Respiratory regulation & interactions with neuro-cognitive circuitry

Area of Science:

• Neuroscience
• Psychology
• Physiology

Background:

• Active breathing control, rooted in Vedic meditative practices, is recognized for its potential to alleviate stress, anxiety, and improve cognition.
• The neurophysiological mechanisms underlying respiratory modulation of brain function are an emerging area of research.
• Existing research suggests interplay between respiratory motor circuits, emotion/arousal centers, and sensory pathways like olfaction.

Purpose of the Study:

• To review evidence linking respiration, brain activity entrainment, and functional outcomes in mood and cognition.
• To explore the neurophysiological mechanisms through which breathing influences brain function.
• To discuss potential implications for neuropsychiatric disorders and biorhythm regulation.

Main Methods:

• Review of cross-species research findings.
• Analysis of studies on respiratory motor and sensory pathways.
• Exploration of links between respiratory and cardiac rhythms.

Main Results:

• Brainstem respiratory circuits modulate subcortical activity related to emotion and arousal.
• Sensory respiratory regions, such as the olfactory bulb, influence mood and cognition.
• Brain activity can be entrained to the respiratory cycle via both motor and sensory pathways.

Conclusions:

• Respiration profoundly influences neurophysiology, impacting mood and cognition.
• Understanding these links offers potential for therapeutic interventions in neuropsychiatric conditions.
• Further research into biorhythm regulation holds translational promise.
