<p>The case for the 22-h T cycle is shown for VL (<b>A</b>) and DM (<b>B</b>), and the case for the 26-h T cycle is shown for VL (<b>C</b>) and DM (<b>D</b>). The coupling strengths are identical for all the oscillators (i.e., η = 0). Entrainment of the sub-network to the 22-h cycle is represented by the yellow region, and entrainment of the sub-network to the 26-h cycle is represented by the blue region.</p
