Sound of Mother’s voice : Aid for Fetal Brain growth


Tragedy of our times is that while mother should engage in life-enriching conversations with the womb, she has to attend conference calls, meetings, mobile games, whatsapp and all.

Imagine the frustration of the child in the womb for beginning life with such non-responsive parents?

I know few couples, who stopped using TV, mobile and all as soon as they realized to have a baby. Worth. Take care. Try it.

Even after birth, for first 2 years, dedicate your maximum time to child.

In India, grand mother prescribes pregnant females at home to read Ramayana and Mahabharata aloud. Instead, most of them now watch TV all the time :).
They suggest to sing Halarda to kids during sleeping time, but instead moms start mp3 on mobile :D.
Do you know why? Here is the hint:
“”Babies begin to hear at 25 weeks’ gestation, and they’re exposed to the mother’s voice and heartbeat,” Lahav said. “If you put them inside the incubator for five to six weeks, you’re actually depriving them of these maternal exposures to the mother’s voice. The incubator is seemingly a wonderful piece of equipment. But at the same time, it’s like a social cage.””
Even after birth, babies seek continuous hearing from mother. Her presence and voice help baby a lot in ongoing physical and mental development.
If I become Health Minister or can influence present minister, I will give full 2 years paid leaves to working mothers. 🙂

Sound of Mother’s Voice in Womb May Aid Fetal Brain Growth

Study of preemies who heard recordings from mom showed larger auditory cortex

Babies may get a brain boost in the womb when they hear the voices and heartbeats of their mothers, a new study suggests.

Researchers studying premature babies in the hospital found that the sound centers in the babies’ brains grew more quickly when they heard recordings of their mothers rather than the normal clamor of intensive care units. The recordings were manipulated to simulate sounds heard in a womb.

It’s not clear what this means in the long run, “but it shows how important it is for mothers to interact with their premature babies when they visit,” said study co-author Amir Lahav, an assistant professor of pediatrics at Harvard Medical School in Boston.

Babies born prematurely often suffer from hearing and language problems, Lahav explained, and the researchers wanted to know more about how they’re affected by the weeks they spend in an incubator instead of in their mother’s womb.

“Babies begin to hear at 25 weeks’ gestation, and they’re exposed to the mother’s voice and heartbeat,” Lahav said. “If you put them inside the incubator for five to six weeks, you’re actually depriving them of these maternal exposures to the mother’s voice. The incubator is seemingly a wonderful piece of equipment. But at the same time, it’s like a social cage.”

The study findings probably apply to all babies, one expert noted.

Previous research has shown that fetuses respond to the sound of the mother’s voice. At birth, babies take notice “and say, ‘Hey, that’s what I was waiting for,’ ” said Janet Werker, a psychology professor at the University of British Columbia in Vancouver.

“There’s very strong evidence that at birth, full-term babies show strong preference for the language they heard in utero and the voice of their mother over other women,” she said.

But it’s not clear if the mother’s voice is the only important one, since exposure to other voices could be just as critical, Werker added.

For this latest study, the researchers chose a group of premature babies who were born at 25 to 32 weeks. Nineteen were randomly assigned to hear the normal noises of the hospital, while 21 heard recordings of the voices and heartbeats of their mothers. The second group listened to the recordings for three hours a day.


Recitation vs Television : Visual Leakages

Visual leakage


When you listen Ramayana, your mind has to put efforts in imagining the visuals. If you keep repeat listening, it will refine the visual perceptions. As you grow and refine your perceptions, you also get benefitted by invisible therapeutic healing of body and mind. You are involved. You are active.
The next best method is to engage mind with Ramayana is, live performance. In that case, there is still a scope of imagination and refinement as the scenes are not perfect.
The worse option is modern Television and movies. Ready-made scenes. Detailed scenes. Invisible memes. Conditioning for petty selfish motives. And you passively gallop all visual perceptions. As per this research (Concentrating attention on a visual task can render you momentarily ‘deaf’ to sounds at normal levels [1]), you remain deaf (and dumb too) while you are engrossed in rich and detailed visual scenes. This eliminates auditory inspiration and stimuli to mind. Major drawback – TV watcher misses valuable चित्त शुध्धि (purification of mental imprints due to karma/actions). He or she also miss opportunity of self-realization as there is no 1 to 1 relation between the narrator (who is often considered self-realized and matured person) and the listener which is natural in traditional Ramayana recitation/narration.



