This implements a model of Locus Coeruleus / Norepinephrine (LC/NE) function described in Gilzenrat et al. (2002), used to simulate behavioral and electrophysiological data (from LC recordings) in non-human primates.
The plots below were generated by PsyNeuLink (left) and the original MATLAB code used by Gilzenrat et al. (right). For a clearer comparison, we've plotted the target unit, distraction unit, and response unit outputs as well as the h(v) and u values produced by the LC in each figure, all without noise.
Similar plots with noise were included in the original Gilzenrat et al. (2002) paper in figures 4A and 5A.
The FitzHughNagumoIntegrator <FitzHughNagumoIntegrator> function documentation includes details on how to tailor the PsyNeuLink FitzHughNagumo implementation to the equations (6, 7, and 8) in Gilzenrat et al. 2002.
