Article Synopsis
- Aberrant light/dark cycles from electric light usage can disrupt circadian rhythms, leading to mood disorders, but research on physiological effects is limited.
- An experiment on male Wistar rats showed that long light phases (20L:4D) led to decreased body temperature and activity rhythms, while long dark phases (4L:20D) caused circadian misalignment, both resulting in increased body weight.
- Changes in neurotransmitter levels were observed in specific brain areas, and both extreme light/dark cycles caused anxiety-like behaviors in the rats, indicating that these cycles can negatively impact mood and behavior.
Brain monoaminergic neurotransmitters, such as dopamine (DA), serotonin (5-HT), and noradrenaline (NA), play crucial roles in neuronal and physiological functions, including social behaviors. Isolation housing may induce behavioral and neurochemical abnormalities in rats, although its influence on neurotransmitter levels remains obscure. This study investigated the influence of isolation- or group-housing on core body temperature (T ), locomotor activity (ACT), emotional behavior, and neurotransmitter levels in male Wistar rats.
