Abstract (not to exceed 200 words), for inclusion in conference announcments and the program: We have written a new textbook (O'Reilly & Munakata, 2000, "Cognitive Neuroscience: A Computational Exploration", MIT Press) that is centered around an extensive set of neural network simulation models covering a wide range of cognitive phenomena. These models are implemented in the PDP++ simulation environment developed by O'Reilly, Dawson, & McClelland. We will cover a range of these models in the tutorial, emphasizing the conceptual links between features of the underlying biology and cognitive phenomena using computational principles. 10. Abstract biography of presenter(s), (not to exceed 200 words total): Dr. O'Reilly has published papers on computational models of learning and memory in various brain areas (hippocampus, prefrontal cortex, and neocortex), and his dissertation was on a model of learning in the cortex motivated by computational, biological, and psychological considerations. He is interested in developing models of learning and memory that explain behavior in terms of the computational properties of their neurobiological substrates.

[invited] The PDP++ tutorial, while relatively new, is used to teach at the University of Colorado/Boulder, and will be presented by its author. This material will be published shortly by MIT Press.
