What is in my head?

sketch-1554557279274

There’s a lump of stuff like blancmange or jelly inside my head, your head, and anyone who has lived on the planet.

This soggy lump controls your life, your heart, your breathing, movement, and other functions.

It also helps control the world, either personally or by electing or following what other brains think. No telepathy exists, so we only know what a brain is thinking by communication on TV, with books, in newspapers, social media and miriad ways of talking.

My pink jelly brain is mostly water. It’s surrounded by layers of protection to stop it being damaged. The pia mater and dura mater are two of these layers. It’s split into a hind brain, the most primitive part, the mid brain and two halves split between the right and left hemispheres that make up the main part of the brain. It is supplied by a ring of arteries and veins and oxygen and fluid pass from these into the brain through the blood brain barrier. Veins take away waste products back to the heart and lungs and lymphatic system.

Your brain is a tangle of synapses and neurones, nerve cells that use electrical signals to make your body move, allow you to see, talk, feel, eat. Control subconscious activities, control your organs and muscles (although research has shown that the gastric system including the stomach has its own system of nerves equivalent to the brain capacity of a rabbit).

Brains are weird. The left side of your brain controls the right side of your head and body, and vice versa. By the time you notice something has happened, it’s too late to do anything so your brain has to be able to react or predict what is happening before you even realise it.

This pinkish yellowish lump has taken us under the sea or to the top of everest. It has allowed us to go to the Moon, send probes to Mars and the planets and explore the universe with immense telescopes. It has also let us build microscopes to see microbes and even Atoms. It has even given us the skills to build machines to see inside our own brains!

Pink blobs rule! Let us just hope that people start to use them to try and bring peace and sense to the world.

      1. Yes, it’s called “The Big Bang Theory”. It’s about a group of nerdy scientists who all work at a university – think “Friends” with a geeky twist. It’s one of my most favourite TV shows ever. Sheldon, the guy in the clip, is very clever but socially inept. I find it very funny indeed.
