Information-Processing Channels in the Tactile Sensory System addresses the fundamental question of whether sensory channels, similar to those known to operate in vision and audition, also operate in the sense of touch. Based on the results of psychophysical and neurophysiological experimentation the authors make a powerful case that channels operate in the processing of mechanical stimulation of the highly sensitive glabrous skin of the hand. According to the multichannel model presented in this monograph, each channel, with its specific type of mechanoreceptor and afferent nerve fiber, responds optiimally to particular aspects of the tactile stimulus. It is further proposed that the tactile perception of objects results from the combined activity of the individual tactile channels. This work is important because it provides researchers and students in the field of sensory neuroscience with a comprehensive model that enhances our understanding of tactile perception.

The Antarctic is the last vast terrestrial frontier. Just over a century ago, no one had ever seen the South Pole. Today odd machines and adventure skiers from many nations converge there every summer, arriving from numerous starting points on the Antarctic coast and returning some other way. But not until very recently has anyone completed a roundtrip from McMurdo Station, the U.S. support hub on the continental coast. The last man to try that perished in 1912. The valuable surface route from McMurdo remained elusive until John H. Wright and his crew finished the job in 2006.Blazing Ice is the story of the team of Americans who forged a thousand-mile transcontinental "haul route" across Antarctica. For decades airplanes from McMurdo Station supplied the South Pole. A safe and repeatable surface haul route would have been cheaper and more environmentally benign than airlift, but the technology was not available until 2000.As Wright reveals in this gripping narrative, the hazards of Antarctic terrain and weather were as daunting for twenty-first century pioneers as they were for Norway's Roald Amundsen and England's Robert Falcon Scott when they raced to be first to the South Pole in 1911–1912. Wright and his team faced deadly hidden crevasses, vast snow swamps, the Transantarctic Mountains, badlands of weird wind sculpted ice, and the high Polar Plateau.Blazing Ice will appeal to Antarctic aficionados, conservationists, field scientists, and adventure readers of all stripes.
