Interaction of brain devices

with one comment

Following up on recent developments in reading brainwaves, the issue of a common platform for these brain devices is currently being discussed. A highly readable article in Technology Review highlights the benefits of a common platform:

“These scientific issues can be disambiguated by rudimentary brain coprocessors, built with readily available off-the-shelf components, that use recording technologies to assess how a given neural circuit perturbation alters brain dynamics. Such explorations may begin to reveal principles governing how best to control a circuit–revealing the neural targets and control strategies that most efficaciously lead to a goal brain state or behavioral effect, and thus pointing the way to new therapeutic strategies.”

An argument not mentioned in the article, but raised by Mindhacks, is increased security. However, with current developments of army research in the field one might ask if one standard platform is a realistic thought if the plan is to actively lead brain activity from the outside.

It seems that in these systems built to alter brain activity, we will necessarily see two different developments: Outside control via usable devices like headsets that can easily be shared, changed and synced, and inside control via planted devices that can interact with other components but might not necessarily be built to be an open system sharing its data with others.  While the latter could thus be used to “control the nodes”, it is the former that can enhance the nodes in a collective brain and thus lead to a more intelligent approach towards collective intelligence sharing and cooperation.

  1. The synchronization protocol reduces the likelihood of malfunction arising from occasional spurious packets while also allowing for quick detection of complete channel loss and enabling smooth transitions between two redundant loops channels as needed. In one embodiment, the network is a ring network and the redundant loops are clockwise and counter-clockwise channels. The synchronization protocol also inherently tends to compensate for delays in signal propagation and processing, thereby minimizing or eliminating synchronization error. Tight synchronization between nodes (e.g., less than ± 100 ns) can thus be achieved. The synchronization period itself is selectable between 1 and 10 kHz. The dual ring network topology described herein can support synchronization and data exchange requirements for many parallel converters (e.g., 3 nodes, more than 3 nodes, or more than 8 nodes). There is zero control cycle latency for sharing of data between nodes: a data exchange rate of 1.25 Gb/s on a serial channel supports a 124 byte datagram from each node per exchange, and less than 50 is needed for a full exchange of data for an eight node system.
