When your head gets a little tired and you’ve been waiting around for some time, you might have noticed that your brain’s electrical activity is getting more erratic and less steady.
This is called “theta activity” and can make you feel less “engaged” in your task.
Theta activity is usually more pronounced during the day and at night, and can be triggered by certain triggers such as reading a book or watching a movie, but when it is active, it can make it difficult to focus and concentrate on tasks.
In other words, it is a “signal” that something is happening.
But what happens when we don’t have a clear understanding of the signals that our brains are sending?
A new type is in the process of being developed.
“We’re trying to develop a way to look at the brain that’s going to allow us to look for signals in the brain and determine whether they’re there,” says David G. Miller, a professor of cognitive neuroscience at the University of Rochester in New York.
That’s a big step forward, because the idea is to understand the signals from the brain’s activity that might be responsible for a person’s actions.
A lot of the research on the brain-mind connection is coming out of neuroscience.
And the idea here is that we can look at these signals and find the cause of an action that might have triggered the action.
And if we can identify those signals, it might help us develop a therapy for disorders that affect a lot of people.
The first test for the new approach is to see if the treatment can reduce activity in certain brain regions.
“The test will be to see whether the changes are clinically meaningful,” Miller says.
That is, can we reduce the amount of activity in areas of the brain associated with action, motivation, decision making and other cognitive functions?
“We’ll be using fMRI, which is a technique that lets you measure brain activity in real time,” says Daniel F. Bogaert, a neurologist at the National Institute on Aging in Bethesda, Maryland.
The team is developing a method for comparing brain activity between different types of people to see how their brain activity changes over time.
The technique, called functional magnetic resonance imaging (fMRI), is used to identify changes in brain activity with the help of electrodes implanted in the head.
It is based on the idea that changes in the electrical activity of a specific brain region can be measured using a computer.
But unlike EEG, the new method relies on using light instead of sound, which makes it easier to measure brain signals at longer times.
And with light, the signal is much more easily seen.
A light microscope image shows an area in the left brain, which receives signals from two different neurons.
A large amount of light from a computer screen is turned into a light beam that hits the two neurons.

“What we’re looking at is what’s happening in the different parts,” says Miller.
“It could be a signal that’s producing a different type of neural activity in different parts.
We’re looking to see what’s going on in the neural circuitry, and what it might mean for what’s taking place.”
In a separate study, the team will try to use the fMRI method to determine whether brain stimulation can improve memory in people with Alzheimer’s disease.
It’s not clear whether this will be a real-world application, but it could help in some ways, says Miller, who is also a member of the Alzheimer’s Association of America.
“You might be able to get the same kind of improvements in people who have mild cognitive impairment that you get in people,” Miller said.
“But if you have Alzheimer’s, there are some problems that may limit the usefulness of that approach.”
Miller says he thinks the new technique could be used to study the effects of various types of brain stimulation, including light and sound, on the development of memory and learning.
A study of the fMRIs in people undergoing brain surgery for stroke found that they had better cognitive function in the two months following the surgery than those who were treated with other therapies.
Miller hopes that this technique can be used in people as well, so that they can be given a chance to test whether the technique will help improve memory or learning.
In the meantime, he says, it’s an important step forward.
“When we’re trying things like this, we don
