Have you ever heard about symbols and sounds or music inherently associated with colors? Have you ever heard about people who always dream in color, see sounds or hear colors, odors, and who cannot dissociate days of week, months, numbers and letters from specific colors? This phenomenon is real and called synesthesia. It can be literary, scientific, and/or cognitive. It is analyzed within the framework of symbolism and neuroscience. It takes place in the left hemisphere of the human brain and the neo-cortex. It is activated by the limbic system and the tangling of two or more synapses. In this book, I aspire to reflect on this phenomenon under the auspices of symbolism and neuroscience. However, I will emphasize the literary aspect of synesthesia (synesthesia as a metaphor) while pondering on symbolism as a general trend along with its scientific and cognitive aspects.
