This project aims to produce real time dynamic cognitive enhancement by combining functional brain mapping with neural plasticity enhancing transcranial magnetic stimulation.
This is to establish existing bodies of research on noninvasive techniques to first monitor brain activity through low resolution electromagnetic tomography(EEG, LORETA) as well as the effects of Transcranial Magnetic Stimulation (TMS) on, learning, neural plasticity, and neural disorders.
- Lights coded to brain region and/or type
- Robots that are attracted to lights of certain color (possible projected simulation)
- Light visualizations a la Turrell
- Positive feedback loops
- Inside your brain
- See Turrell, but have environment react to changes in stimuli
I just type up a sweet paragraph on this aspect of the project only to have it completely erased during an upload. Damn. Anyway at this point we've forgone the attempt at making a functioning Transcranial Magnetic Stimulation aspect of the project (we will continue to prototype it out side the exhibit component) and are focusing on the low resolution electromagnetic tomography and coupling it with an interactive aspect for the show. We intend to model an anatomical correct sized Human brain and imbed a wireless interaction with the EEG cap to have a visually active LED array to give the wearer a real time mapping model of their actual brain wave activity. To do this we've reached out Brown's Brain Research Institute to borrow an anatomical model for casting purposes as well as spent hours in the RISD Material Library researching the various , Urethane, Silicon and Polysulfide rubbers to reproduce out model with. Right now we are awaiting supplies to be shipped while initial work is being done of the programing and hardware, progressing as the hardware arrives. (the pictures above are from RISD Material Library)
In order to place the Arduino inside the model of the brain we need a sealable enclosure in which to put the board. I'm using a convex hull of a brain model and OpenSCAD to create a basic model of a case which could then be placed within the brain mold.
For the case to fit into the brain mold, it must be scaled down as much as possible, leaving at least one inch free for the material to provide its unique consistency. However, the case must also contain the Arduino, XBee, and battery, making this a delicate balancing act. On the picture above, the outer grey box is the bounding box of the brain and the inner box is the bounding box of the case.
With the assistance of Ryan we able to achieve an early functional model of the set up, reading his brain wave activity while displaying it on the model brain in hand. This is phase one of the projects main goal of coupling the monitoring systems with TMS enhancement and will represent in a refined form the interactive components of the exhibit on the 15th.
