Tactile recognition in sheep. Tactile cues include licking the newborn, particularly during the first hour of life. By starting at the head, nose, ears, and the anogenital region, the mother encourages the offspring to stand up and consume colostrum. The endocrine response in lambs activates zones in the LC, AMY, and BNST, where an increase in noradrenergic neurons, adrenergic, oxytocin or V1a receptors occurs. AMY, amygdala; LC, locus coeruleus; NE, norepinephrine; V1a, vasopressin 1a.