Why focusing on a visual task will make us deaf to our surroundings

Concentrating attention on a visual task can render you momentarily ‘deaf’ to sounds at normal levels, reports a new UCL study funded by the Wellcome Trust

Concentrating attention on a visual task can render you momentarily ‘deaf’ to sounds at normal levels, reports a new UCL study funded by the Wellcome Trust.

The study, published in the Journal of Neuroscience, suggests that the senses of hearing and vision share a limited neural resource. Brain scans from 13 volunteers found that when they were engaged in a demanding visual task, the brain response to sound was significantly reduced. Examination of people’s ability to detect sounds during the visual demanding task also showed a higher rate of failures to detect sounds, even though the sounds were clearly audible and people did detect them when the visual task was easy.

“This was an experimental lab study which is one of the ways that we can establish cause and effect. We found that when volunteers were performing the demanding visual task, they were unable to hear sounds that they would normally hear,” explains study co-author Dr Maria Chait (UCL Ear Institute). “The brain scans showed that people were not only ignoring or filtering out the sounds, they were not actually hearing them in the first place.”

The phenomenon of ‘inattentional deafness’, where we fail to notice sounds when concentrating on other things, has been observed by the researchers before. However, this is the first time that they have been able to determine, by measuring brain activity in real-time using MEG (magnetoencephalography), that the effects are driven by brain mechanisms at a very early stage of auditory processing which would be expected to lead to the experience of being ‘deaf’ to these sounds.


Inattentional Deafness: Visual Load Leads to Time-Specific Suppression of Auditory Evoked Responses

Due to capacity limits on perception, conditions of high perceptual load lead to reduced processing of unattended stimuli (Lavie et al., 2014). Accumulating work demonstrates the effects of visual perceptual load on visual cortex responses, but the effects on auditory processing remain poorly understood. Here we establish the neural mechanisms underlying “inattentional deafness”—the failure to perceive auditory stimuli under high visual perceptual load. Participants performed a visual search task of low (target dissimilar to nontarget items) or high (target similar to nontarget items) load. On a random subset (50%) of trials, irrelevant tones were presented concurrently with the visual stimuli. Brain activity was recorded with magnetoencephalography, and time-locked responses to the visual search array and to the incidental presence of unattended tones were assessed. High, compared to low, perceptual load led to increased early visual evoked responses (within 100 ms from onset). This was accompanied by reduced early (∼100 ms from tone onset) auditory evoked activity in superior temporal sulcus and posterior middle temporal gyrus. A later suppression of the P3 “awareness” response to the tones was also observed under high load. A behavioral experiment revealed reduced tone detection sensitivity under high visual load, indicating that the reduction in neural responses was indeed associated with reduced awareness of the sounds. These findings support a neural account of shared audiovisual resources, which, when depleted under load, leads to failures of sensory perception and awareness.

SIGNIFICANCE STATEMENT The present work clarifies the neural underpinning of inattentional deafness under high visual load. The findings of near-simultaneous load effects on both visual and auditory evoked responses suggest shared audiovisual processing capacity. Temporary depletion of shared capacity in perceptually demanding visual tasks leads to a momentary reduction in sensory processing of auditory stimuli, resulting in inattentional deafness. The dynamic “push–pull” pattern of load effects on visual and auditory processing furthers our understanding of both the neural mechanisms of attention and of cross-modal effects across visual and auditory processing. These results also offer an explanation for many previous failures to find cross-modal effects in experiments where the visual load effects may not have coincided directly with auditory sensory processing.


