Babies sleep more per day during the first two years than any other point in life. Scientists agree that this is a period of rapid change in the brain and body – but the mystery remains, what function does sleep serve us so early in life?

One idea is that sleep is an opportunity for our brains to practice, and process — especially critical early in life, when we are experiencing so many new things in the world around us. The brain controls how we connect with each other, and form relationships with our peers and loved ones. Healthy physical connections with others, including a foundation called “social touch”, is formed early in life and requires proper sleep to fully develop.

Studies have found an association between poor sleep early in life and neurodevelopmental disorders characterized by differences in social connection. This talk will expand on this lingering mystery by exploring:

• How does the function of sleep change with age?
• How a unique rodent – the prairie vole – can teach us how sleep and snuggles help our brains develop the foundation of social touch.

Noah Milman is a graduate student in the Department of Behavioral Neuroscience at OHSU. Previously, he contributed to the first-in-human clinical trial of 40Hz sensory stimulation
for Alzheimer’s Disease. Now, he is interested in how early-life sleep and environment impact
the sensory brain and our social connections later in life.
