Mapping of Bayes' theorem on the cortico—basal—ganglia–thalamic circuit. A, Bayes' theorem in its original (top) and logarithmic (bottom) form. B, Mapping of Log of Bayes' equation on the subset of cortico—basal—ganglia–thalamic circuit. Black and light gray circles denote neuronal populations selective for two actions situated in different brain regions labeled next to the circles. Output, output nuclei of the basal ganglia; cortex,− frontoparietal cortical areas including neurons selective for actions. Arrows denote excitatory connections, while lines ended with circles denote inhibitory connections.
