The researchers found that by inducing repetitive high frequency firing of a single neuron they could switch the brain state from slow-wave sleep, to rapid-eye movement sleep.

Therefore, judging by these three high profile journal papers, a single neuron can make a difference - one neuron firing can change your sleep state, motor movement, or induce a behavior.

A detailed simulation of a small region of a brain built molecule by molecule has been constructed and has recreated experimental results from real brains.

While many computer simulations have attempted to code in "brain-like" computation or to mimic parts of the nervous systems and brains of a variety of animals, the Blue Brain project was conceived to reverse-engineer mammal brains from real laboratory data and to build up a computer model down to the level of the molecules that make them up.

The first phase of the project is now complete; researchers have modeled the neocortical column - a unit of the mammalian brain known as the neocortex which is responsible for higher brain functions and thought.

If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.

It may be that this quick activity helps facilitate interaction between the brain hemispheres.

any activity that encourages communication between the hemispheres is likely to increase recall.

But there has been one major payoff from our investigations of the brain: an increasing emphasis on educating young children, before they reach kindergarten. Decades of research have demonstrated that the cortex is astonishingly plastic at a young age and that many important traits and habits seem to solidify before the age of 4.

With the right training, scientists now know the brain can reshape itself to work around dead and damaged areas, often with dramatic benefits.

Therapies that exploit the brain's power to adapt have helped people overcome damage caused by strokes, depression, anxiety and learning disabilities, and may one day replace drugs for some of these conditions.

Children with language difficulties have been shown to make significant progress using computer training tools that are the equivalent of cerebral cross-training.

Next Mrs. Retallack tried another experiment again using the three chambers. In one chamber she played North Indian classical music performed by sitar and tabla, in another she played Bach organ music, and in the third, no music was played. The plants "liked" the North Indian classical music the best. In both the Bach and sitar chambers, the plants leaned toward the speakers, but he plants in the Indian music chamber leaned toward the speakers the most.

Mrs. Retallack placed plants in each chamber and speakers through which she played sounds and particular styles of music. She watched the plants and recorded their progress daily. She was astounded at what she discovered.

What the scientists found was that after a week of practice, the stretch of motor cortex devoted to these finger movements took over surrounding areas like dandelions on a suburban lawn.

He extended the experiment by having another group of volunteers merely think about practicing the piano exercise. They played the simple piece of music in their head, holding their hands still while imagining how they would move their fingers. Then they too sat beneath the TMS coil.

they glimpsed a revolutionary idea about the brain: the ability of mere thought to alter the physical structure and function of our gray matter. For what the TMS revealed was that the region of motor cortex that controls the piano-playing fingers also expanded in the brains of volunteers who imagined playing the music--just as it had in those who actually played it.

Our research findings provide a direct functional link between the bursting activity of midbrain dopamine neurons and behavior. The research has significant applications for the improvement of health, because the dopamine neurons we are studying are the same neurons that become inactivated during Parkinson's Disease and with the consumption of psychostimulants such as cocaine and amphetamine

Midbrain dopamine neurons fire in two characteristic modes, tonic and phasic, which are thought to modulate distinct aspects of behavior. When an unexpected reward is presented to an individual, midbrain dopamine neurons fire high frequency bursts of electrical activity. Those bursts of activity allow us to learn to associate the reward with cues in our environment, which may predict similar rewards in the future.

When researchers placed the mice in reward-based situations, they found that the mice without the NMDA receptor in their dopaminergic neurons could not learn tasks that required them to associate sensory cues with reward. Those same mice, however, were able to learn tasks that did not involve an association with rewards.

So instead of promoting retirement at age 65, perhaps we as a society should be promoting transition at age 65: transition into a creative field where our growing resource of individuals with aging brains can preserve their wisdom in culturally-valued works of art, music, or writing.

Numerous studies suggest that highly creative individuals also employ a broadened rather than focused state of attention. This state of widened attention allows the individual to have disparate bits of information in mind at the same time. Combining remote bits of information is the hallmark of the creative idea.

Other studies show that certain areas of the prefrontal cortex involved in self-conscious awareness and emotions are thinner in the aging brain. This may correlate with the diminished need to please and impress others, which is a notable characteristic of both aging individuals and creative luminaries.
