Frontal cortex tracks surprise separately for different sensory modalities but engages a common inhibitory control mechanism
Fig 2
Single-subject example of surprise-term construction for each model.
Top: Model 1 uses separate surprise terms for each sensory domain. In effect, the presence of a surprising event in one sensory domain does not inform the prior in the other sensory domain. Bottom: Model 2 uses a combined surprise term across both domains. In effect, all unexpected events, regardless of domain, influence the construction of the prior.
