This paper is the 28th consecutive installment of the annual review of research concerning
the endogenous opioid system, now spanning over a quarter-century of research. It …

Appetite is controlled by a complex system of central and peripheral signals interacting to
modulate the ingestion response. Several brain mediators with complex networks adjust …

Feeding is an essential behavior for animals to sustain their lives. Over the past several
decades, many neuropeptides that regulate feeding behavior have been identified in …

This review is part of a special issue dedicated to Opioid addiction, and examines the
influential role of opioid peptides, opioid receptors and opiate drugs in mediating food intake …

Intracerebroventricular injection of visfatin caused increased feed intake and pecking
efficiency, but did not affect water intake in chicks. Visfatin-treated chicks had increased c …

The present study was designed to examine the effects of intracerebroventricular injection of
para-chlorophenylalanine (PCPA)(cerebral serotonin depletive), fluoxetine (selective …

Nociceptin/orphanin FQ (N/OFQ) and gamma aminobutyric acid (GABA) agonists have been
shown to increase feed intake in mammals and birds. In this study, the effect of …

The aim of the current study was to determine the effects of the central dopaminergic system
on N/OFQ-induced feed intake in 3-h feed-deprived neonatal broilers. 2. In experiment 1 …

Animals at the neonatal stage have to eat more to support better growth and health.
However, it is difficult to understand the mechanism of feeding during an early stage of life in …

The present review considers the putative hormonal opioid peptides in birds. In birds and all
other vertebrates, there are four opioid related genes encoding a series of peptides. These …
