Researchers at Stanford and at the Pierre and Marie Curie University in France had targeted neurons in the mouse brain's cortex and thalamus known to be overactive during seizures.
WSJ: Scientists Cast Light Onto Roots of Illness Deep in the Brain
Marco Iacoboni, a lab director at the UCLA Brain Mapping Center, says when people see a smile, so-called mirror neurons fire in their brain and evoke a similar neural response as if they were smiling themselves.
Men and boys with autism have fewer neurons in a part of the brain involved in memory and emotion, according to a new study by scientists at the University of California in San Diego and the MIND Institute at UC Davis.
The neuroscience behind limbic synchrony has everything to do with the discovery of mirror neurons and how empathy develops in the brain.
Now the Nvidia chips teenagers use in Unreal Tournament are basically the same ones used by scientists at Evolved Machines in Palo Alto, California who are simulating neurons used by the brain to see and smell.

They studied the nerve cells that regulate appetite using a 'genetic fate mapping' technique and found that some cells added neurons to the appetite-regulating circuitry of the mouse brain after birth and into adulthood.
Besides being cheap and disposable, a mouse brain weighs half a gram and packs a mere 16m neurons.
New Scientist magazine reports that the researchers, led by Mark Tuszynski, of the University of California, San Diego, believe a substance called nerve growth factor (NGF) can prevent the death of cells in the brain known as cholinergenic neurons, and stimulate new connections between the cells.
It could recognize "practice" movements and deliver stimulation to associated neurons to help your brain learn faster.
Her research represents just one piece of a massive worldwide effort being conducted to unravel the seemingly unfathomable complexity of the brain, with its billions of neurons and connections.
The US team showed that DISC1 plays a key role in normal brain development and the growth of individual neurons.
Researchers at Stanford University and MIT's Picower Institute for Learning and Memory had activated light-sensitive neurons in the brain's hippocampus involved in the memory of fright.

Enough probably is already known to say that consciousness arises somehow out of the activity of billions of neurons, and every year more is learned about the mechanisms of the brain.
So, the thinking goes, when something depressing happens to a chronically stressed or anxious person, his brain is unable to bounce back by creating new neurons and neuronal circuits signaling better times ahead.
In the brain, neurons work together over synapses to recognize a pattern and make the closest match.
This lag may be because after a stressor it takes a little time for the brain to respond and to encourage the growth of new neurons.
Attuned to the activity between neurons, a neural implant can essentially "listen" to your brain activity and then "talk" directly to your brain.
The effect should be fleeting, enough to warm up the brain's food neurons, kick-start the taste buds, and crank open the saliva glands.
Instead, suvorexant turns off a different set of switches, known as orexin receptors, which are involved in waking people up and are only present in 70, 000 neurons in a particular place in the brain.
FORBES: Can A Safer Ambien Make Billions? Merck Aims To Find Out
In one application of optogenetics, scientists investigated how neurons that make dopamine, a neurotransmitter in the brain, may give rise to feelings of reward and pleasure.
When hyperpolarized, neurons don't fire as often, which makes parts of the brain that induce feelings of anxiety and fear less active.
Buchholz and Spalding first were trying to use this method to see if they could determine whether neurons in the brain were grown once or if they were regenerated throughout a lifetime.
When you start something new, a large number of neurons in the frontal cortex (the higher, more conscious command area of the brain) are recruited and become active, helping you in the learning process.
FORBES: Why Apprenticeships Are the Fastest Way to Acquire Skills
Ricardo Dolmetsch, a researcher at Stanford University and the Allen Institute for Brain Sciences, is using stem cell technology to study how the neurons of people with autism differ from those of other people.
FORBES: More Prenatal Vitamins Could Mean Less Autism, Study Says
And it turns out that some of the regions where monkeys have mirror neurons correspond to areas of the human brain that handle language.
Researchers are now studying whether gut neurons, which can be sampled through a routine colonoscopy, may help clinicians diagnose and track the disease without invasive brain biopsies, says Pascal Derkinderen, a professor of neurology at Inserm, France's national institute of health.
Markram and IBM both emphasize that the project would not create artificial intelligence but a way to study how neurons in the brain interact with one another.
The EPOC detects and processes real time brain activity patterns (small voltage changes in the brain caused by the firing of neurons) using a device that measures electric activity in the brain.
While nerves in the arms, legs and peripheral organs can sprout back at the rate of up to 1 millimeter per day, adult neurons in the brain or spinal cord, the so-called gray matter, were long assumed incapable of growing back after an injury.
