Ultradian_pulse_generators

This MATLAB program is to generate time series and figures for a new mathematical model of a hormonal axis.
The model comprises two coupled ultradian pulse generators. One generator is located
in the hypothalamus, the second is located in the anterior pituitary.
Two integrate-and-fire schemes are used to describe the pulse generator mechanisms.
Depending on their firing thresholds and on the coupling gains, the system exhibits a variety of periodic or quasi-periodic behaviors.
