Erik Herzog is a chronobiologist and neuroscientist who studies the molecules, cells and circuits that underlie daily rhythms in physiology and behavior. He has discovered a wide array of the mechanisms underlying how circadian clocks regulate physiology, behavior and health.
Herzog’s research is focused on: determining how neurons release neuropeptides that synchronize circadian cells; testing the role of maternal and fetal circadian tissues in timing birth; establishing the ionic basis for daily rhythms in neuronal excitability; and mapping the connections and cell types that underlie daily rhythms as a function of age, sex and the seasons.
Herzog serves as the president of the Society for Research on Biological Rhythms and the director of the St. Louis Neuroscience Pipeline, a National Institutes of Health-funded initiative to increase diversity in the neurosciences.
By activating a small subset of the neurons involved in setting daily rhythms, biologist Erik Herzog in Arts & Sciences has unlocked a cure for jet lag in mice, as reported in a July 12 advance online publication of Neuron.
Star-shaped cells called astrocytes, long considered boring, “support cells,” are finally coming into their own. To everyone’s surprise they even play an important role in the body’s master clock, which schedules everything from the release of hormones to the onset of sleepiness.
Fireflies use oscillation to communicate on the same wavelength. An engineer at Washington University in St. Louis has developed a new waveform that can control chemical oscillation in the lab. This finding could lead to better understanding of oscillation as it pertains to heart pacemakers, the brain’s neural patterns and even jet lag.
People often feel draggy the day after they have to set
their clocks forward in the spring but often shrug off that feeling as
trivial. In fact, says Erik Herzog, PhD, a neuroscientist at Washington
University in St. Louis, who studies biological clocks, jamming our
biological clocks into reverse, as daylight savings time does, has
