Brain-computer interface research comes of age: traditional assumptions meet emerging realities
Brain-computer interface research comes of age: traditional assumptions meet emerging realities.
J Mot Behav. 2010 Nov;42(6):351-3
Authors: Wolpaw JR
Brain-computer interfaces (BCIs) could provide important new communication and control options for people with severe motor disabilities. Most BCI research to date has been based on 4 assumptions that: (a) intended actions are fully represented in the cerebral cortex; (b) neuronal action potentials can provide the best picture of an intended action; (c) the best BCI is one that records action potentials and decodes them; and (d) ongoing mutual adaptation by the BCI user and the BCI system is not very important. In reality, none of these assumptions is presently defensible. Intended actions are the products of many areas, from the cortex to the spinal cord, and the contributions of each area change continually as the CNS adapts to optimize performance. BCIs must track and guide these adaptations if they are to achieve and maintain good performance. Furthermore, it is not yet clear which category of brain signals will prove most effective for BCI applications. In human studies to date, low-resolution electroencephalography-based BCIs perform as well as high-resolution cortical neuron-based BCIs. In sum, BCIs allow their users to develop new skills in which the users control brain signals rather than muscles. Thus, the central task of BCI research is to determine which brain signals users can best control, to maximize that control, and to translate it accurately and reliably into actions that accomplish the users' intentions.

Zilok: peer to peer renting
From Mauro Cherubini's Moleskine
Zilok is a startup that offers an interesting service: peer to peer renting.
How it works? Users post possessions they are willing to rent out, along with a price. The web site processes the fee, track the reputation of your renting partner and issues insurance for the item.

Metaverse Creativity
Intellect has announced the publication of the groundbreaking new journal Metaverse Creativity, which is the first refereed journal focusing on the examination of creativity in user-defined online virtual worlds such as Second Life.
While such creative activity includes artistic activity, this definition should in no way be limited to artistic output alone but should encompass the output of the various disciplines of design – such as fashion and object design, landscaping and virtual architecture – that are currently all amply manifest in Second Life.
Creativity in a metaverse manifests under unique conditions and parameters that are engendered by the virtual environment itself and it is intrinsically related to these in its very act of realization. Thus metaverse creativity cannot be separated from the underlying Metanomic system (metaverse economy), the legal issues of ownership and copyright, the very geography and related atmospheric/lighting conditions upon which the output is rendered, or the underlying computational system which generates this.
The inaugural issue includes a fascinating editorial by Elif Ayiter and Yacov Sharir.
