A mathematical model for the role of dopamine-D2 self-regulation in the production of ultradian rhythms
Fig 6
Behavioural activity output of the DUSR under circadian regulation.
Double-plotted activity defined as when DAex values exceed the previous day’s average, Eq (11). A: Behaviour activity for circadian signals of different waveforms and same amplitude. Red lines mark the peak circadian input and blue lines mark the trough. B: Behaviour activity output for increasing amplitudes of a symmetric sinusoidal circadian signal is increasingly refined within the subjective night.
