Neurobiology of Sleep[login at prompt]
Available: 07/01/19, Expires: 07/01/21

The Scammell Lab focuses on understanding the neurobiology of sleep. We spend much of our lives asleep, and yet surprisingly little is known about why we sleep and how the brain controls sleep. These are important questions because sleep disorders affect about ¼ of the population, resulting in problematic sleepiness, troublesome behavior during sleep, and miserable sleepless nights. Much of the work in our lab focuses on Narcolepsy, a common cause of chronic sleepiness that is caused by the selective loss of hypothalamic neurons producing the orexin/hypocretin neuropeptides.

Possible student projects include:
1) Using anatomic and physiologic techniques to map out the neural circuits through which the orexin peptides control wakefulness and regulate REM sleep.
2) Determining how cholinergic neurons in the pons promote arousal.
3) Examining how pain disrupts sleep and why poor sleep worsens pain.
4) Mapping the circuits through which positive emotions trigger cataplexy (brief episodes of paralysis) in narcoleptic mice.

Many projects in the lab use mouse models to understand the function of circuits that control sleep and wakefulness. We use cutting edge physiologic and molecular biologic techniques such as optogenetics, fiber photometry, Cre-loxP recombination, construction of new recombinant mice, and tracing of anatomic pathways using conditional expression of fluorescent proteins. We also work with post-mortem human brain tissue to better understand how loss of wake-promoting neurons with traumatic brain injury produces chronic sleepiness in humans.

Narcolepsy is a common sleep disorder caused by loss of the orexin-producing neurons in the hypothalamus. The student will perform basic science research using mouse models of narcolepsy to identify the brain circuits that give rise to sleepiness and cataplexy. Techniques may include fiber photometry to track neuronal activity and levels of neurotransmitters, optogenetics, chemogenetics, sleep recordings in mice, and anatomic studies. Prior experience in basic animal research is helpful but not necessary. The mentor (Dr. Scammell) has an office next to the lab in the Center for Life Sciences and will meet with the student at least weekly.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication.
