Except for variable depression in the first few minutes, reflex responses were not reduced or otherwise significantly affected by transection in the hour immediately following the lesion or for at least 50 h. The results suggest that reduction in muscle spindle sensitivity and/or in polysynaptic motoneuron excitation contributes to stretch reflex depression after cord transection.10amonosynaptic reflex10aprimate10aSpinal Cord10aspinal cord injury10aspinal reflex10aspinal shock1 aWolpaw, Jonathan1 aLee, C., L.  uhttp://www.ncbi.nlm.nih.gov/pubmed/3480233
