Is a thought simply the sum total of the activity of all the neurons in the brain? No, just as a message is not simply the placement of a sequence of letters which follow the rules of grammar. How do those letters stand in relation to that message? How does the activity of neurons stand in relation to a thought? Was Descartes right, or are we our brain?
Let the sunshine in
How would we manage, if we could not visualise three-dimensional objects from flat two-dimensional diagrams? An amazing feat our brain performs. What role does pre-determined programming play in this? That is related to how the sun shines on us.

Everybody wants fast acting psychotropics, but that is not possible for most psychiatric disorders.
But integration of pharmacotherapy and psychotherapy can be extremely rewarding.
Who directs the brain?
Our brain controls everything we do and think and what happens in our body. Who directs these complicated brains? “I” do? No, there is no central power or police force, no editor, prime minister or CEO, no leader. The brain controls all without a director.
The basis for most of the severe mental disorders is clear
