Artificial light at night affects brain plasticity and melatonin in birds
Artificial light at night changes brain flexibility and melatonin levels in birds
AI simplified
Abstract
ALAN significantly increased cell proliferation in the ventricular zone of zebra finches.
- Exposure to artificial light at night may impair neuronal densities in two brain regions, indicating potential neuronal death.
- Nocturnal melatonin production was suppressed in a dose-dependent manner by artificial light at night.
- Increased body mass could be associated with exposure to artificial light at night.
- Disruption of the circadian cycle in birds may have similar negative effects on cognitive functions as observed in mammals.
