The brain is home to many different types of cells and tissues, and while we can’t tell which ones are responsible for a person’s symptoms, we can tell when they’re present.
In a new study published in the journal Nature Neuroscience, researchers have discovered that neurons in the human nervous system are capable of detecting a nervous system that has been artificially manipulated.
It’s the first time we know that a brain-based test can detect a nervous component that’s been artificially generated.
In the study, the team, led by Dr. Paul J. Siegel of the Institute for Brain and Cognitive Sciences at Columbia University, used a technique called magnetic resonance imaging (MRI) to examine the brain activity of healthy volunteers.
Using an MRI machine, they were able to record the electrical activity of a part of the brain called the basal ganglia, which is involved in processing movement and sensory input.
They found that when a stimulus was presented that caused the basal group to respond with a certain number of spikes, it meant that a person was having a specific kind of nervous system, such as an anamnestic nervous system.
“This study has shown us that our nervous system can detect that, and that it can tell whether the person is having a certain kind of response,” Siegel told Phys.org.
“We were really surprised at how accurately the activity we recorded matched what the brain was reporting.”
This is important because when a person has an anamestic nervous condition, there is a strong tendency to have a certain level of activity in the basal Ganglia that indicates a general nervous system condition, rather than an anamoesthetic one.
The team also discovered that they could test for this activity using a different type of test called functional magnetic resonance spectroscopy (fMRI).
“If we can get rid of the stimulus and the pattern of activity, and we can detect the presence of these two components, then we can use this as a diagnostic tool,” Sauer said.
“So, we have a way of seeing what’s going on in the brain in the case of a particular condition, and then the person can go back and see how they respond to that stimulus.”
The researchers are now planning to conduct more tests to see whether they can predict the severity of an anamed response.
“There is still a lot we don’t know about how anamemetic activity in brain-controlled systems works,” Sussheimer said.
