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.

Our internal life and external actions are steered by biological coctails to which we have neither immediate access nor direct acquaintance.

Just give the brain the information and it will figure it out.

I spent my adult life as a scientist, and science is, essentially, the most successful approach we have to try and understand the vast mysteries around.

Neuroscience over the next 50 years is going to introduce things that are mind-blowing.

The left hemisphere acts as an "interpreter," watching the actions and behaviors of the body and assigning a coherent narrative to these events.
