How complicated is the brain?

The brain is a complex organ. Even in something as small as a fruit fly (whose brains are mapped in the image above). Yet…

Scientists from Google and the Janelia Research Campus in Virginia have published the largest high-resolution map of brain connectivity in any animal, sharing a 3D model that traces 20 million synapses connecting some 25,000 neurons in the brain of a fruit fly.

The model is a milestone in the field of connectomics, which uses detailed imaging techniques to map the physical pathways of the brain. This map, known as a “connectome,” covers roughly one-third of the fruit fly’s brain. To date, only a single organism, the roundworm C. elegans, has had its brain completely mapped in this way.

It’s a fascinating story of both biology and computer science. (It takes a lot of computing power to do this). For more details, see: Google publishes largest ever high-resolution map of brain connectivity – The Verge

It’s Wednesday. Your brain is tired. Maybe you need to feed it better.

And by feed it I don’t mean drink more coffee. I mean eat foods that have been shown to help our brains work better. The author of this piece ate food considered best for our brains for a week and recorded what happened. Surprise: you don’t turn into a genius. But you will see some benefits. And that’s a good thing.

Your brain is dirty. There’s only one way to clean it

Sleep. At least according to this:  ‘Waves’ of fluid clear the brain of toxins during sleep, say researchers – Big Think.

When you sleep, your brain is designed to wash away toxic chemical buildup in your brain. If that toxic buildup is allowed to stick around (due to lack of sleep), bad things happen to your brain and you.

So clean your brain. Get some sleep. See the article to understand more of this.

Not all mindfulness is the same


If you think all mindfulness is the same, then read this: Different Types Of Meditation Change Different Areas Of The Brain, Study Finds.

Key quote:

a new study from the Max Planck Institute finds that three different types of meditation training are linked to changes in corresponding brain regions. The results, published in Science Advances, have a lot of relevance to schools, businesses and, of course, the general public.

Mindfulness can be helpful for many reasons. But how you pursue it can yield different results. Something to keep in…mind.

It’s Monday. Your brain is barely functioning. Great news! You don’t need it!

Damaged brain due to fluid

You might think I am joking but I am not.

Take a look at the photo above. This is a scan of a living man’s brain: the black part is fluid, while the part around the black part is his remaining brain. Essentially 90% of his brain has been displaced by the fluid. And yet he was considered a functioning person, despite only have 10% of a brain mass most people have.

The story behind the scan and the questions that it raises is in this article: A civil servant missing most of his brain challenges our most basic theories of consciousness.

Fascinating. Perhaps in a few years / centuries we will understand how the brain works. For now we are mostly clueless, much like you are while you wait for your coffee to kick in. 🙂
