Population of Highly Active Neurons Could Provide Insight Into the Neocortex Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks. Like Facebook, these neuronal networks have a small population of highly active members who give and receive more information than the majority of other members, says Alison Barth, associate professor of biological sciences at Carnegie Mellon...

UCSF scientists have discovered a new stem cell in the developing human brain. The cell produces nerve cells that help form the neocortex "“ the site of higher cognitive function"”and likely accounts for the dramatic expansion of the region in the lineages that lead to man, the researchers say. Future studies of these cells are expected to shed light on developmental diseases such as autism and schizophrenia and malformations of brain development, including microcephaly,...

How stem cells yield functional regions in 'gray matter' The cerebral cortex, the largest and most complex component of the brain, is unique to mammals and alone has evolved human specializations. Although at first all stem cells in charge of building the cerebral cortex"”the outermost layer of neurons commonly referred to as gray matter"”are created equal, soon they irrevocably commit to forming specific cortical regions. But how the stem cells' destiny is determined has remained...

New study shows striking similarity in the evolution of brains, cities Cities are organized like brains, and the evolution of cities mirrors the evolution of human and animal brains, according to a new study by researchers at Rensselaer Polytechnic Institute. Just as advanced mammalian brains require a robust neural network to achieve richer and more complex thought, large cities require advanced highways and transportation systems to allow larger and more productive populations. The new...

A leading scientist has claimed that a detailed, functional artificial human brain could be built within the next 10 years, BBC News reported. Henry Markram, director of the Blue Brain Project, has already simulated elements of a rat brain. A synthetic human brain would be of particular use finding treatments for mental illnesses, Markram told the TED Global conference in Oxford. He said some two billion people are thought to suffer some kind of brain impairment and that it is not impossible...

A replication of a small portion of the brain has been developed, based on careful construction of each molecule, and has successfully restored experimental results from actual brains, BBC News reported. By placing the so-called "Blue Brain" in a virtual body, signs of molecular and neural origins of thought and memory can be observed. The director leading the study stated that scaling the recreation of the human brain is simply a matter of money.  "It's not a question of years, it's...

Counter to prevailing wisdom that self-awareness is something only experienced by humans and a few other higher-end mammals, German scientists reported on Tuesday that magpies can recognize themselves in the mirror.  The discovery highlights the mental skills of some birds - an ability once believed to belong only to humans, chimpanzees, dolphins and elephants. "This is a remarkable capability that is at least a pre-requisite of self-recognition and might play a role in perspective...

LONDON -- International Business Machines Corp (IBM) is linking with a team of Swiss scientists to create the world's first accurate, computer-based model of the brain, the U.S. company said on Monday. The researchers hope that modeling the brain at the cellular level will give new insights into the workings of the most complex organ in the body. The immediate goal is to model the circuitry in the neocortex, which accounts for about 85 percent of the human brain's mass and is thought to be...

  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
