The other, Scientific American:
I believe Wired magazine also recently had an issue devoted to BCIs.
From the WSJ piece:
What does all of this amount to? The start of a revolution. Scientists are beginning to unravel the question of how our material brains form our intangible minds. Though primarily motivated by medical and therapeutic goals, this research may have the greatest practical impact in areas such as product marketing, computer interfaces and criminal justice. Ultimately, it may help to answer fundamental questions about consciousness and free will, or even lead the way to preserving the knowledge and memories of individuals long after their bodies have failed.
Remarkable as these results are, they are likely to pale in comparison to what may be on the horizon with new or improved tools. Emerging techniques, such as functional near-infrared spectroscopy (fNIRS), may substantially expand potential uses. Human tissue, including bone, is largely transparent to infrared light, at least to a depth of a few centimeters. By shining infrared light into your skull and measuring the amount reflected, researchers are able to quantify changes in blood flow.
This technique has several advantages over fMRI: It’s faster, cheaper and more portable, so subjects’ brains can be measured while they are engaged in common activities like exercising, interacting with other people and playing games.
And, soon, there will be FNIRS devices that scan at depth and with greater temporal and spatial resolution than FMRI.