Why Recitation of Mahakavya? The speaker–listener neural coupling



Why reciting Ramayana or listening it from loved-ones (those who are interested in your growth and self-realization progress) is any-day better than Idiot box serials and movies depicting Ramayana? (Or Mahabharata or Purana)

Information to Action ratio determines potency of mind, its ability to filter garbage from sense inputs and execute set of information fueled in for own betterment.

In oral learning traditions, due to inherent nature of minds, guide/Guru/Awakener could activate brain areas of listeners/students/Shishya in such a way that students can activate their mind at highest potency level for converting all incoming info/knowledge in action/application/experiment. And this is proved by modern science too[1]. Oral ways occupy mind in conversation, give access to live stream of information from Guru’s mind and on the fly filtration too. Here, learning is a shared activity resulting in a transfer of information across brains, from teacher to student, from speaker to listener. And overall success depends on the speaker/teacher’s ability to influence listener/student’s thought process. Modern science’ limitation is they cannot go beyond brain mirroring. Mind-space, Atma-space are alien territory for them as of now and so full potential of this method is yet untapped in our times.

Prior to visual mediums, in writing traditions, this information to action ratio was still good so that most people had a sense of being able to control some of the contingencies in their lives. What people knew about had action-value. It was valuable for them to act in life. And this is because brain still tries to process read word by mapping it to most nearest sound in memory. In addition, action-value was important factor for any type of information served.

In our visually dominated information world (See, I have to use picture! 🙂 ), this sense of potency is gradually diminishing, precisely because the whole world became the context for news/information. Everything became everyone’s business. For the first time, we were sent information which answered no question we had asked, and which, in any case, did not permit the right of reply too. With this one way traffic most of the times, in terms of passive entertainment & information titbits , it is easy for mind act impotent due to unavailability of potent catalyst and/or absence of action-value. Even if there is a chance for communication, major non-verbal communication link remains broken in virtual communication.

In this chaotic times, it is important for us to give more focus and re-training of a confused impotent mind. Train your mind to act. Act boldly. Train your mind to filter noise from information with high action-value. Face to face learning is best; whichever way suits you.



Speaker–listener neural coupling underlies successful communication

Verbal communication is a joint activity; however, speech production and comprehension have primarily been analyzed as independent processes within the boundaries of individual brains. Here, we applied fMRI to record brain activity from both speakers and listeners during natural verbal communication. We used the speaker’s spatiotemporal brain activity to model listeners’ brain activity and found that the speaker’s activity is spatially and temporally coupled with the listener’s activity. This coupling vanishes when participants fail to communicate. Moreover, though on average the listener’s brain activity mirrors the speaker’s activity with a delay, we also find areas that exhibit predictive anticipatory responses. We connected the extent of neural coupling to a quantitative measure of story comprehension and find that the greater the anticipatory speaker–listener coupling, the greater the understanding. We argue that the observed alignment of production- and comprehension-based processes serves as a mechanism by which brains convey information.



Maareecha to Mass Medium : Neural Pathway Hijacking and Nano-pollution


“The eye may be window to the soul, but neuroscientists aim to get inside and measure the interior directly. Thereís also talk about moving some walls”


First thing that clicked to me while reading this, was Maareecha राक्षस!

स रावण वचः श्रुत्वा मारीचो राक्षसः तदा || ३-४२-१४
मृगो भूत्वा आश्रम द्वारि रामस्य विचचार ह |

“And on hearing Ravana’s words demon Maareecha then became a deer and indeed ambled freely in the frontage of Rama’s hermitage. [3-42-14b, 15a]

Did you ever read the description of Maareecha as deer? Let us go through it to realize importance of what I am trying to convey.

highly splendorous and fascinating deer

मनोहरम् दर्शनीयम् रूपम्

And with hundreds of silvery stipples of body he became an astonishing deer with pleasant looks and indeed moved chewing new grass-blades of trees.

What was his motive?

