New research suggests that the brain has an interconnected network much like the Internet. Larry Swanson and Richard Thompson from the University of Southern California in Los Angeles isolated a small section of a rat's brain in the nucleus accumbens, which is a brain region associated with pleasure and reward. The scientists used a technique that hinges on the injection of "tracers" at precise points in the brain tissue.  These are molecules that do not interfere with the movement of...

Our belief as to whether we will likely succeed or fail at a given task"”and the consequences of winning or losing"”directly affects the levels of neural effort put forth in movement-planning circuits in the human cortex, according to a new brain-imaging study by neuroscientists at the California Institute of Technology (Caltech). A paper about the research"”led by Richard A. Andersen, the James G. Boswell Professor of Neuroscience at Caltech"”appears in the August...

By deciphering the genetics in humans and fish, scientists now believe that the neck "“ that little body part between your head and shoulders "“ gave humans so much freedom of movement that it played a surprising and major role in the evolution of the human brain, according to New York University and Cornell University neuroscientists in the online journal Nature Communications (July 27, 2010.) Scientists had assumed the pectoral fins in fish and the forelimbs (arms and hands) in...

A study released Monday shows that the parts of the human brain which grow the most during infancy and childhood are almost identical to the brain regions that have changed the most when humans are compared to primates. Researchers made the discovery while trying to understand abnormal brain development in premature babies and assess the long-term effects of premature birth on brain development. Terrie Inder, professor of pediatrics at Washington University in St. Louis and a lead author of...

Next time your brain plays tricks on you, you have an excuse: according to new research by UCL scientists published today in the journal Nature, the brain is intrinsically unreliable. This may not seem surprising to most of us, but it has puzzled neuroscientists for decades. Given that the brain is the most powerful computing device known, how can it perform so well even though the behaviour of its circuits is variable? A long-standing hypothesis is that the brain's circuitry actually is...

Jan-Ó¦ke Gustafsson investigates 'wireless connections' in the brain Many diseases of brain function, such as epilepsy and schizophrenia, are caused by problems in how neurons communicate with each other. A University of Houston (UH) researcher and his team are analyzing these commands and connections in an attempt to prevent those diseases. Dr. Jan-Ó¦ke Gustafsson, Robert A. Welch Professor in UH's biology and biochemistry department,...

BACKGROUND The ability to tell time is fundamental to how humans interact with each other and the world. Timing plays an important role, for example, in our ability to recognize speech patterns and to create music. Patterns are an essential part of timing. The human brain easily learns patterns, allowing us to recognize familiar patterns of shapes, like faces, and timed patterns, like the rhythm of a song. But exactly how the brain keeps time and learns patterns remains a mystery. FINDINGS In...

Our brains contain a highly distorted model of our own bodies, according to new research by scientists at UCL (University College London). A study published today, which focussed on the brain's representation of the hand, found that our model of our bodies is out of sync with reality "“ with a strong tendency to think that the hands are shorter and fatter than their true shape. The results of the study, published in the journal Proceedings of the National Academy of Sciences, show that...

BROOKLYN, N.Y., May 27 /PRNewswire/ -- In a letter received by Stanley I. Brookoff - the author of the new novel HYPERSPACE (published by AuthorHouse) - from noted French obstetrician, Frederick Leboyer, Dr. Leboyer wrote: "The mistreatment of the New-born is still, practically EVERYWHERE all over the world as criminal as ever." And what does Mr. Brookoff contend is the end result? Unimagined suffering of individuals, teen suicides, or a personality like Jason in HYPERSPACE. Perhaps the...

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

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...
