Figure 5. Population novelty signal across areas.

Average novelty signal, computed as a neuron’s response to a stimulus as a standard subtracted from its response as a deviant (DEV-STD). Average magnitude of novelty signal is shown separately for each stimulus and area, error bars are SEM. All areas show a population-based novelty signal, but only auditory cortex shows a signal whose magnitude is affected by driving stimulus (sig difference denoted as a star).
