Signal to Noise — BrainKit:A Combination Brain Mapping and…

You’re more likely to know Nathan Whitmore as /u/ohsnapitsnathan, one of the moderators at the tDCS subReddit. Around making plans to attend NYC Neuromodulation Conference 2015, he’s started a GoFundMe campaign and announced an early Beta of his tDCS device, BrainKit. It’s a very ambitious project! He plans to include sensors that would  monitor brain activity using capacitance (Electrical Capacitance Volume Tomography)! The BrainKit would then generate optimal montages for specific desired effects! It’s Arduino based, and Nathan intends for it to be Open Source. It’s very early in the BrainKit’s development, but it appears to me that all the pieces are in place.

A feature new to BrainKit is the ability to act on this information by designing a montage. BrainKit’s montage designing algorithm is actually quite simple, and based on the principles that:
1. If increased performance on a psychometric measure is associated with higher excitability in a cortical area, BrainKit will deliver anodal stimulation to that area, if decreased excitability is associated with increased performance then BrainKit will use cathodal stimulation.
2. If functional connectivity between two electrodes is positively associated with good performance, anodal stimulation is delivered to both electrodes, if it is negatively associated with good performance then cathodal stimulation is applied to both electrodes.
3. If any electrode conflicts exist the previous two rules cause one electrodes to be marked for both anodal and cathodal stimulation, that electrode is excluded from the montage.

  1. i am a single mom who suffered a traumatic brain injury in 2002. i spent a while in the hospital and when i came out of a coma and was transferred to a brain injury rehab facility for inpatient therapy, followed by about a year of outpatient therapy. since i have done quite well, yet with ever increasing stimulant medication. i took concerta and ritalin for about 13 years and now have recently transitioned to adderall xr and adderall. I homeschool a 16 year old daughter with an interest in science. i am hoping to build a tdcs device and would like guidance on most helpful placement of the electrodes.
