1. 1 Purpose and Plan of This Review This review is focused on the topography and connections of some of the neuron populations that determine the manual dexterity of the macaque monkey. The populations selected for examination are the following: 1. The corticospinal neuron populations 2. The thalamocortical and corticothalamic neuron populations associated with the sensorimotor cortex 3. The ipsilateral cortical connections of the sensorimotor cortex These neuron populations have been chosen because of their obvious rel evance to the directed, intelligent use of the hands, but also because of their anatomical and functional interdependence. Corticospinal neuron populations transmit a complex, orchestrated output from a number of different regions of cerebral cortex to the neuron populations in every segment of the spinal cord, and this output includes the command information defining the intended manual action. The thalamocortical complex is especially concerned with the transmis sion and modulation or filtering of (a) visual, tactile, proprioceptive, vestibular, and auditory information to the cerebral cortex and (b) information from the cerebellum, basal ganglia, limbic system, and brain stem which is relevant to sensorimotor behavior. Finally, the extensive ipsilateral cortical connections constitute a major part of the supraspinal circuitry which coordinates the contri butions of all the cortical neuron popUlations contributing to intelligent sen sorimotor behavior and, in particular, transmits the cross talk between those cortical neuron populations which shape and control the dextrous handling of objects within reach.
The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world.Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.
This accessible book has a simple aim - to tell people what psychology is about. It presents a review of the key areas of the subject as it is traditionally taught, and provides the reader with an introduction to important concepts and findings within each of these. The reader should be able at least to make sense of most psychological topics.
Race, Law and Society draws together some of the very best writing on race and racism from the law and society tradition, yet it is not intended to merely reprint the greatest hits of the past. Instead, from its introduction to its selection of articles, this anthology is designed as a 'how-to manual', a guide for scholars and students seeking templates for their own work in this important but also tricky area. Race, Law and Society pulls together leading exemplars of the sorts of social science scholarship on race, society and law that will be essential to racial progress as the world begins to travel the twenty-first century.
One of the most famous shipwreck sagas of the 19th century took place on the tropical coast of north-east Australia. In 1836 the Stirling Castle was wrecked off the Queensland coast and many of the crew, together with the captain's wife, Eliza Fraser, were marooned on Fraser Island. Early sensationalized accounts represent Mrs Fraser as an innocent white victim of colonialism and her Aboriginal captors as barbarous savages. These "first contact" narratives of the white woman and her Aboriginal "captors" impacted significantly on England and the politics of Empire at an early stage in Australia's colonial history. The text critically examines the Eliza Fraser episode by bringing together an interdisciplinary team of authors, artists, members of the Fraser Island Aboriginal community and academics in the areas of cultural and women's studies, literature, history, anthropology, archaeology, the visual and creative arts. This book Essays include feminist analyses of the incident, investigations of textual and visual representations of Aboriginal people, and considerations of the role played by Elisa Fraser as creative inspiration for the arts. The text explores the constructions of Empire, colonialism, identity, femininity, savagery, otherness, captivity and survival.
Far away from any World War II battlefront, the citizens of Melbourne lived in fear of a serial killer - the Brownout Strangler. May 1942: Melbourne was torn between fearing Japanese invasion and revelling in the carnival atmosphere brought by the influx of 15,000 cashed-up American servicemen. But those US forces didn't guarantee safety. Not long after their arrival, the city would be gripped by panic when the body of a woman was found strangled, partially naked and brutally beaten. Six days later another woman was found dead and her body told the same horrific story. A murderer was stalking the streets. As women were warned not to travel alone, an intense manhunt ensued. Not long after a third woman was murdered, American soldier Eddie Leonski was arrested. A calculating psychopath, he had a twisted fascination with female voices, especially when they were singing . . . Acclaimed author Ian W. Shaw brings World War II Melbourne to life, and takes us into the mind of the Brownout Strangler, and a very different kind of terror. 'enthralling . . . makes for a fascinating read.'
