Digital EEG data were provided by Jeanne Townsend and Osamu Saitoh, working in the laboratory of Eric Courchesne. Thanks to Brian Egaas for teaching me everything I always wanted to know about signal processing but was afraid to ask, and ditto to Magnus Stensmo for discussions on network architecture and input representation. Thanks also to Terry Sejnowski and the Computational Neurobiology Laboratory at the Salk Institute for providing computing facilities and feedback. --MB
