Michael Gazzaniga: Split brains and other heady tales
Beyond the hype of left brain versus right brain lies the work of acclaimed neuroscientist Michael Gazzaniga. His career was forged in the lab of Nobel laureate Roger Sperry, and together their trailblazing experiments have illuminated the differences between the brain's two hemispheres. All In The Mind - 14 November 2009 -
Humans Still Evolving as Our Brains Shrink | LiveScience
Evolution in humans is commonly thought to have essentially stopped in recent times. But there are plenty of examples that the human race is still evolving, including our brains, and there are even signs that our evolution may be accelerating.
UCLA Study: The Internet Is Altering Our Brains
Adults with little Internet experience show changes in their brain activity after just one week online, a new study finds.
Neuroskeptic: How Brain Cells Avoid Getting All Tied Up
During the development of the brain, young neurones need to form connections with other cells. But equally important, they need to avoid making connections with themselves.
Concepts are born in the hippocampus
Forming a concept involves selecting the important characteristics of our experiences and categorising them. The degree to which we are able to do this effectively is a defining characteristic of human intelligence. Yet little is known about how conceptual knowledge is created and used in the brain.

Brain Cells for Socializing
Allman was searching for a peculiar kind of brain cell that he suspects is a key to how the African elephant—like a human being—manages to stay attuned to the ever-shifting nuances of social interplay. These spindle-shaped brain cells, called von Economo neurons—named for the man who first described them—are found only in human beings, great apes and a handful of other notably gregarious creatures. Allman, 66, compares the brains of people and other animals to gain insight into the evolution of human behavior.

Animals can tell right from wrong - Telegraph
Animals possess a sense of morality that allows them to tell the difference between right and wrong, according to a controversial new book.
Brain Activity Associated With Phantom Limbs, Study Shows
Phantom limbs, often described after amputation, are also experienced as an extra limb in patients who are paralyzed on one side following a stroke. Referred to as supernumerary phantom limb (SPL), patients can usually perceive these limbs as a vivid somatosensory presence of an extra limb, but generally cannot see or intentionally move them. In some unusual cases, however, patients have reported seeing their phantom limb or feeling objects or body parts with it, which indicates that multiple areas of the brain may be involved in SPLs.

More Evidence That Intelligence Is Largely Inherited: Researchers Find That Genes Determine Brain's Processing Speed
In a study published recently in the Journal of Neuroscience, UCLA neurology professor Paul Thompson and colleagues used a new type of brain-imaging scanner to show that intelligence is strongly influenced by the quality of the brain's axons, or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.

Neuroscientists Map Intelligence In The Brain
Neuroscientists at the California Institute of Technology (Caltech) have conducted the most comprehensive brain mapping to date of the cognitive abilities measured by the Wechsler Adult Intelligence Scale (WAIS), the most widely used intelligence test in the world. The results offer new insight into how the various factors that comprise an "intelligence quotient" (IQ) score depend on particular regions of the brain.
Different neuron networks control fear of different threats
If you wanted to turn a rat into a fearless critter, unfazed by cats or bigger rats, the best way would be to neutralise a small pair of tiny structures in its brain called the dorsal premammillary nuclei, orPMD. According to new research by Simone Motta at the University of Sao Paolo, these small regions, nestled within a rat's hypothalamus, control its defensive instincts to both predators and other rats. (Not Exactly Rocket Science)
-
The front and side parts (the ventrolateral area) are concerned with threats from dominant and aggressive members of the same species
-
the rear and middle parts (the dorsomedial area) process the threats of cats and other predators.
Envy and Schadenfreude in the brain.
Takahasi et al. show that experiencing envy at another person's success activates pain-related neural circuitry, whereas experiencing schadenfreude--delight at someone else's misfortune--activates reward-related neural circuitry. (Deric Bownds' MindBlog)
