New York: Scientists reported in a study that star-shaped brain cells appear to help in keeping blood pressure and blood flow inside the brain on a healthy tone.

The finger-like appendages of astrocytes, called end-feet, quite literally wrap around the countless, fragile blood vessels in the brain, constantly monitoring what is going on inside and around them.

“This is the first evidence of the astrocytes’ role in pressure-induced myogenic (muscle) tone, which is keeping things regular,” said Dr Jessica A Filosa, neurovascular physiologist at Georgia Regents University.

Filosa terms astrocytes as “housekeepers”. When they sense a change in blood pressure inside the brain, one of their duties is releasing signals that help dilate or constrict the blood vessels, whichever it takes to maintain the healthy status quo.

In fact, astrocytes keep their fingers on the pulse of blood vessels and neurons simultaneously, apparently playing an important role in balancing their needs.

“They are perfect bridges between what is going on with neuronal activity and blood flow changes to the brain.”

Astrocytes relentlessly monitor and respond to changes in blood pressure to help keep the brain from getting too much blood.

The team is now looking into what effect activating astrocytes has on neuronal activity.

The paper appeared in The Journal of Neuroscience. (IANS)

Contagious yawning: Why we yawn when someone else does? Read to find out

  • Contagious yawning is triggered involuntarily when we observe another person yawn, it is a common form of Echophenomena
  • The  Research findings showed that our urge to yawn is increased if we are instructed to resist yawning
  • Echophenomena isn’t just a human trait, it is found in chimpanzees and dogs too

New York, USA, September 3, 2017:  Ever wondered why even if we are not tired, we yawn if someone else does? Why is yawning so contagious?

It is because the human propensity for contagious yawning is triggered automatically by primitive reflexes in a brain area responsible for motor function, a research suggests.

Contagious yawning is triggered involuntarily when we observe another person yawn – it is a common form of Echophenomena -the automatic imitation of another’s words (echolalia) or actions (echopraxia).

The  Research findings showed that our urge to yawn is increased if we are instructed to resist yawning. And no matter how hard we try to stifle a yawn, it might change how we yawn but it won’t alter our propensity to yawn.

“This research has shown that the ‘urge’  is increased by trying to stop yourself. Using electrical stimulation we were able to increase excitability and in doing so increase the propensity for contagious yawning,” said Georgina Jackson, a Professor at the University of Nottingham.

“The findings may be important in understanding the association between motor excitability and the occurrence of Echophenomena in a wide range of conditions linked to increased cortical excitability and/or decreased physiological inhibition such as epilepsy, dementia, autism, and Tourette syndrome,” added Stephen Jackson, a Professor at the University.

For the study, published in the journal Current Biology, the team used transcranial magnetic stimulation (TMS) to analyze volunteers who viewed video clips showing someone else yawning and were instructed to either resist yawning or to allow themselves to yawn.

“If we can understand how alterations in cortical excitability give rise to neural disorders we can potentially reverse them. We are looking for potential non-drug, personalized treatments, using TMS that might be effective in modulating imbalances in the brain networks,” Jackson said.

Echophenomena isn’t just a human trait, it is found in chimpanzees and dogs too. (IANS)
