Salience, Values, and Decisions How does the brain make value-based decisions? There are two major competing models: goodsbased model action-based of value. Leathers Olson (p. 132 ) designed a critical experiment to decide between these views. In monkey brain, lateral intraparietal neurons responded strongly stimuli predicting both large rewards penalties, encoding salience stimulus rather than reward value, which refutes models.
