Topic: salience signal

Learning the predictive relationships between stimuli and rewards is critical for adaptive behaviour. Non-human animal studies suggest that reward learning is driven by dopaminergic midbrain responses which evolve in time from a salience signal to a valuation signal (Schultz, 2016). These two signals are believed to emerge from the same population of midbrain neurons and as such are mixed into an aggregate signal that is difficult to decouple, even at the level of single-neuron recordings. Here we exploit high-temporal precision electrophysiology (EEG) collected simultaneously with 7T function
