A mathematical and biological plausible model of decision-execution regulation in “Go/No-Go” tasks: Focusing on the fronto-striatal-thalamic pathway

Discovering factors influencing the speed and accuracy of responses in tasks such as “Go/No-Go” is one of issues which have been raised in neurocognitive studies. Mathematical models are considered as tools to identify and to study decision making procedure from different aspects. In this paper, a mathematical model has been presented to show several factors can alter the output of decision making procedure before execution in a “Go/No-Go” task.The dynamic of this model has two stable fixed points, each of them corresponds to the “Press” and “Not-press” responses.
