Stickleback's Aggressive Behavior Studied
2012-11-15 18:15:46

University of Illinois at Urbana-Champaign With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away. Now researchers are mapping the genetic underpinnings of the stickleback's aggressive behavior. Armed with tools that allow them to see which genes are activated or deactivated in response to social encounters, a team from the University of Illinois has identified broad patterns of gene activity that...

One drink increases brain's functional connectivity Short-term alcohol intake can increase the activity of functional connections across the human brain when it is at rest, according to research published Oct 31 in the open access journal PLOS ONE by Panagiotis Bamidis and colleagues from the Aristotle University of Thessaloniki, Greece. Previous studies have shown that alcohol intake increases transmission of signals by the neurotransmitter GABA, present in 40% of the connections...

Scientists Map Brain White-Matter
2012-10-19 13:13:35

Lee Rannals for redOrbit.com — Your Universe Online A team of scientists has built the first roadmap of the white-matter microstructure in the human brain. The project, called CONNECT, was drawn up from leading research centers in the countries across Europe. Investigators met in Paris on Friday after three years of research to announce the conclusion of the project and present a paper on the findings. The new atlas of the white-matter microstructure combines...

Evolution Is A Matter Of Brawn Vs Brain
2012-10-16 06:07:56

April Flowers for redOrbit.com - Your Universe Online Brain size relevant to body size has been the most common measurement of intelligence in animals, but it may not be as dependent on evolutionary selection of the brain as was previously thought. This is according to a new study published this week in the Proceedings of the National Academy of Sciences. A generation of scientists has used brain size relative to body size to predict an animal's intelligence. An example is the human...

Researchers studying the origins of sudden cardiac death have found that in both men and women a thin placenta at birth was associated with sudden cardiac death. A thin placenta may result in a reduced flow of nutrients from the mother to the fetus. The authors suggest that sudden cardiac death may be initiated by impaired development of the autonomic nervous system in the womb, as a result of fetal malnutrition. The new study, published today in the International Journal of Epidemiology,...

By studying how birds master songs used in courtship, scientists at Duke University have found that regions of the brain involved in planning and controlling complex vocal sequences may also be necessary for memorizing sounds that serve as models for vocal imitation. In a paper appearing in the September 2012 issue of the journal Nature Neuroscience, researchers at Duke and Harvard universities observed the imitative vocal learning habits of male zebra finches to pinpoint which circuits in...

You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, investigators at the Stanford University School of Medicine – having done the equivalent of wire-tapping a hard-to-reach region of the brain – can tell us how this impasse arises. The researchers showed that groups of nerve cells in a structure called the posterior medial cortex, or PMC, are strongly activated during a recall task such as trying to remember whether you had...

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

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,...

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...
