A hallmark of cognitive control is the ability to make decisions quickly and accurately, drawing from external information or endogenous factors. When information, reward, risk or cost is not evaluated optimally, it can result in subpar or inefficient decision-making, often seen in various neurological disorders. This talk will explore the application of bounded stochastic processes as a cognitive model of decision-making. Through analytical solutions and numerical simulations, this family of models offers insights into how decision deficits and strategic alterations manifest through changes in its key parameters, shedding light on the mechanisms underlying suboptimal decision-making. Furthermore, we will discuss the use of a simplified model to analyse multimodal brain imaging data (functional MRI, diffusion MRI and EEG), dissecting and localizing the neurocognitive processes underlying human decision-making.
