Abstract

Stretch reflex circuits are a prime example of wiring specificity in the vertebrate spinal cord. Homonymous sensory afferents and motoneurons typically form monosynaptic connections, while neurons innervating antagonistic or unrelated muscles do not. Pecho-Vrieseling et al. now show that the semaphorin Sema3E and its receptor Plexin-D1 prevent monosynaptic connectivity in the cutaneous maximus muscle stretch reflex circuit.
