Virtual Dictionary


Micro-ECoG is a form of ECoG, or electrocorticography. ECoG normally uses the same type of electrode mesh as EEG, 2-4mm in diameter each, and encased in metal. Micro-EEG, is a method of using multible individual fibres wrapped by a silicone disc, as a separate array in place of each normal ECoG electrode. This method has many advantages. Increased fidelity and the ability for long term implantation amongst them.

Typically, Micro-ECoG uses 16 ? 32 electrodes for every one that ECoG would use.

ECoG, or electrocorticography is a method of brain-computer interaction, in which a mesh of electrodes is placed like a veil, directly over the outside of the brain itself. MicroEcog, as the name suggests, is an order of magnitude smaller, and much more permanent.

Cosmic Rays, Micro-differences, and Virtual Worlds
One of the strangest things you notice with social virtual environments, where you have vast numbers of people coming and going, and using the exact same software to visualise the virtual world, is the sheer number of amazing, unduplicatable-by-anyone-else problems that are encountered.

Electrocorticography Grows Up
Electrocorticography or ECoG is a method of neural interface in which an electrode array, quite like a fine mesh, is draped over the upper surface of the brain directly, under the skull. A section of the skull is removed to allow the array to be fed in, then replaced. The result is near-identical to a high fidelity EEG that is under the skull and thus away from its pattern dampening properties.

In the Works: MEMS Brain-Computer Interface
Industry News

In 2008, Caltech researchers are working on developing a MEMS-based (Micro-Electro-Mechanical System) brain-computer interface, with initial designs proving promising, and holding the potential to overcome the signal degradation problem.

Large Image Display: The Stepford Wives: Merging Human and AI
This single frame taken from the 2004 film 'The Stepford Wives', shows the neuroprosthetic arrays used in The Stepford Wives, to control the brains of the wives. Obviously the placement here is wrong, to do what they do. Five ECoG ? electrocorticography ? arrays could not perform the functions of mind control demonstrated in the film, because they do not penetrate deeply into it. Thus they are symbolic of the science involved, rather than prescriptive.
