The story goes something like this.
A few years ago, a group of scientists from the University of Oxford began using MRI scanners to track brain activity while listening to recordings of human speech.
When the team looked at a person’s brain activity as they were reading a story, they found that the brain activity of people reading a creepy story was about twice as loud as the brain’s activity when they were listening to a cute story.
The researchers, led by Oxford neuroscientist and professor of neurobiology Michael Ewen, noticed something odd about this pattern: The more a person read a creepy sentence, the louder the brain responses became.
This was because the more people read a scary story, the more neurons in the brain responded to it, as if the story was making the person’s nervous system twitch.
The team then decided to test whether reading scary stories actually causes the nervous system to become more active.
To do this, they recruited volunteers to watch a short video of a child singing.
The children were then asked to rate how loud they thought the song sounded.
The video showed that, in particular, the children in the video thought the children singing were singing at a loud volume.
So, they decided to take a different approach.
Instead of just listening to the video of the child singing, they recorded the sound of the children themselves singing in a similar way.
They played the recording of the song on their computers and asked people to rate it, so that they could know if the children were singing louder or quieter than they really were.
The volunteers then listened to the recording again.
When they did so, they noticed that their brain activity seemed to increase in response to the children’s singing, even though the children actually weren’t actually singing at all.
This suggests that the activity in the childrens’ brains was actually just a response to their own vocalisations, and not actually the vocalisations themselves.
In other words, the activity was just a side-effect of the way the brain was processing the audio.
It was only after the researchers played the recordings of the two groups of people singing that they realised that the children they were hearing were actually singing louder than the recordings they were watching.
This led to the theory that the human brain was singing at the same volume as the children, and this would lead to a greater degree of activity in response.
This is a fascinating result.
It suggests that it’s possible to tune the brain to what we like and what we don’t like, and that the process of tuning can happen even when you’re not listening to an audio source.
It also suggests that we have a very good sense of what a good experience is like, as long as we’re not consciously tuning in to the sound.
The results are important because, in humans, it is possible to hear the sound we like, or to detect the sound you like.
In the case of the singing children, they were able to hear exactly what the researchers were tuning the brain in response towards, as the researchers said.
So this new finding is exciting, but not all that surprising.
There are lots of other studies that have used similar methods to measure how our brains respond to sounds, and it’s quite likely that a similar process is going on here.
The key is that the results are robust enough that they can be tested in a lab.
The Oxford team say that, if they can get a good sample of the human auditory system to respond in this way, it could potentially help us to understand how we hear and hear loud, for example, how we’re able to distinguish the sounds of birds from the sounds that are made by cars.
That would be exciting.
