Self-awareness In Humans Is More Intricate Than Previously Thought
2012-08-23 07:18:36

Ancient Greek philosophers considered the ability to "know thyself" as the pinnacle of humanity. Now, thousands of years later, neuroscientists are trying to decipher precisely how the human brain constructs our sense of self. Self-awareness is defined as being aware of oneself, including one's traits, feelings, and behaviors. Neuroscientists have believed that three brain regions are critical for self-awareness: the insular cortex, the anterior cingulate cortex, and the medial prefrontal...

Research results reported in Restorative Neurology and Neuroscience Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves. Their results are...

Study Reveals Brain's Mysterious Switchboard Operator
2012-08-17 16:08:49

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found. The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the...

Brain Power, Not Muscle Strength Related To Force Of Karate Punch
2012-08-16 12:29:05

Connie K. Ho for redOrbit.com — Your Universe Online Brain scans of karate experts recently showed distinctive features. Researchers believe that the images show how the ability to punch for black belts and karate novices could be related to a certain feature in the brain. The researchers, hailing from Imperial College London and University College London, discovered differences in the structure of the connection between brain regions, otherwise known as white matter. To begin,...

Scientists from The Scripps Research Institute have identified a new stem cell population that may be responsible for giving birth to the neurons responsible for higher thinking. The finding also paves the way for scientists to produce these neurons in culture–a first step in developing better treatments for cognitive disorders, such as schizophrenia and autism, which result from disrupted connections among these brain cells. Published in the August 10, 2012 issue of the journal...

Imaging Neural Pathways In Brain Show Intelligence Levels
2012-08-02 12:51:02

Connie K. Ho for redOrbit.com — Your Universe Online The brain is an intricate part of the body to say the least. And new research has focused on the effect of neural connectivity on one area of these intricacies, imaging a person's brain to estimate their level of intelligence. Researchers have long thought that overall brain size can affect individual variations in intelligence. A past study delved into this particular topic and demonstrated that the brain´s lateral...

Link Between Touch And Emotion Discovered
2012-06-05 04:36:07

Connie K. Ho for redOrbit.com Sight. Sound. Touch. These are just a few of the senses that the body has. This theme of senses was the subject of a recent study by neuroscientists from the California Institute of Technology (Caltech) who reported a relationship between touch and emotion via the brain´s primary somatosensory cortex. The findings, described in a recent issue of the Proceedings of the National Academy of Sciences (PNAS), were discovered by researchers Valeria Gazzola...

University of Georgia researchers have developed a map of the human brain that shows great promise as a new guide to the inner workings of the body's most complex and critical organ. With this map, researchers hope to create a next-generation brain atlas that will be an alternative option to the atlas created by German anatomist Korbinian Brodmann more than 100 years ago, which is still commonly used in clinical and research settings. Tianming Liu, assistant professor of computer...

Max Planck scientists discover brain cells in monkeys that may be linked to self-awareness and empathy in humans The anterior insular cortex is a small brain region that plays a crucial role in human self-awareness and in related neuropsychiatric disorders. A unique cell type — the von Economo neuron (VEN) — is located there. For a long time, the VEN was assumed to be unique to humans, great apes, whales and elephants. Henry Evrard, neuroanatomist at the Max Planck Institute...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...

  • 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.
