Effects of different light spectra on locomotion, anxiety, and heart rate in spontaneously hypertensive rats and Wistar-Kyoto rats.

ABSTRACT: Light exposure plays a critical role in regulating physiological and behavioral processes. This study aimed to explore how different light spectra influence locomotor activity, anxiety-like behavior, and heart rate variability in rodents. We used spontaneously hypertensive rats (SHRs), which exhibit distinct behavioral traits compared to normotensive Wistar-Kyoto (WKY) rats, as a model to examine strain-related differences in response to light conditions. Given known sex differences in behavioral phenotypes and light sensitivity, and the higher prevalence of certain behavioral traits in males, this study focused on male rats. Animals were exposed to white, blue, green, or red light-emitting diodes (LEDs), and their behavioral and physiological responses were assessed through locomotion tra
