We have learned a little about how the mind works. We can name the neurons and other cells and study the chemical signals that connect the cells.
We have learned that certain chemicals affect our feelings, from alcohol and cocaine we can alter the machinery of the mind by changing the way the signal molecules between cells work. That is the basis for Prozac, which affects the turnover of a signal molecule called serotonin.
One reason we overeat is because eating also changes serotonin behavior subtly, giving us a subliminal “high.”
But these insights into the way the brain works barely touch the surface of the complexity. Nothing we know begins to address how the transmission of impulses can turn into an idea.
Do you wonder what a thought is made of? What is a memory?
