A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
I'm using the afterlife as a backdrop against which to explore the joys and complexities of being human - it turns out that it's a great lens with which to understand what matters to us.
Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.
I think what a life in science really teaches you is the vastness of our ignorance.
People wouldn't even go into science unless there was something much bigger to be discovered, something that is transcendent.
The same stimuli in the world can be inducing very different experiences internally and it's probably based on a single change in a gene. What I am doing is pulling the gene forward and imaging and doing behavioural tests to understand what that difference is and how reality can be constructed so differently.
