In an effort to standardize SR assessment methods, we developed a machine learning algorithm and workflow to automatically classify SR waveforms in virtually any animal model including mice, rats, guinea pigs, and gerbils obtained with various paradigms and modalities from several laboratories. Absence of the Moro reflex in an infant is abnormal. The Moro reflex was first described by Ernst Moro in 1918 and is a primitive infantile reflex that causes an involuntary protective motor response. Next, the baby will move his/her tongue to the nipple to suck. Increased startle occurred in about one quarter of both stroke and spinal cord injury patients.
