S3E4 - Sleep accross the lifespan - infants to old age

How does our sleep change as we age and what could this mean for memory and cognition?

In this episode, we discuss with Professor Rebecca Spencer her research exploring how our sleep patterns evolve over the course of our lives.

We explore the phenomenon of infantile amnesia - why we can't remember our earliest childhood experiences - and unpack the theories behind it. We discuss how hippocampal development changes as we age and how this links to memory consolidation and sleep. We also dive into Rebecca's work on emotional processing in children and how naps and sleeping are able to aid in emotional regulation.

Rebecca runs the Somneuro Lab at the University of Massachusetts Amherst. Find out more about Rebecca and her research group here.
