In this paper we study how decisions can be affected by varying frequencies and magnitudes of a perceptual stimulus in a simulated binary choice task. As a result we find that reaction time distributions may resemble the periodicity of the external stimulus. The article is fully open access.

This paper studies a model animal choosing between different food sources in an ongoing decision-making process. The decision-making circuit regulating the response is implemented via a generic neural hardware motif. Nonlinearities in the circuit influence the behaviour of the model animal. We find the unexpected result that inherent oscillations of neuronal activity may enhance decision-making performance.
