Motion processing picks up speed in the brain

Lipid research picks up speed on the slopes of Taos.

The 2002 Keystone Symposium on "Regulation of Cellular Responses by Lipid Mediators" provided a lively and active forum to discuss research in lipid signaling. This meeting review can provide only a glimpse into the diversity of research presented. Here we have chosen to highlight a group of exciting presentations describing novel features of the temporal and spatial regulation of phosphoinosit...

Processing speed in the motion-induction effect.

The motion-induction effect, where an illusory motion is perceived within a bar when it is shown next to a spot presented slightly earlier, was studied with respect to the idea that it is based on differential processing speeds between the two ends of the bar. First, by using just a bar with a luminance gradient, the existence of a motion illusion (gradient motion) within such a bar was demonst...

Measuring the Attentional Speed-up in the Motion Induction Effect

Motion induction is the illusory motion within an elongated stimulus, such as a bar or a line, when it is preceded by a priming stimulus next to one of its ends. Motion is away from this primer. The presentation of two priming spots at both ends of a stimulus bar results in motion away from both spots with a collision in the center of the bar. With a sufficiently long delay between the spots, m...

High Speed Motion Estimation Using Stream Processing

Media processing applications are dominant in many new workloads today. These applications including 3D graphics, image compression, and signal processing, require tens to hundreds of billions of computations per second. To achieve real-time requirements, current media processors use special purpose architectures. Because of the changes in media applications and standards, flexibility is an imp...
