DESCRIPTION:Dynamics and bifurcations of sleep-wake behavior\n\nVictoria Bo
 oth\, University of Michigan\n	Tuesday March 16\, 12-1pm\n	Zoom Link: https:

 ake states are regulated by the interactions among a number of brainstem a
 nd hypothalamic neuronal populations and the expression of their neurotran
 smitters. The timing of these transitions is strongly modulated by the 24 
 h circadian rhythm and the homeostatic sleep drive\, the irresistible urge
  for sleep after being awake. We have been developing and analyzing mathem
 atical models of sleep-wake regulatory networks to understand how the inte
 raction of these processes dictate the timing and durations of sleep and w
 ake episodes. To investigate model dynamics related to the circadian modul
 ation of sleep patterns\, we have reduced the dynamics of sleep-wake regul
 atory network models to a one-dimensional circle map\, a classic technique
  for analyzing coupled oscillator systems. The sleep-onset maps\, which tr
 ack the phase of the circadian rhythm at which sleep onset occurs on succe
 ssive days\, have interesting properties such as non-monotonicity and disc
 ontinuities. In this talk\, I’ll discuss how the properties of these maps 
 reflect and influence sleep-wake patterns and their bifurcations.\n
