Ethiopian Love Song
In 1972, as a “defrocked” debutante, I worked at a mission hospital in Haiti. It was a summer like no other: full of life, death, and love in unexpected guises. In short, the trip was transformative, drawing me to new worlds like a moth to a flame. Before long, I decided to study tropical medicine. A decade later—as an infectious diseases trainee—my Chief took me aside. “Can you speak with an a...
متن کاملCircadian rhythm mutations in Drosophila melanogaster affect short-term fluctuations in the male's courtship song.
Courtship song in Drosophila is produced by the male's wing vibration and consists of pulses of tone produced at intervals of approximately 34 msec in D. melanogaster and 48 msec in D. simulans. We have observed that the intervals between these pulses are not constant but fluctuate rhythmically with periods of approximately 1 min in D. melanogaster and 0.5 min in D. simulans. In D. melanogaster...
متن کاملAn arousing, musically enhanced bird song stimulus mediates circadian rhythm phase advances in dim light.
A musically enhanced bird song stimulus presented in the early subjective night phase delays human circadian rhythms. This study determined the phase-shifting effects of the same stimulus in the early subjective day. Eleven subjects (ages 18-63 yr; mean +/- SD: 28.0 +/- 16.6 yr) completed two 4-day laboratory sessions in constant dim light (<20 lux). They received two consecutive presentations ...
متن کاملCircadian Rhythm, Exercise, and Heart.
Circadian rhythm is an evolutionarily conserved mechanism from archaea to human. To deal with the day-night changes in the environment on earth, circadian rhythm modulates the biological function to coordinate an appropriate timing for each process. Circadian rhythm and exercise have important impacts on each other. Exercise is a strong entrainment signal for mammalian circadian clock. 1 Proper...
متن کامل“Bird Song Metronomics”: Isochronous Organization of Zebra Finch Song Rhythm
The human capacity for speech and vocal music depends on vocal imitation. Songbirds, in contrast to non-human primates, share this vocal production learning with humans. The process through which birds and humans learn many of their vocalizations as well as the underlying neural system exhibit a number of striking parallels and have been widely researched. In contrast, rhythm, a key feature of ...
