Neuroscience is the study of the nervous system, which includes the brain and the spinal cord. It's a broad term encompassing numerous, more specific disciplines, including cognitive, clinical, and developmental neuroscience.

It took cartographers and explorers thousands of years to map every nook, cranny, and crevasse of planet Earth. Now, a consortium of researchers from across the U.S. is going to try to map the entire human brain in just five.
An updated version of a neurochip can monitor brain cells' communications at the clearest resolution yet, according to scientists in Canada. It's cellular-scale mind-reading -- or mind-listening, to be more precise.
Just about everyone can think of some memory he or she would rather forget. For some, it's something like a relationship gone wrong, or high school. For others -- like soldiers returning from war zones -- those bad memories can be highly disruptive, impeding the ability to live a normal life. But Puerto Rican researchers may have found a way to reduce the fear associated with our memories by injecting a naturally occurring chemical directly into the brain, replacing anxiety with feelings of security.
U.S. armed forces have been using video games to train troops for years, but the Office of the SecDef wants something way cooler than the combat simulators of yore. The OSD is soliciting proposals for a new kind of immersive training video that really gets inside troops' heads, using EEG, eye tracking, voice pattern recognition, and physiological indicators like heart rate and respiration, to help soldiers learn good decision-making skills in high-pressure environments.
The brain is a difficult place to wander around without a map. But while the human brain, with its billions of neurons, is far too vast a frontier for us to map using current means, researchers have been building a cell-by-cell detailed map of the neural pathways in the brains of fruit flies, shedding light on how the neurons in our own brains connect and function.
Understanding how the brain perceives the passage of time could lead to treatments for mental illnesses. Why does time seem to slow down during a life-threatening situation? Our reporter falls 15 stories to find out

A few moments ago, I was strapped into a harness and winched 150 feet into the air. Four massive steel girders support my weight, and I can see that I'm the highest object around for miles. I am about to become the fastest-moving man in science, and I can barely keep my breakfast down.
This contraption is called the Suspended Catch Air Device, but the folks at the Zero Gravity Thrill Amusement Park in Dallas prefer the more colloquial "Nothin' But Net." That's because when the operator releases my rope, I will fall, untethered, until I plop into a modified circus net. The terrifying free fall will last less than three seconds, but to me it will feel much longer. And in this experiment, that is exactly the point.
Electrode implants which zap areas of the brain have mysteriously helped ease the symptoms of crippling diseases such as depression and Parkinson's. Now brain scans could help predict who exactly might benefit from deep brain stimulation (DBS), based on seeing which interconnected regions of the brain "light up" at the same time, New Scientist reports.
Moral judgments often have less to do with outcome and more to do with intention. Take murder, for instance: The U.S. legal system makes distinctions between a crime committed in the heat of the moment and one that is planned ahead of time. But moral judgments may not be as sacrosanct as we believe: MIT scientists have shown that they can alter our moral judgments simply by magnetically interfering with a certain part of the brain.
The brain is the body's most complicated biological machine, and as such it can be very difficult to service when something goes wrong; after our neural wiring is put in place, at a very young age, altering or rebuilding it becomes extremely challenging.
Time to get some of those iridescent Chris Moneymaker glasses. According to a new study published in the journal Current Biology your eyes could give away not just whether you have a good hand or not, but the actual numbers of the cards in your hand. Researchers asked study participants to name a string of random numbers, and by measuring horizontal and vertical eyes position the researchers were able to reliably predict the next number before it was spoken. Your bluff just might be toast.
