A circuit of evaluation and selection of the alternatives is considered a reliable model in neurobiology.
The prominent contributions of the literature to this topic are reported.
In this study, valuation and choice of a decisional process during Two-Alternative Forced-Choice (TAFC) task are represented as a two-layered network of computational cells, where information accrual and processing progress in nonlinear diffusion dynamics.
The evolution of the response-to-stimulus map is thus modeled by two linked diffusive modules (2LDM) representing the neuronal populations involved in the valuation-and-decision circuit of decision making.
Diffusion models are naturally appropriate for describing accumulation of evidence over the time.
This allows the computation of the response times (RTs) in valuation and choice, under the hypothesis of ex-Wald distribution.
A nonlinear transfer function integrates the activities of the two layers.
The input-output map based on the infomax principle makes the 2LDM consistent with the reinforcement learning approach.
Results from simulated likelihood time series indicate that 2LDM may account for the activity-dependent modulatory component of effective connectivity between the neuronal populations.
Rhythmic fluctuations of the estimate gain functions in the delta-beta bands also support the compatibility of 2LDM with the neurobiology of DM.
