Marine Mammal Sleep Studies in Russia
THE ROLE OF SLEEP IN COGNITIVE PERFORMANCE
I trained a wild fur seal to perform shape recognition tasks, which she performed before and after a short period of sleep deprivation.
We trained another fur seal to do noise discrimination tasks. After a short period of sleep deprivation, his performance was measured again.
Surprisingly, there was usually a slight increase in acuity and performance after exposure to this type of stress.
THE EFFECT OF UNDERWATER NOISE ON BELUGA ENDOCRINE & RESPIRATORY SYSTEMS
We tested the beluga's sensitivity to underwater noise by measuring blood cortisol levels, heart rate, and breathing rate during exposure to seismic noise.
The subject of anthropogenic noise is an area of growing concern within the field of marine mammal dive physiology, due to the sonar-related mass strandings of beaked whales.
EYE STATE AND UNIHEMISPHERIC SLEEP IN THE NORTHERN FUR SEAL
Advisor: Oleg Lyamin (PhD), Center for Sleep Research, UCLA School of Medicine
I spent two months in Russia studying sleep in marine mammals, including northern fur seals and beluga whales.
For my honors thesis, I focused on the correlation between eye state and sleep state, scored using both qualitative (visual scoring) and quantitative (scoring based on spectral power analysis) electroencephalogram (EEG) data.
