Call a bird "birdbrained" and they may call "fowl." Cornell University researchers have proven that the capacity for learning in birds is not linked to overall brain size, but to the relative size and proportion of their specific brain regions. Songbirds with upper brain regions that are larger in relation to lower regions have a greater capacity for learning songs. Higher brain areas control the majority of cognitive and learning functions, while lower brain areas control more motor...

By Miles O'Brien, Science Nation Correspondent Picking people's brains is a good way to learn about their minds, says neuroanatomist Jacopo Annese. "We're studying brain structure and trying to understand how the architecture of the brain supports our behavior, our thoughts, our memories, our way of thinking," says Annese. Annese heads the Brain Observatory at the University of California, San Diego. It's where he and his team look for connections by mapping brain structure and connecting it...

SAUSALITO, Calif., July 26, 2011 /PRNewswire/ -- For years, the brain was a slow-to-solve mystery for scientists and the public alike. But today it's more a "marvel," thanks to exciting research, technology and educational breakthroughs over the last decade. In fact, even children as young as four are now soaking up the brain's secrets, thanks to Morphonix(TM) LLC (http://www.morphonix.com), a company devoted to using games to teach kids all about the brain. Morphonix has been winning...

Research conducted by Maria Ercsey-Ravasz and Zoltan Toroczkai of the University of Notre Dame's Interdisciplinary Center for Network Science and Applications (iCeNSA), along with the Department of Physics and a group of neuroanatomists in France, has revealed previously unknown information about the primate brain. The researchers published an article in the journal Cerebral Cortex showing that the brain is characterized by a highly consistent, weighted network among the functional areas of...

Scientists have shed light on why it is easier to learn about things related to what we already know than it is to learn about unfamiliar things, according to a new study. The team says this is a paradox, as very different things are arguably more novel, yet adding to what we already know is so much easier. Researchers at the Universities of Edinburgh and Tokyo have found that building on existing knowledge activates a key set of genes in the brain. These 'plasticity' genes do not respond so...

Bringing the real world into the brain scanner, researchers at The University of Western Ontario from The Centre for Brain and Mind (http://www.uwo.ca/its/brain/) can now determine the action a person was planning, mere moments before that action is actually executed. The findings were published this week in the prestigious Journal of Neuroscience, in the paper, "Decoding Action Intentions from Preparatory Brain Activity in Human Parieto-Frontal Networks." "This is a considerable step forward...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
