To establish connection, brain synchronises sound waves: Study

Published

on

Bern [Switzerland], February 9 (ANI): Have you ever imagined how we determine from which direction sounds are coming from? Why human beings don’t hear everything twice? Well, this is what our brain has to be praised for. Researchers from the University of Zurich explained how the brain combines the information from both ears to avoid echo while listening.
In addition, input from the right ear reaches the left brain hemisphere first, while input from the left ear reaches the right brain hemisphere first. The two hemispheres perform different tasks during speech processing: The left side is responsible for distinguishing phonemes and syllables, whereas the right side recognises the speech prosody and rhythm. Although each hemisphere receives the information at a different time and processes different features of speech, the brain integrates what it hears into a unified speech sound.
The exact mechanism behind this integration process was not known until now. In earlier studies, however, Preisig had found indications that measurable oscillations elicited by the brain – known as gamma waves – played a role.
Now he has managed to demonstrate that the process of integrating what we hear is directly linked to synchronisation by gamma waves. Neurolinguistics from UZH worked on the project alongside researchers from the Netherlands and France.
The study, which took place at the Donders Center for Cognitive Neuroimaging in Nijmegen, the Netherlands, involved 28 healthy subjects who had to repeatedly solve a listening task: An ambiguous syllable (a speech sound between ga and da) was played in their right ear while a click containing a fragment of the syllables da or ga was played unnoticed in the left ear.
Depending on what was played in their left ear, the participants heard either ga or da and then had to report what sound they had heard. During the process, the researchers were tracking activity in both hemispheres of the brain using functional magnetic resonance imaging (fMRI).
During the experiments, the researchers disrupted the natural activity pattern of gamma waves by stimulating both hemispheres of the brain with electrodes attached to the head. This manipulation affected participants’ ability to correctly identify the syllable they heard.
The fMRI analysis showed that there were also changes in the activity of the neural connections between the right and the left brain hemispheres: The strength of the connection changed depending on whether the rhythm of the gamma waves was influenced by electric stimulation in the two brain hemispheres synchronously or asynchronously.
This disruption also impaired the integration process. Thus, synchronisation of the gamma waves seems to serve to balance the different inputs from the two hemispheres of the brain, providing a unified auditory impression.
“Our results suggest that gamma wave-mediated synchronisation between different brain areas is a fundamental mechanism for neural integration,” said Preisig. “Moreover, this research shows for the first time, using human hearing as an example, that the connection between the two hemispheres of the brain can be successfully modulated by electric stimulation,” adds Alexis Hervais-Adelman, head of neurolinguistics at the UZH Department of Psychology, who was also involved in the study.
These findings could thus also find clinical application in the near future. “Previous studies show that disturbances in the connection between the two hemispheres of the brain are associated with auditory phantom perceptions such as tinnitus and auditory verbal hallucinations,” Preisig adds. “Thus, electric brain stimulation may present a promising avenue for the development of therapeutic interventions.” (ANI)

Superstar Aamir Khan is celebrating 20 years since the release of his iconic film ‘Lagaan’. The movie, helmed by Ashutosh Gowariker, was nominated for the Oscars and appreciated by critics and audiences alike. Reminiscing about the journey of making the film, Aamir recalled that no one was ready to back it. Ashutosh narrated him the film’s script a few times and he enjoyed it but was not ready to produce it initially as he did not want to dive into film production. Every time Aamir would meet Ashutosh he would bring up the film but was told that no one was ready to produce it. He finally took the plunge to produce it and act in it after listening to the script again in the company of his parents and ex-wife Reena who enjoyed the story.

I WAS REJECTED FROM 250 AUDITIONS BEFORE ‘MARDAANI’: TAHIR

Published

MUMBAI: Tahir Raj Bhasin recently revealed that he was rejected 250 times before he was signed on by Aditya Chopra for ‘Mardaani’.

Tahir said, “Anything that’s worthwhile takes time and this is something I understood when I first came to Mumbai. I was rejected from some 250 auditions over 3 years before Mardaani but I used this as positive fuel and feedback. It meant I needed to grow and growth came from workshops and hours of practice.” He added, “The improvements that came as a result of obstacles prepared me to be propelled when the time was right. Strength lay in getting hit and in the will to keep moving forward. Today’s world is all about that simple message. We have all been affected directly or indirectly by an unforeseen time and courage is to make ourselves better, fitter and stronger for the test of time to come.”

Despite the overwhelming number of rejections, Tahir never lost hope and believed he was destined to shine in Bollywood. He said, “To be honest, I never saw my initial time in Mumbai as a struggling phase. It was an aspiring phase. I was visualising a dream and aspiring to make it real and it’s the hardship and journey that make the successes worth celebrating.”

Tahir’s upcoming projects include ‘Looop Lapeta’, ‘Bulbul Tarang’, ‘Yeh Kaali Kaali Ankhein’, and ‘83’.
