Brain-computer interfacing is an area of research that is currently in flux as researchers try to understand not only what but who BCIs will work best for. One study by a group of researchers at Bremen University, Germany has recently attempted to determine who, exactly, is the key demographic for BCI use. More specifically, they looked at a group of subjects using a certain flavor of EEG-based BCI called steady state visually evoked potential (SSVEP), a technique where visual stimuli are flashed on a screen at certain frequencies. These flashes have very nice EEG signals for increasing classification accuracy during a certain visual task. Read the rest of this entry »

Patrick Cox is the author of a very interesting article on Contrarianprofits.com. In the post, Cox makes the case that the time is ripe for large-scale adoption of robotics in both civilian and military applications.The latter is old news: in previous posts, we looked at the growing opportunities, and concerns, of robotic applications in dangerous (or dangerously boring) domains.

In About SyNAPSE I characterized neuromorphic devices as the opposite of conventional Von Neumann processors. This is somewhat of a oversimplification, however. Modern processors are actually quite evolved from pure Von Neumann devices. They are dramatically more capable on virtually every computational workload than their heritage would suggest is possible. For neuromorphic devices to find any success in the marketplace, they’ll need to offer a significant performance gain against existing solutions, but with comparable or lesser power consumption and cost.

Top Gun taught us that the best and brightest pilots can perform some amazing aerobatics.  Nobody seems surprised that a good pilot, with some practice, can move seamlessly from the flight maneuvers used on a Boeing 747 to those featured in Blue Angels shows.  While computer autopilots have performed well in commercial aircraft for some time, however, getting an electronic computer to pull a plane successfully through an aerobatic maneuver is almost impossible, and is thus a relatively new field of research.

One of the major themes in the SyNAPSE project is developing chips that can learn meaningful information, and preserve it over time. In other words: memristors can learn, but we need to ensure that they are stably learning something useful for the system they are embedded in.

Some help to solve this technological problem comes from neuroscience. The question of how can the cerebral cortex develop stable memories while at the same time incorporating new information through an organism lifetime has been a central theme in many research groups. The talk posted on Neurdon describes one of these approaches. Read the rest of this entry »
