Abstract
Daily activity patterns of male and female Nile grass rats were tracked under varied lighting conditions for several weeks.
- Circadian rhythms are linked to cognitive functions, which may be disrupted in mood disorders like Seasonal Affective Disorder (SAD) and Major Depressive Disorder (MDD).
- Alterations in daily light patterns could induce or worsen neuropsychiatric diseases.
- Bright-light therapy, aligned with circadian timing, may provide treatment options for mood and behavioral issues.
- The Nile grass rat's diurnal nature offers a distinct model for studying light modulation effects that may be relevant to humans.
- The study identified sex-specific circadian patterns and responses in grass rats, laying groundwork for future research on light's impact on mood-related brain circuits.
