Abstract:
One of the interesting topics in neuroscience is problem solving and decision-making. In this area, everything gets more complicated when events occur sequentially. One of the practical methods for handling the complexity of brain function is to create an empirical model. Model Predictive Control (MPC) is known as a powerful mathematical-based tool often used in industrial environments. We proposed an MPC and its algorithm as a part of the functionalities of the brain to improve the performance of the decision-making process. It is well known that the decision-making process results from communication between the prefrontal cortex (working memory) and hippocampus (long-term memory). However, there are other regions of the brain that play essential roles in making decisions, but their exact mechanisms of action still are unknown. In this study, we modeled those mechanisms with MPC. We showed that MPC controls the stream of data between prefrontal cortex and hippocampus in a closed-loop system to correct actions.

Plain Language Summary
Decision-making is a cognitive process of the human brain. The brain behaves as a complex system, and providing a model would be a convenient way to represent the complexity of the brain. Every decision includes some stages: each stage can be interpreted as a cognitive criterion. The brain controls the path by predicting the action’s result. The brain needs to know the criteria to perform its primary function as a predictor. It is known that the hippocampus stores the knowledge, and the prefrontal cortex approximates the goals; therefore, our study models the interactions between the hippocampus and the prefrontal cortex by providing an algorithmic view. In our model, the effects of the brain regions controlling the path are replaced by the model predictive control. Now the neurological mechanisms of the decision-making process in the brain can be simulated. This capability supports memory consolidation theories and therapies of neurodegenerative diseases such as Parkinson.
