The genetics of morning larks: Louis Ptacek

LouisPtacek
In this week’s episode, Dr. Louis Ptacek, an investigator for the Howard Hughes Medical Institute and a professor at the University of California - San Francisco, discusses how alterations in our genes (called “mutations”) are responsible for why "morning larks" have to wake up in the middle of the night.

Louis is interested in understanding certain aspects of normal brain function, such as sleep. In my chat with him, he talks about our body’s natural circadian rhythm and how it is controlled by a “feedback loop” that controls gene expression and protein construction.

  1. I will probably wait for the results of this research. I sometimes find myself awake in the middle of the night and unable to sleep. Wonder what causes this.
