When it comes to brains, bigger is not always better Researchers at Centre for Ecological Research and Forestry Applications (CREAF, a Universitat Autònoma de Barcelona-affiliated center) shed new light on the evolution of brain size in birds. Scientists have known for some time that migratory birds have smaller brains than their resident relatives. Now a new study looks into the reasons and concludes that the act of migrating leads to a reduced brain size. Authors point to...

Toward intelligent and creative computers Information processing circuits in digital computers are static. In our brains, information processing circuits"”neurons"”evolve continuously to solve complex problems. Now, an international research team from Japan and Michigan Technological University has created a similar process of circuit evolution in an organic molecular layer that can solve complex problems. This is the first time a brain-like "evolutionary circuit" has been...

Did you ever wonder how you are able to perform complex tasks - even under stress? And how do emotions and memories mould your ability to live your everyday lives? The answer is just beginning to be understood and lies in hidden circuits in the brain. Pioneering work by Roger Pocock, a newly arrived Group Leader at the research center BRIC, University of Copenhagen, reveals the remarkable ability of organisms to activate latent neuronal circuits under stressful conditions. It is suggested...

Bile secretions in the small intestine send signals to disease-causing gut bacteria allowing them to change their behavior to maximize their chances of surviving, says Dr Steve Hamner, presenting his work at the Society for General Microbiology's spring meeting in Edinburgh yesterday (March 30). The findings could allow us to better protect food from contamination by these harmful bacteria, as well as understand how they manage to cause disease. Bile is secreted into the small intestine and...

SANTA FE, N.M., March 30 /PRNewswire/ -- Does the brain you were born with have to be the brain you end up with? If you can improve the function of every major organ in the body, why can't you upgrade the function of your brain? Those fundamental questions were the motivation that led Kelly Howell to create Brain Sync. With over 2 million audio programs in print, Kelly Howell's clinically proven Brainwave Therapy is used in prestigious hospitals, clinics and by physicians and...

Research presented by P&G Beauty & Grooming scientists at the 68th Annual Meeting of the American Academy of Dermatology (Miami Beach, FL, March 5-9) examines skin care science from multiple perspectives, offering insights into how ingredient formulations, care regimens and gene expressions impact skin condition. Eleven studies are on display, discussing a wide range of topics, including lipid metabolism pathways in the stratum corneum, skin elasticity and male shaving regimens. "This...

Scientists at the Queensland Brain Institute have uncovered a vital clue into how the brain is wired, which could eventually steer research into nervous system disorders such as Parkinson's disease and cognitive disorders including autism. It's long been known that growing nerve fibres, also known as axons, must make connections in the brain for it to function properly. "During the brain's development, billions of nerve cells send out nerve fibres which have to find the appropriate targets...

A medical breakthrough has brought the use of pig lungs in transplants to humans a step closer. Scientists in Melbourne Australia used a ventilator and pump to keep the animal lungs alive and "breathing" while human blood flows through them, the Telegraph recently reported. Experts believe that within five years, this work might lead to the first animal-human transplant. Dr Glenn Westall, who helped conduct the experiment, said: "The blood went into the lungs without oxygen and came out...

Scientists at Duke University Medical Center have identified neurons in the songbird brain that convey the auditory feedback needed to learn a song. Their research lays the foundation for improving human speech, for example, in people whose auditory nerves are damaged and who must learn to speak without the benefit of hearing their own voices. "This work is the first study to identify an auditory feedback pathway in the brain that is harnessed for learned vocal control," said Richard Mooney,...

In the field of hepatic imaging in the context of living liver donors and before complex partial liver resections, three-dimensional imaging of the liver, hepatic vessels and bile ducts has managed to become established in some centers. In this case, in addition to visualization, the volumetry of various liver sections is of interest. Moreover, the three-dimensional reconstruction can be used preoperatively to consider various resection options and to evaluate their technical feasibility with...

Liver
2013-04-30 14:18:06

The liver is the organ in charge of processing, neutralizing and excreting certain secretions for the metabolic processes. Formation and Orientation The liver is considered to be both the largest internal organ and the largest gland in the human body. It is situated just below the diaphragm, to the right of the stomach and on top of the gallbladder. There are two ways blood can travel to and from the liver: the hepatic artery and the portal vein. The hepatic artery carries blood solely...

Esophagus
2013-04-30 13:37:01

The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...

Ovaries
2013-03-05 14:55:04

The ovaries are the two reproductive female organs where the eggs are produced. These are parallel to the testes in men. Formation and Orientation Each ovary is the size of an almond and is located on one side of the pelvis before the ureter and internal iliac artery but after the external iliac artery. They are attached to either side of the uterus. They are connected and release eggs to fallopian tubes, though not attached, monthly during the menstrual cycle. They also produce...

Skin

Skin is the outermost organ that protects and incases the tendons, ligaments, bones, muscles, etc. It is also the largest organ of the human body. Formation and Orientation Healthy skin consists of vitamins A, C, D and E, but in all skin, there are melanocytes which produce mesodermal cells. These cells allow for the absorption of UV rays. There are five main pigments that provide color in the skin’s many levels. Although not found in the skin, Oxyhemoglobin is found in the blood,...

Appendix

The appendix is a dead-end tube like structure, ranging from 2 to 20 cm, that spans off the cecum of the colon. It is attached to the lower part of the large intestine. Formation and Orientation The appendix can be found in many mammals including marsupials, euarchontoglires (rodents) as wells as humans of course. It is also an organ that forms in the embryotic stage during pregnancy. McBurney’s Point, the point that is one-third the distance from infront and above the spinal cord...
