Fig. 6: Uni- and bi-directional variants of the winning model in the value task.
From: Modality-specific and modality-general representations of subjective value in frontal cortex
A Model space consisting of all possible unidirectional variants of the winning model in the value task (i.e., U1, also refer to the legend of Fig. 5A and the schema in Fig. 5C for information on nodes and modulatory connections). B Exceedance probabilities for the model space in A. Model U1, i.e., a model containing bidirectional connections between all nodes, is the most likely model (ROIs: V – Valuation region, S – Sensory region, purple V – vmPFC, red V – Auditory OFC, blue V – Visual OFC, red S – Auditory Sensory Cortex, blue S – Visual Sensory Cortex). The second best model is U3, which only contained feedback connections between the OFC nodes (red and blue V) and sensory cortices (red and blue S).
