My colleagues and I have pioneered and developed a number of the fundamental principles, mechanisms, and architectures that form the foundation for contemporary neural network research, particularly those which enable individuals to adapt successfully in real-time to unexpected environmental changes. Such models have been used both to analyse and predict interdisciplinary data about mind and brain, and to suggest novel architectures for technological applications. Current research ranges from perception through cognition and cognitive-emotional interactions to sensory-motor planning and control, in both normal individuals and mental patients. Recent models quantitatively link the neurophysiologically recorded dynamics of neurons, in anatomically validated networks, to the behaviors that their interactions control. Applications are made as spinoffs of these novel biological designs.
