We've gathered the NaPS lab to answer all your fascinating questions on all things sleep! A perfect bitesize episode to get stuck into the marvellous world of sleep. 1. How does sleep deprivation affect mental health? - Answered by Martha Wawrzuta Bunney, B. G. , Bunney, W. E. (2013). Mechanisms of Rapid Antidepressant Effects of Sleep Deprivation Therapy: Clock Genes and Circadian Rhythms. Biological PsychiatryFang, H., Tu, S., Sheng, J., Shao, A. (2018). Depression in sleep distu...
In this episode, we welcome neuroscientist Michele Bellesi from the University of Camerino to explore the fascinating world of glial cells and their dynamic role in sleep. Michele guides us through the four types of glial cells: Astrocytes: Regulators of synaptic function and help form the blood brain barrier (BBB)Oligodendrocytes: Crucial for myelination and fast signal transmissionMicroglia: The brain's immune sentinels, important for responding to infection and injury as well as shap...
Can sleep help us unlearn biases and make our memories more positive? Implicit biases are unconscious stereotypes that influence our judgments and decisions - like assuming a particular gender for a specific job role. But what if we could change these biases? In this episode, we explore how manipulations of sleep might help reshape our implicit attitudes. We speak with Professor Xiaoqing Hu, a leading researcher in the use of Targeted Memory Reactivation (TMR) during sleep to alter implicit b...
We're joined by Hongi Ngo, who developed a revolutionary technique for manipulating sleep oscillations during his PhD. Closed-loop Auditory Stimulation (CLAS), which uses bursts of pink noise which are carefully timed to a particular phase of an existing brain oscillation to either boost or dampen the target oscillation. It has been used to selectively strengthen or weaken memories, improve the immune response, reduce epileptic seizures, and even potentially to slow down age relat...
How are memories represented in the brain and how can we model this? Professor Anna Schapiro from University of Pennsylvania as we discuss her work on computational modelling of sleep and memory. In this episode, we discuss several kinds of Neural Network models as well as diving into the history of Jay McClleland's Complementary Learning Systems theory and Anna's recent work on combining neural network modeling with EEG. Find out more about Anna Schapiro and her research group here. Li...
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...
In this deep dive episode, we look at how sleep onset can help creativity. With our amazing guest speakers, Professor Bob Stickgold, Dr Adam Horowitz, Professor Delphine Oudiette and Dr Celia Lacaux, we take a look at their work on creativity, dreams and N1 sleep. Together, we discuss different definitions of creativity, what defines N1 and what it is about N1 that makes it prime time for creative processing. Find out more about our guest speakers: Professor Bob StickgoldDr ...
Sleepwalking, sleep talking, night terrors - how do they occur and why do some people have them more than others? Join us as we discuss with Professor Francesca Siclari her work looking at non-REM parasomnias and the link to dreaming. We discuss the various forms that non-REM parasomnias can take, how they differ between adults and children and what the potential consequences of them can be. Find out more about Francesca and her research group here. Here are links to some of the stud...

We spend a third of our lives sleeping, and this podcast is all about understanding sleep. We know a lot about what the brain does in sleep, but we are just starting to understand why it does some of these things, and even more excitingly, how we can take full advantage of sleep and also manipulate it for our own ends. In each episode, neuroscientist Penny Lewis interviews a different sleep researcher, talking about a various aspect of sleep science. Topics include sleep physiology and medicine, circadian rhythm, how sleep impacts on our memories and creativity, Sleep Engineering for enhanced health and cognition, and the most recent technologies to promote sleep.©SleepSciencePodcast 2021.
