Buonfiglio D, Hummer D, Armstrong A, Christopher Ehlen J, DeBruyne J
J Pineal Res . 2020 Sep; 69(4):e12697. PMID: 32976638
In 1965, Dr Harry Angelman reported a neurodevelopmental disorder affecting three unrelated children who had similar symptoms: brachycephaly, mental retardation, ataxia, seizures, protruding tongues, and remarkable paroxysms of laughter. Over...

Elliott Albers H, Walton J, Gamble K, McNeill 4th J, Hummer D
Front Neuroendocrinol . 2016 Nov; 44:35-82. PMID: 27894927
Virtually every neuron within the suprachiasmatic nucleus (SCN) communicates via GABAergic signaling. The extracellular levels of GABA within the SCN are determined by a complex interaction of synthesis and transport,...

Hummer D, Lee T
Neurosci Biobehav Rev . 2016 Jul; 70:171-181. PMID: 27450579
Adolescence is a time of tremendous adjustment and includes changes in cognition, emotion, independence, social environment, and physiology. One of the most consistent changes exhibited by human adolescents is a...

Hummer D, Ehlen J, Larkin 2nd T, McNeill 4th J, Pamplin 2nd J, Walker C, et al.
Eur J Neurosci . 2015 Apr; 42(2):1830-8. PMID: 25865743
The suprachiasmatic nucleus (SCN) contains a circadian clock that generates endogenous rhythmicity and entrains that rhythmicity with the day-night cycle. The neurochemical events that transduce photic input within the SCN...

Hummer D, Peckham E, Lee T
Eur J Neurosci . 2012 Jul; 36(8):3051-8. PMID: 22805184
The free-running circadian period is approximately 30 min shorter in adult male than in adult female Octodon degus. The sex difference emerges after puberty, resulting from a shortened free-running circadian...

Vosko A, Hagenauer M, Hummer D, Lee T
Am J Physiol Regul Integr Comp Physiol . 2008 Nov; 296(2):R353-61. PMID: 19036829
Recent data suggest that both nocturnal and diurnal mammals generate circadian rhythms using similarly phased feedback loops involving Period genes in the suprachiasmatic nuclei (SCN) of the hypothalamus. These molecular...

Hummer D, Jechura T, Mahoney M, Lee T
Am J Physiol Regul Integr Comp Physiol . 2006 Aug; 292(1):R586-97. PMID: 16917014
The slowly maturing, long-lived rodent Octodon degus (degu) provides a unique opportunity to examine the development of the circadian system during adolescence. These studies characterize entrained and free-running activity rhythms...

Lee T, Hummer D, Jechura T, Mahoney M
Ann N Y Acad Sci . 2004 Jul; 1021:262-75. PMID: 15251896
Unlabelled: The development of adult circadian function, particularly sexual dimorphism of function, has been well studied only in rapidly developed rodents. In such species development is complete by weaning. Data...
