The brain is something I wish I knew more of. And this morning I'm left in awe at just how clever it is. An adult human brain weighs between 1 and 1.5 kilograms (Southampton pikeys appear not to be included in that average), however when suspended in the dense cerberospinal fluid (CSF) that protects the brain, it weighs roughly 50 grams.

Not only does CSF surround the brain, but it also protects the internals of the brain in all the ventricles, too. It is also, as name suggests, found in the spinal column. It's there to protect the nerves from the surrounding bones, the skull and vertebrae.

Your body produces 500ml of CSF in a single day, but what I find fascinating is that in the event of traumatic injury to the brain or spinal column such as a road accident, the body responds by producing more of this fluid. Too much CSF, however can cause increased pressure and permanent damage to the things it protects.

A little unrelated, but interesting nonetheless; At birth the humans skull is rather soft and it is sized as large as it can without causing undue peril on the mother during birth. As the child travels(?) through the birth canal, the skull is squashed and deformed. On birth, it then pops back into shape.

Another amazing thing about the brain is the whole issue of self-control of emotions. For example when feeling anger or upset at someone but trying not to lash out or be abusive, the brain is feeling one strong emotion, but at the same time trying to overcome this emotion. The whole way that emotions refer to each other, internally to the brain is outstanding. And it adds a nice twist to realise that I'm creating an emotion in my brain whilst I ponder about emotions "thinking" about themselves. Mad!

Which leads me, vaguely, on to what I really wanted to say... I was woken up this morning by a text message at about 08:10. I distinctly remember my dream at that point. I know where I was, who I was with and I can see the picture perfectly vividly. After reading the text and popping to the loo, I went back to sleep.

I was again woken, but this time by the post coming through the door. And again I remember the dream I was having very well. Although this time, it wasn't graphical, there were no images. I was on a telephone call to someone (and I know who it was). But I had invented an entire personality for them. I was having a telephone conversation with another character I had plucked out of the air and given life to.

Any how, I know I always find reading about other peoples dreams so boring, so I'll stop now. But I hope someone appreciates the stunning beauty of the brain I'm feeling this morning.

And to leave you with something. The story that we only use 10% of our brains... it's false.
