Dopamine-signalled reward predictions generated by competitive excitation and inhibition in a spiking neural network model
Dopaminergic neurons in the mammalian substantia nigra displaycharacteristic phasic responses to stimuli which reliably predict thereceipt of primary rewards. These responses have been suggested toencode reward prediction-errors similar to those used in reinforcementlearning. Here, we propose a mod...
