MORO
Moro, the startle reflex, is the more well-known of the defensive reflexes. Comprised of two integral parts, this reflex forms the foundation for our ability to mobilize to protect us from danger. The first stage involves a sudden response to stimuli that emerges in utero between 9-12 weeks. At once, the body moves out from the midline, flinging or stretching extremities while experiencing an uptick in adrenaline and an increased heart rate. The complimentary response, or second stage of Moro, is a return to calm or ‘cling.’ The outstretched limbs curl inward gradually, seeking embrace and soothing from a caregiver, while heart rate and breathing steady into a state of rest once again. Integrated within the first few months of infancy, the Moro reflex is an essential defensive reflex that leads us to develop self-regulation and a feeling of safety while navigating our environment.
