A study by the University of Barcelona (UB) has analyzed which facial features our brain examines to identify faces. Our brain adapts in order to obtain the maximum amount of information possible from each face and according to the study the key data for identification come from, in the first place, the eyes and then the shape of the mouth and nose.The objective of this study, undertaken by researcher Matthias S. Keil from the Basic Psychology Department of the UB and published in the...
U.S. researchers suggest childhood adversity may affect how the brain anticipates rewards. The study, published in Biological Psychiatry, suggests weaker responses of the brain to rewards might contribute to apathy, low motivation, or a reduced ability to experience pleasure. The Harvard University researchers used magnetic resonance imaging scanning to track neural reactions as two groups of adults played a game involving cues predicting monetary rewards and penalties. In the group that...
Japanese scientists are involved in groundbreaking research to understand and then rebuild the brains of insects and program them for specific tasks, AFP reported.After studying insect brains for three decades, Ryohei Kanzaki, a professor at Tokyo University's Research Center for Advanced Science and Technology, has become a pioneer in the field of insect-machine hybrids.Kanzaki has been studying insects' "micro-brains" in order to move closer to his original and ultimate goal of...
A study by scientists at Penn State provides new information about the genes that are involved in a mammal's early brain development, including those that contribute to neurological disorders. The study is the first to use high-throughput sequencing to uncover active genes in developing brains, and it is likely the best evidence thus far for the activity in the brain of such a large number of genes. The research results one day could lead to the development of drugs or gene therapies that...
MINNEAPOLIS, July 13 /PRNewswire-FirstCall/ -- Uroplasty, Inc. (NYSE Amex: UPI), a medical device company that develops, manufactures and markets innovative proprietary products for the treatment of voiding dysfunctions, announced today the issuance of United States Patent No. 7,536,226 entitled, "Electro-Nerve Stimulator System and Methods." The patent covers the company's Urgent(R) PC system and stimulation methods for treatment of the overactive bladder ("OAB") symptoms of urinary...
 When a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential switching on and off of thousands of genes after a bird hears a new tune offers a new picture of memory in the songbird brain.The finding, detailed this month in the Proceedings of the National Academy of Sciences, was a surprise, said principal investigator David Clayton, a professor of cell and developmental...
If you have hay fever, headaches or a cold, it's only a short way to the nearest chemist. The drugs, on the other hand, can take eight to ten years to develop. Until now animal experiments have been an essential step, yet they continue to raise ethical issues. "Our artificial organ systems are aimed at offering an alternative to animal experiments," says Professor Heike Mertsching of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart....
Are you a "morning person" or a "night owl?"Scientists at the University of Alberta have found that there are significant differences in the way our brains function depending on whether we're early risers or night owls.Neuroscientists in the Faculty of Physical Education and Recreation looked at two groups of people: those who wake up early and feel most productive in the morning, and those who were identified as evening people, those who typically felt livelier at night....
GES or pacing has been under investigation as a potential therapy for gastrointestinal motility disorders. Conventionally, GES is performed using a single pair of electrodes or single-channel GES. However, few studies have investigated the effects of two-channel GES with trains of pulses on gastric motility, such as gastric slow waves and gastric emptying. A research article to be published in May 21, 2009 in the World Journal of Gastroenterology addresses this question. The research...
Researchers said on Wednesday that the same part of the brain that makes us crave food and sex might also help determine whether somebody is a warm and sentimental "people" person, Reuters reported.The study, reported in the European Journal of Neuroscience Scientists, found a greater concentration of brain tissue in certain areas of the brain may drive some people to gush fuzzy feelings more than others.Graham Murray of Cambridge University in Britain, who led the study, said they...

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...
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...
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 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,...
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...
