  • Researchers have discovered how the protein Hap1, which is abundant in the brain's hypothalamus, serves as the link between circulating insulin in the blood and the neural circuitry that controls feeding behavior in mice. (rxpgnews.com)
  • Hormones such as insulin and leptin, which circulate in the blood plasma, are known to play an important role in regulating the brain's feeding signals, but scientists have not fully understand how these hormones interact with the brain circuitry. (rxpgnews.com)
  • We concluded that increased levels of Hap1 correlated with increased feeding behavior in the mice, and our research helps explain how Hap1 is linked to feeding-related molecules such as insulin, and to hypothalamic neuronal function," said Xiao-Jiang Li, PhD, professor of human genetics at Emory University School of Medicine and senior author of the study. (rxpgnews.com)
  • Because insulin decreases Hap1 levels, and reducing Hap1 decreases the GABA receptor activity, we believe Hap1 is the link between circulating insulin and the regulation of GABA receptors in the hypothalamus in controlling eating behavior. (rxpgnews.com)

  • In a new study published in the open access journal PLoS Biology, Drs. Marm Kilpatrick, Peter Daszak, and colleagues now present evidence that the major vector of West Nile virus in the USA, Culex pipiens mosquitoes, change their feeding behavior in the fall from their preferred host, American robins, to humans, resulting in large scale outbreaks of disease. (eurekalert.org)
  • As the summer wore on and robins left their breeding grounds, the probability that humans were fed on increased sevenfold. (eurekalert.org)
  • predators
  • The black bear's generalist behavior allowed it to exploit a wider variety of foods and has been given as a reason why, of these three genera, it alone survived climate and vegetative changes through the last ice age while the other more specialized North American predators became extinct. (wikipedia.org)
  • This singular behavior may assist them in extricating themselves from the jaws of predatory fish or from the interior of their own "prey", and the "sliming" might act as a distraction to predators. (wikipedia.org)

  • The system can accommodate 128 animals, and the antennas were designed to read tags within the feed bunk at a maximum of 30 inches. (rfidjournal.com)
  • 0.001 versus well-fed animals, unless otherwise indicated. (nih.gov)
  • In addition, the lack of kinematic change through ontogeny indicates that feeding kinematics do not scale with body size, contrary to predictions that movements should be slower in larger animals. (biologists.org)
  • Animal
  • The lunge feeding of blue whales is an extraordinary biomechanical event in which the largest animal on Earth accelerates and opens its mouth under water, expanding its enormous throat pouch to engulf a huge volume of water, then filtering out its prey (small crustaceans called krill) by forcing the water through sieve-like baleen plates. (eurekalert.org)
  • Two agricultural engineers working for the U.S. Department of Agriculture (USDA) have developed an animal feeding behavior-monitoring system that employs radio frequency identification readers, antennas and multiplexers to gauge the health of livestock. (rfidjournal.com)
  • prey
  • The smaller rolls to the right when feeding at depth probably relate to the biomechanics of opening the mouth rather than visual targeting of prey, he said. (eurekalert.org)
  • These results indicate that the initial prey-capture behavior remains unchanged throughout larval ontogeny. (biologists.org)
  • Larger still are the massive daggers of the two adjutants and marabou (Leptoptilos), which are used to feed on carrion and in defence against other scavengers, as well as for taking other prey. (wikipedia.org)
  • They feed by masticating their prey and sucking out the liquids. (wikipedia.org)
  • mainly
  • The Asian openbill feeds mainly on large molluscs, especially Pila species, and they separate the shell from the body of the snail using the tip of the beak. (wikipedia.org)
  • They are carnivores which feed mainly on other invertebrates. (wikipedia.org)
  • brain
  • As far back as 1951, Anand and Brobeck [ 1 ] reported that bilateral destruction of the lateral hypothalamus (LH) in rats resulted in the complete absence of eating, leading them to term this area of the brain the "feeding center. (hindawi.com)
  • While a number of classical neurotransmitters have been implicated in LH-induced feeding, the discovery of neuropeptides in the brain [ 4 ] has led researchers to consider several of these local neuromodulatory neurochemicals as major players in feeding and reward. (hindawi.com)
