The Complexly Parcellated, Yet Quantitatively Reduced, Orexinergic/Hypocretinergic System of Humans
Journal of Comparative Neurology, Volume 533, Issue 2, February 2025.Immunohistochemical staining for orexin‐A reveals the novel parvocellular orexinergic neuronal cluster (left) in the human brain. In comparison to the more typically observed orexinergic neurons of the main cluster (right), the parvocellular neurons have much smaller soma. Scale bar = 100 µm, applies to both images.

Costs and benefits of allomaternal care to mothers and others in wild Phayre's leaf monkeys
American Journal of Biological Anthropology, Volume 185, Issue 3, November 2024.During the first month of life, Phayre's leaf monkey infants stayed with their mother (74%) or an unrelated allomother (immature or adult female). When infants were with an allomother (26%), mothers benefitted energetically by spending more time feeding. Although allomothers incurred costs by reducing feeding time, overall allomothering varied and most
