The Man Who Tasted Shapes is a book by neurologist Richard Cytowic about synesthesia.

Contents

Summary

The book is divided into two parts. In the first part, Cytowic describes his chance encounter during a dinner party on February 10, 1980 with MW, the "Man Who Tasted Shapes." Cytowic describes how his host reported that "There aren't enough points on the chicken!" [1] and how this chance comment led to Cytowic's investigations of the neurological phenomenon of synesthesia. Early chapters include background information on how the brain is organized, drawn mainly from Paul D. MacLean's Triune Brain theory. Cytowic describes MW's synesthesia, noting the consistency of his reports, that such experiences are "generic" and consistent over time. [2] Chapters dealing with more scientific theories, data and experimentation are alternated with autobiographical and more personal chapters describing the historical details of Cytowic's investigations into synesthesia.

In order to explore the biological basis of synesthesia, Cytowic describes experiments in which he tested how MW's synesthesia was reduced by MW's daily routine of stimulants such as nicotine and caffeine and depressants such as alcohol. [3] In more intensive investigations of the effects of different psychoactive substances, Cytowic notes that stimulants, including a dose of amphetamine, decreased the strength of MW's synesthesia, while amyl nitrite increased the strength of MW's synesthesia. [4] For example, MW reports that mint feels like a cool glass column, but that amyl nitrite led him to feel as if he were placing his hand among many glass columns. [5] Cytowic also summarizes work done with functional neuroimaging which showed unusually low cortical activation in MW. Based on these results, Cytowic proposes a theory in which synesthesia is a result of unusual processing in the limbic system and an overall decrease in cortical activation. [6]

In later chapters, Cytowic reports on his efforts to make synesthesia more widely known, on the experiences of many other synesthetes who have contacted him, and how synesthesia affects their lives. Cytowic describes how an article about his work on synesthesia in the tabloid The National Enquirer , a publication which is "not known to help one's career", [7] led to his first contacts with synesthetes beyond MW [8] These personal accounts of synesthesia, described here in more autobiographical style, also form the basis of Cytowic's more detailed scientific book, Synesthesia: A Union of the Senses. Additionally, Cytowic discusses the links between synesthesia and memory, as first noted in Alexander Luria's book The Mind of Mnemonist about Solomon Shereshevskii, a Russian mnemonist who also experienced fivefold synesthesia. [9]

In the second part of the book, entitled "Essays on the Primacy of Emotion", Cytowic presents a number of his reflections on what the phenomenon of synesthesia means for traditional neuroscientific and neurological practice, how anomalous findings can lead to major scientific discoveries, and the role that emotion plays in our understanding of the world around us.

Amyl nitrite is a chemical compound with the formula C5H11ONO. A variety of isomers are known, but they all feature an amyl group attached to the nitrite functional group. The alkyl group is unreactive and the chemical and biological properties are mainly due to the nitrite group. Like other alkyl nitrites, amyl nitrite is bioactive in mammals, being a vasodilator, which is the basis of its use as a prescription medicine. As an inhalant, it also has a psychoactive effect, which has led to its recreational use, with its smell being described as that of old socks or dirty feet. It is also referred to as banapple gas.

The clavier à lumières, or tastiera per luce, as it appears in the score, was a musical instrument invented by Alexander Scriabin for use in his work Prometheus: Poem of Fire. Only one version of this instrument was constructed, for the performance of Prometheus: Poem of Fire in New York City in 1915. The instrument was supposed to be a keyboard, with notes corresponding to colors as given by Scriabin's synesthetic system, specified in the score. However, numerous synesthesia researchers have cast doubt on the claim that Scriabin was a synesthete.

The title mnemonist refers to an individual with the ability to remember and recall unusually long lists of data, such as unfamiliar names, lists of numbers, entries in books, etc. Some mnemonists also memorize texts such as long poems, speeches, or even entire books of fiction or non-fiction. The term is derived from the term mnemonic, which refers to a strategy to support remembering, but not all mnemonists report using mnemonics. Mnemonists may have superior innate ability to recall or remember, in addition to relying on techniques.

Synesthesia is a neurological condition in which two or more bodily senses are coupled. For example, in a form of synesthesia known as grapheme-color synesthesia, letters or numbers may be perceived as inherently colored. Historically, the most commonly described form of synesthesia has been between sound and vision, e.g. the hearing of colors in music.

Lexical–gustatory synesthesia is a rare form of synesthesia in which spoken and written language causes individuals to experience an automatic and highly consistent taste/smell. The taste is often experienced as a complex mixture of both temperature and texture. For example, in a particular synaesthete, JIW, the word jail would taste of cold, hard bacon. Synesthetic tastes are evoked by an inducer/concurrent complex. The inducer is the stimulus that activates the sensation and the taste experience is the concurrent.

