Your heart may race, you may sweat, you may breathe faster, your muscles may tense (to the point you might even jump), and you may feel scared.

The major form of hyperekplexia is characterised by excessive startle reflexes, startle-induced falls, and continuous stiffness in the neonatal period. This reflex is referred to as the Moro reflex, or startle reflex. Moro reflex is often called a startle reflex, is a type of involuntary (without trying) response to stimulation where a baby throws back his or her head, extends out the arms and legs, cries, then pulls the arms and legs back in when a baby is startled by a loud sound or movement.

The startle reflex is a posture of pain. Participants included healthy young adults (YA), healthy older adults (OA), and individuals in the early stages of Alzheimer's disease (AD). (FFRs) were measured in normal hearing young adults, they observed that frequency differences of two-tone stimuli, which were able to evoke FFRs, were smaller than the behavioral FDL threshold (Xu and Gong, 2014). The grocery store can feel dangerous. Finally, there's the perspective of possible clinical applications. The study will test a new mobile application "app" that can be run on an iPhone10. When exhibiting the Moro response they will flex and thrust out their arms, hands, and legs, show a startled expression, and possibly cry. action tendencies.
