A randomized placebo-controlled trial with behavioral, neuroimaging, and physiological measures reveals that oxytocin treatment facilitates pleasure and brain reward responses only to gentle stroking social touch by increasing peripheral blood concentrations.

Single measurements of baseline salivary and plasmatic oxytocin are not sufficiently reliable to provide valid trait markers of the physiology of the oxytocin system in humans.

Assessments using chemogenetic and pharmacological approaches reveal that modulation of the activities of oxytocin neurons in the hypothalamus of the central nervous system could inhibit colorectal cancer progression in mice.

Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).

Starfish feed by everting their stomach out of their mouth over prey and, interestingly, this unusual feeding mechanism is inhibited by substances similar to hormones that regulate feeding in humans.

The most comprehensive neuroanatomical atlas on the expression of three glycoprotein hormone receptors, namely, TSHRs, LHCGRs, and FSHRs, was mapped using RNAscope, a technology that allows the detection of mRNA at single-transcript level.

A new ethologically relevant model for investigating the neurobiology of solitary, asocial behavior in the blind mole rat.

Zdbf2 is a paternally expressed gene that is mainly expressed in the hypothalamus and promotes appetite and body weight gain in neonates.

AGRP neurons integrate environmental food-related cues with internal metabolic signals to modulate interscapular brown adipose tissue thermogenesis and energy expenditure, at least in part, via mTORC1 signalling.
