From: Flexible gating between subspaces in a neural network model of internally guided task switching
Different components of the model can be mapped to different brain regions; The conjunctive error x rule neurons may reside in the anterior cingulate cortex; The rule neurons may be found in the dorsal-lateral PFC; The input to the PFC module about negative feedback may come from subcortical areas such as the amygdala or the midbrain dopamine neurons; The sensorimotor module may correspond to parietal cortex or basal ganglia which have been shown to be involved in sensorimotor transformations; Neurons in the input layer that encode the color and shape of the card stimuli exist in higher visual areas such as the inferotemporal cortex; Neurons in the output layer that encode different response locations could correspond to neurons in the motor cortex.
