(MAtmvmuLwmJ W Our primary experimental approach has been to record from single neurons in awake, behaving animals in order to determine the loci of neurons with condi-tioning-related activity and to quantitate the relationship. of this activity to the expression of the conditioned response. Our theoretical approach has been to extend simple computational models of connectionist learning into physiologically plausible neural networks that describe real-time features of conditioned behavior. These network models, and their possible implementations in the brain, suggest experimental tests and provide direction for physiological studies
