Exposure to Blue Wavelength Light Is Associated With Increases in Bidirectional Amygdala-DLPFC Connectivity at Rest
Source: Frontier in Neurology
DLPFC (Dorsolateral PFC)
Region in the prefrontal cortex of the brain that plays a vital role in:
- Executive functions
- Working memory
- Cognitive flexibility
- Planning, and
- Abstract reasoning
Amygdala
It serves as a central hub for:
- Emotion
- Memory
- Decision-making
- Social cognition
- Plays a key role in processing fear, aggression, and anxiety
- It triggers the flight, fight or freeze response
“Blue light exposure may positively influence mood by modulating greater information flow between the amygdala and the DLPFC,
…which may result in greater engagement of cognitive control strategies that are needed to perceive and regulate arousal and mood.”
“there is evidence to suggest that the amygdala receives direct projections from ipRGCs (see page 8) and that swift modulations of
…amygdala activation may contribute to the antidepressant effect of blue wavelength light”