प्रलोभनार्थम् वैदेह्या – to delude Vaidehi!

It is actually the last weapon Ravana used!

Mass delusion creation is the last resort for राक्षस!



Fast-forward to the time of NOW. We have Maareecha all around in form of TV, Media, News channels, Bollywood and all mass entertainment mediums. Deluding us daily!

“The eye may be window to the soul, but neuroscientists aim to get inside and measure the interior directly. Thereís also talk about moving some walls”

Yes, the time ahead is interesting. While most of us will be groomed to remain zombies, there will be bombardment of electro-chemical-magnetic medications to manipulate your neural circuits. On the other hand, there is Big data. What you already did, is recorded massively. Aggregation of such data gives fair predictions of your future actions.

Nano-pollution : To hijack and control your perceptions.

So that, we all can see only Golden Deer and ignore monster behind it.

Imagine; someone pinches you so hard that it leaves imprints with you, scar on your skin and a loud scream memory.

Now, imagine, if there is no pinch, no scream and still there are powerful imprints on your mind and memory. Call them neuro-manipulations. Sustain, if you can. Time has arrived for nano-pollution, like neuro-manipulation of your relatively raw & gullible intelligence.

What would happen if my neurons are manipulated?

Take for example : Visual pathway i.e. series of brain segments interpreting input signals and creating visual experience for you. If somehow, this highway is highjacked, then it is possible to give you controlled experience.

How to combat? Candle light march? 😉

Take back control. Do not get trapped in slavish manipulations.Greed, anger and lust : Identify them beforehand. Before it is too late.

Indian Art of Story Telling : Instructors For The World


Do you care to read Panchtantra/Ramayana/Mahabharata for your children? If you won’t, your children will miss important brain circuits’ development via recursive tales of ethics and dharma and you will be known as most stupid parents of 21st century!


If you don’t care about this part of history (Science of Tales and Fables), you will not only miss chance to reaffirm glorious past in mind and strive to reach at such summit again but you will also miss potential self-development (Physical, material and mental) which would have been possible by reading mighty poems and tales.


Hindu achievements in ethico-didactic poetry branch of literature establish once for all their intellectual superiority. It is this part of their literature that has made its way to the remotest corners of the Europe and America.

The King of Persia, Khusro Nausherawan (531-579 AD) sent his physician, Barzoi, to India in order to translate the fables of the Panchtantra from Sanskrit to Pahlavi.

The indigenous complex Bharatiya story telling, tale within tale, is greatest invention in the field of literature, connecting, rather dull bunch of words to science of brain and mind.

**** Attention for pregnant women *****:
In last trimester, maximum focus is on brain development and weight gain. In brain, new neural connections formation is happening rapidly. During this time, read Mahabhrata and Ramayana loud. Your child in the womb will get engaged in recursive tales of Maha-kavyas. This will help them to develop razor sharp memory and intellect. i.e. मेधा बुध्धि.

Why reading Ramayana and Mahabharata during pregnancy?

Many friends make fun of me or ignore my advice when I suggest them to read Mahabharata or Ramayana during pregnancy. At least for last 3-4 months of pregnancy.


Last 3 months are when brain formation happens rapidly. Last 3 months are when senses are developing to the perfection. Last 3 months are when child’s senses start their initial communication with the world.

So what?

I don’t want my child to become religious fanatic! I want him/her to be secular! 😀 सर्व धर्म समभाव!


This is nothing but utterly screwed ignorance.

Ramayana and Mahabharata are not mere stories! They are stories within stories within stories!! Like Movie inception or like movie Interstellar!

When your child in womb is introduced to such recursive tales, it stretches developing brain to the level best! Brain’s success depends upon how many connections neurons can make with each other. Recursion of tales, as it is there in most of Hindu scriptures, helps in brain development. Better the brain is developed, better it can support the mind. (Modern medicine says that mind is an outcome of brain but as per Hindu scriptures, mind is separate entity, supported by physical body i.e. brain)
