ABSTRACT
The analyses of the OR so far in this book have employed a particular strategy-the so-called man-neuron-model approach. This includes studies at the microlevel and the macrolevel, attempting to integrate micro-and macrodata within a framework of a model uniting these phenomena. Later chapters examine orienting from the point of view of cognitive processes based on experiments with human subjects from a psychophysiological perspective. One of the main tools for studying brain functions are evoked and event-related potentials (ERPs), including brain-mapping and identification of dipoles that represent active neuronal populations under consideration. Some of the experiments to be reported, however, also use the more traditional autonomic somatic measures to assess orienting and anticipation.