The phrase synesthesia in art has historically referred to a wide variety of artists' experiments that have explored the co-operation of the senses in the genres of visual music, music visualization, audiovisual art, abstract film, and intermedia. The age-old artistic views on synesthesia have some overlap with the current neuroscientific view on neurological synesthesia, but also some major differences, e.g. in the contexts of investigations, types of synesthesia selected, and definitions. While in neuroscientific studies synesthesia is defined as the elicitation of perceptual experiences in the absence of the normal sensory stimulation, in the arts the concept of synaesthesia is more often defined as the simultaneous perception of two or more stimuli as one gestalt experience. The usage of the term synesthesia in art should, therefore, be differentiated from neurological synesthesia in scientific research. Synesthesia is by no means unique to artists or musicians. Only in the last decades have scientific methods become available to assess synesthesia in persons. For synesthesia in artists before that time one has to interpret (auto)biographical information. For instance, there has been debate on the neurological synesthesia of historical artists like Kandinsky and Scriabin. Additionally, Synesthetic art may refer to either art created by synesthetes or art created to elicit synesthetic experience in the general audience.

Synesthesia is a neurological condition in which two or more bodily senses are coupled. For example, in a form of synesthesia known as Grapheme → color synesthesia, letters or numbers may be perceived as inherently colored. In another, called number → form synesthesia, numbers are automatically and consistently associated with locations in space. In yet another form of synesthesia, called ordinal linguistic personification, either numbers, days of the week, or months of the year evoke personalities. In other forms of synesthesia, music and other sounds may be perceived as colored or having particular shapes. Recent research has begun to explore the neural basis of these experiences, drawing both on neuroscientific principles and on functional neuroimaging data.

Fictional works that have main characters with synesthesia and non-fiction books to non-specialist audiences reflect the condition's influence in popular culture and how non-synesthetes view it. Synesthesia is a neurological condition in which one or more sensory modalities become linked. However, for over a century, synesthesia has also been the artistic and poetic devices that try to connect the senses.

<span class="mw-page-title-main">Chromesthesia</span> Sound to color synesthesia

Chromesthesia or sound-to-color synesthesia is a type of synesthesia in which sound involuntarily evokes an experience of color, shape, and movement. Individuals with sound-color synesthesia are consciously aware of their synesthetic color associations/perceptions in daily life. Synesthetes that perceive color while listening to music experience the colors in addition to the normal auditory sensations. The synesthetic color experience supplements, but does not obscure real, modality-specific perceptions. As with other forms of synesthesia, individuals with sound-color synesthesia perceive it spontaneously, without effort, and as their normal realm of experience. Chromesthesia can be induced by different auditory experiences, such as music, phonemes, speech, and/or everyday sounds.

Synesthesia is a neurologically based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. There are many occurrences of synesthesia in books, television and film.

Exceptional memory is the ability to have accurate and detailed recall in a variety of ways, including hyperthymesia, eidetic memory, synesthesia, and emotional memory. Exceptional memory is also prevalent in those with savant syndrome and mnemonists.

<span class="mw-page-title-main">Synesthesia</span> Neurological condition involving the crossing of senses

Synesthesia or synaesthesia is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway. People who report a lifelong history of such experiences are known as synesthetes. Awareness of synesthetic perceptions varies from person to person. In one common form of synesthesia, known as grapheme–color synesthesia or color–graphemic synesthesia, letters or numbers are perceived as inherently colored. In spatial-sequence, or number form synesthesia, numbers, months of the year, or days of the week elicit precise locations in space, or may appear as a three-dimensional map. Synesthetic associations can occur in any combination and any number of senses or cognitive pathways.

<i>Wednesday Is Indigo Blue</i>

Wednesday Is Indigo Blue: Discovering the Brain of Synesthesia is a 2009 non-fiction book written by Richard Cytowic and David Eagleman documenting the current scientific understanding of synesthesia, a perceptual condition where an experience of one sense causes an automatic and involuntary experience in another sense. The afterword is written by Dimitri Nabokov, a synesthete, and the son of the well-known author and synesthete Vladimir Nabokov.

<span class="mw-page-title-main">Ideasthesia</span> Phenomenon in which concepts evoke sensory experiences

Ideasthesia is a neuropsychological phenomenon in which activations of concepts (inducers) evoke perception-like sensory experiences (concurrents). The name comes from the Ancient Greek ἰδέα and αἴσθησις, meaning 'sensing concepts' or 'sensing ideas'. The notion was introduced by neuroscientist Danko Nikolić as an alternative explanation for a set of phenomena traditionally covered by synesthesia.

Mirror-touch synesthesia is a rare condition which causes individuals to experience a similar sensation in the same part or opposite part of the body that another person feels. For example, if someone with this condition were to observe someone touching their cheek, they would feel the same sensation on their own cheek. Synesthesia, in general, is described as a condition in which a concept or sensation causes an individual to experience an additional sensation or Synesthesia is usually a developmental condition; however, recent research has shown that mirror touch synesthesia can be acquired after sensory loss following amputation.
