Many neurosurgeons are now persuaded that thinking is hormonal and that it takes place all over the body. This could explain why scientists have never been able to find the anatomical site of memory. Hormones affect behaviour and thinking. For example, tests have shown that the brain thinks differently if the gonads are removed. Chemical analysis of the brains of suicide victims have shown hormonal profiles different from those of normal people.
Extreme rages floods the brain with hormones that significantly affect behaviour.
Opiate-like hormones such as endorphin and encephalin are produced by the brain and are responsible for the intense pleasure associated with sexual orgasm. Scientists have now identified 45 different hormones that are associated with behaviour such as sleep, sorrow, fear, peace, pain, obesity, arthritic stiffness, addiction, hunger, depression and stress. Unequivocal evidence has been produced to show that the immune system, which defends the body against diseases, is influenced by mental events. Anger at those making demands on you. Self-criticism for putting up with the demands.
