Organoids. Brain waves. Death…

Some years ago, two hundred and fifty miles over Alysson Muotri’s head, a thousand tiny spheres of brain cells were sailing through space. The clusters, called brain organoids, had been grown a few weeks earlier in the biologist’s lab here at the University of California, San Diego. He and his colleagues altered human skin cells into stem cells, then coaxed them to develop as brain cells do in an embryo.

The organoids grew into balls about the size of a pinhead, each containing hundreds of thousands of cells in a variety of types, each type producing the same chemicals and electrical signals as those cells do in our own brains.

What, exactly, were they growing into? That was a question that had scientists and philosophers alike scratching their heads.

Dr. Muotri and his colleagues reported that they had recorded simple brain waves in these organoids. In mature human brains, such waves are produced by widespread networks of neurons firing in synchrony. (1)

Brains observing other brains.

Fascinated by what they see.

A world full of light.

A world full of shadows.

Do not try so much to stay awake.

You are meant to sleep. And dream.

Of a cosmos somewhere else.

A cosmos casting shadows over shadows.

Which generates no brain waves to detect.

An invisible cosmos.

Penetrating this one.

Through all the brains and brain waves.

Yes, you can detect the waves some-How.

But it is the Why which makes you doubt if that really means something…

Do your brain waves mean anything?

Do you dare question yourself?

Listening to music. Humans. Apes.

In the eternal search for understanding what makes us human, scientists found that our brains are more sensitive to pitch, the harmonic sounds we hear when listening to music, than our evolutionary relative the macaque monkey. The study, funded in part by the National Institutes of Health, highlights the promise of Sound Health, a joint project between the NIH and the John F. Kennedy Center for the Performing Arts that aims to understand the role of music in health.

“We found that a certain region of our brains has a stronger preference for sounds with pitch than macaque monkey brains,” said Bevil Conway, Ph.D., investigator in the NIH’s Intramural Research Program and a senior author of the study published in Nature Neuroscience. “The results raise the possibility that these sounds, which are embedded in speech and music, may have shaped the basic organization of the human brain.” (1)

Yes, we are the only ones listening to music.

Because our mind is never here.

We love traveling to the stars.

Only because we detest the Earth on which we were born.

We will learn one day.

When we reach the stars.

That those bright small dots we will see.

Is our home.

Which we have left a long time ago…

Learning. Remembering. Crying.

Scientists have revealed the structure of a critical receptor in the brain associated with learning, memory, behavior and mood. The new research is the first to reveal the structure of AMPA receptors in their natural state. This discovery could lead to new insight about the mechanism behind a wide range of nervous system disorders and diseases. (1)

Humans wandering in the cosmos.

Learning things.

Remembering things.

Changing moods.

Trying to find a clearing in a forest full of life.

Feeling anxious. Alone. Sad.

There was a time when we felt nothing.

When there was nothing to learn.

Nothing to remember.

No receptors.

For we were there ones who omitted knowledge.

We were the ones who made things memorable.

Bridging the Gap between death and life.

Between being and existing.

Everything is wet.

But there is no rain falling.

Empty forest.

Can you feel it?

Tears down your cheek…

Learning. Remembering. Crying.

When looking at a picture of a sunny day at the beach, we can almost smell the scent of sun screen. Our brain often completes memories and automatically brings back to mind the different elements of the original experience. A new study now reveals the underlying mechanisms of this auto-complete function.

The researchers made an exciting discovery: During memory recall, neurons in the hippocampus fire strongly. Additionally, neurons in the entorhinal cortex began to fire in parallel to the hippocampus. According to one researcher “The act of remembering put neurons in a state that strongly resembles their activation during initial learning.” (1)

We know what we should see.

And we see it.

We know what we should smell.

And we smell it.

But we know nothing…

And yet…

What a lovely rose…

Dipped in the ocean of the moonlight.

Can you feel the breeze?

Isn’t it strange that you don’t miss the warmth of the sun?
