Subsequent sensory neurogenesis, differentiation occurs, and two varieties of nociceptors are shaped. These are classified as either peptidergic or nonpeptidergic nociceptors, each of which express a definite repertoire of ion channels and receptors. Their specializations enable the receptors to innervate diverse central and peripheral targets. This differentiation takes place in both of those perinatal and postnatal durations.
