device. Download the interview here (zipped mp3). Show notes after the fold.

(If you speak Spanish you might enjoy the interview these photos were taken from.) Also, if you’re an EEG or tDCS researcher or clinician (or VC) on the East Coast, Ana is frequently in the New York and Boston area and is happy to discuss Enobio and Starstim. Neuroelectrics will be at the Advances in Mediation Research conference in NY Jan. 17 2013. (Schedule)  Check out the Neuroelectrics blog for excellent tDCS and EEG info.

Starlab is the parent company > Space (sensors) + Neuroscience
Cutting edge research > impact on society… products and services
Twelve years of research in neuroscience > Enobio, Starstim
Initial market is early adopters – researchers, clinicians and practitioners
Starstim (tDCS) > chronic pain, stroke rehabilitation (later… depression >> cognitive enhancement, addiction)
Medically certified in Europe and Canada
Filing 510k for Enobio in the US
Starstim has 8 channels for use as HD tDCS but can also use traditionally
Can also do tACS (alternating current), or random noise stimulation and at the same time Simultaneously record EEG
Can also use dry EEG electrodes
Roi Cohen Kadosh Oxford study, kids etc. (Link to video we discussed. NewScientist)
Study will determine if tDCS is efficacious in enhancing performance in certain areas (math)
Will have implications for people with Alzheimers
Partnerships with 15 hospitals doing research with Starstim
8 in U.S. and 7 in Europe. Different pathologies. Results to be published soon.
Post-stroke rehabilitation is a great place to see the effectiveness of tDCS
tDCS > Motor recovery… hand rehabilitation…
Can thereby measure the degrees of movement and improvement very objectively
Couple of groups showing very measurable results.
The Muse, Neurosky, Emotiv Home EEG devices?
Limitation is number of channels.
Started Enobio with 4 channels, but feedback from medical community lead to  developing a 20 channel Enobio.
For certain applications – games, BCI etc, the home EEG devices might be fine
But we’re looking at the medical application of EEG.
Doctors and researchers require the maximum coverage of the head.
Signal quality is very important.
EEG application
Emotion recognition, neural marketing, traumatic brain injury – concussion

Is tDCS Safe? –

This comes to us via the blog. I’m very excited to see Neuroelectrics on the scene. I first noticed their device Starstim (pictured),  popping up in news around Roi Cohen Kadish’s ongoing tDCS trials at his Oxford lab (see). I believe Neuroelectrics is a Spanish company. What’s especially exciting to me is that they also make an EEG device called Enobio and are working on the ability to map brain activity with EEG while undergoing tDCS. Think about that! Live, in-the-moment feedback on exactly what effect your tDCS is having.

More than 100 studies have been performed using tDCS in healthy controls and in patient populations, and no serious side effects have occurred for a review, see Nitsche and others 2008. Slight itching under the electrode, headache, fatigue, and nausea have been described in a minority of cases in a series of more than 550 subjects Poreisz and others 2007. Detailed studies have been performed to assess the safety of tDCS. These have shown that there was no evidence of neuronal damage as assessed by serum neuron-specific enolase after application of a 1 mA anodal current for 13 minutes Nitsche and Paulus 2001; Nitsche, Nitsche, and others 2003 or MRI measures of edema using contrast-enhanced and diffusion-weighted MRI measures after application of a 1 mA current for 13 minutes anodal or 9 minutes cathodal; Nitsche, Niehaus, and others 2004 […] In addition, a recent study was performed in rats using an epicranial electrode montage designed to be similar to that used in tDCS Liebetanz and others 2009. This demonstrated that brain lesions occurred only at current densities greater than 1429 mA/cm2 applied for durations longer than 10 minutes. In standard tDCS protocols in humans, a current density of approximately 0.05 mA/cm2 is produced.
