According to researchers, nearly half the brain’s cells are capable of performing new functions

Published on

Researchers at Tufts University discovered a previously undiscovered function that was performed by a cell type which contains nearly half of all brain cells.
The journal Nature Neuroscience published the findings of the research.
Scientists believe that the discovery of a new function in astrocytes by mice opens up a new avenue for neuroscience research. This could lead to new treatments for many disorders, including epilepsy, Alzheimer’s, and traumatic brain injury.
It is all about how astrocytes interact and communicate with neurons, the fundamental cells of the brain that receive input from the external world. Neurons transmit information through complex electrical and chemical signals between different parts of the brain as well as between the brain, the rest of the nervous systems, and other areas.
Scientists had believed that astrocytes were essential, but they were of lesser importance. Astrocytes are responsible for the growth and development of axons. These are the long, thin projections of neurons that conduct electrical impulses. They also control neurotransmitters which are chemicals that facilitate the transfer of electrical signal throughout the nervous system and brain.
Asteroid cells are also responsible for the blood-brain barrier being built and their ability to react to injuries. However, they didn’t seem to be as active electrically as the essential neurons until now. Chris Dulla is an associate professor of neuroscience at the School of Medicine, Graduate School of Biomedical Sciences. “The electrical activity of Astrocytes changes how neurons function,” he said.
“We have discovered a way in which two of the most important brain cells can communicate.” It is crucial to discover new processes that control brain function because so much is still unknown about the brain’s workings. This will allow us to develop novel treatments for neurological disorders.

Dulla and Moritz armbruster, who is also the study’s lead author, are Saptarnab Naskar, Mary Sommer, Elliot Kim, and Philip G. Haydon, both from Tufts University School of Medicine. Jacqueline P. Garcia, Cell, Molecular and Developmental Biology at Tufts Graduate School of Biomedical Sciences, and other researchers from other institutions.
The team created a brand new technology technique to study and observe the electrical properties of brain-cell interactions.
Armbruster, research assistant professor of neuroscience in the School of Medicine, said, “With these new instruments, we’ve basically uncovered completely new aspects of biology.” We’ll be able to understand more things as we use better tools, such as fluorescent sensors that are constantly being developed.
Dulla explained that the new technology “images electrical activity with lights.” “Neurons are extremely electrically active and the new technology permits us to see that also astrocytes can be electrically active.”
Dulla defines astrocytes “as making sure that everything is in order in the brain. If something goes wrong, they detect it and try to respond and then protect the brain against insult. Next, we will examine how astrocytes react to insults.
Neuron-to–neuron communication takes place through the release packets of chemicals known as neurotransmitters. Scientists understood that Neurons-to-neuron communications are important in keeping neurons healthy and active. The new study shows that neurons also release potassiumions. These ions can alter the electrical activity of the cells and control the neurotransmitters.
“So, the neuron controls what the astrocyte does and they communicate back and forth. He explained that neurons and the astrocytes talk in a new way.
