In Our Head Facts- Fatty Fatty Brain

Consisting of at least 60% fat, the human brain is the fattest organ in the whole body.

What’s more, the fat cimgresontained in the brain cannot be metabolised for energy. The brain does not contain “fat cells”, such as those in our belly that mercifully shrink when energy is scarce, but rather fatty acids known as “lipids”.

Lipids form the “myelin sheath” which insulates the wires leading to and from neurons. In this way “brain fat” functions to insulate brain wiring allowing electrical messages to be carried effectively and efficiently throughout the nervous system.

So next time you’re having a good think, you can thank fat for that.

When The Brain Stops- Aaron Freeman

I’ve emphasised again and again how critical a functioning brain is for human behaviour and, of course, life. While there’s still very little known about the root and run of the conscious mind, ideas purposed by leading theorists, many findings from the cognitive sciences, even the very title of this blog, strongly suggest that personality and consciousness are products of the functioning brain, that all there is to us is the neural cogs, wheels and connections residing inside our head.

When considered in light of the inevitable brain death waiting at the end of our days this makes for rather morbid reading. When our neurons stop signalling, our neural structures start shrinking, when our cerebral cogs quit connecting and our cognitive wheels stop spinning…mustn’t our presence on earth also end?

Not so. And the following speech by American comedian and journalist Aaron Freeman eloquently conveys why this is the case.

Freeman’s words about why you should have a Physicist speak at your funeral, make up the most moving piece of pros I’ve ever read, or heard, relating to the world post brain activity. No matter your religious beliefs, or lack thereof, this piece will move you, it will reassure you, it will teach you that not only did your very presence change the world, but it will continue to do so. It will enlighten you as to how you, your family members, your friends, your favourite musicians, poets and playwrights, how we all continue to be when the brain no longer speaks.

I couldn’t but share…
