Psychophysiology is an ambitious science that seeks to navigate between the pitfalls of behaviorism and psychoanalysis. In attempting to bridge the material nature of the world with human consciousness, it must ground itself in the only solid foundation for the study of human behavior: the brain itself.

The brain is not simply a material mass of a certain volume and weight, but an expansive labyrinth of functions, the interpretation of which has often eluded leading representatives of philosophy and science. However, in recent decades, there have been astonishing advances in the science of studying the brain, which serves as the organ of thought and will.

The new knowledge about brain function often renders naive the views that external reality is automatically reflected in the brain and our thoughts. Scientific advancements in neuropsychology and psychophysiology, along with methods from cognitive sciences, foster optimism that their findings will be able to better address the unresolved questions about the nature of humanity and the formation of consciousness.
