“Network structure and dynamics involved in sleep-wake regulation”

Friday, November 9, 2012
from 4:00 p.m. to 5:00 p.m.
Science 145

It is well known that mammals and other animals cycle between periods of sleep and wakefulness. Sleep and wake states are each maintained by activity in a corresponding network of neurons in the brain, with mutually inhibitory connections between the networks. In infants, the durations of both sleep and wake states follow an exponential distribution, but in adults the wake states have a heavy-tailed distribution. Is it the altered network structure or a change in neuronal dynamics that drives this transformation during development? We use mathematical models and random graph theory to explore this issue and the mechanisms of transition between sleep and wake states.
