Lewis Carroll's personality and the possibility of epilepsy.

Lewis Carroll's classic Alice in Wonderland describes Alice's fantastical experiences so similarly to the actual phenomenology of the eponymous syndrome, that it has been previously suggested that Carroll himself experienced it. The syndrome is mostly associated with migrainous aura, and naturally, Carroll was postmortemly "diagnosed" as a migraineur. However, when considering his unique personality profile, it appears that he might have had temporal lobe epilepsy.

Word games and molecular recognition - The creative control of endothelial cell function.

In this paper we postulate that figures of language and structural features, which are characteristic of poetic writings and word games, have direct correlates in the cell/cell and cell/matrix recognition processes. We shall discuss the particular example of endothelial cells engagement into angiogenesis (the making of new blood vessels in adult vertebrates)-an activity that requires intense extracellular matrix (ECM) remodeling and Cell Adhesion Molecules (CAMs) rearrangement-to argue that angiogenesis controls are organized into semiotic dimensions. CAMs attach cells to the ECM; they are mainly composed of integrins (transmembrane receptors) that bind selectively to different ECM components. After ECM binding, the cytoplasmic tails of integrins within the cell will begin to interact with a wide range of recruited factors that, in turn, regulate integrin clustering in the cell membrane. These recruited factors also activate signaling pathways that link activated integrins to later microfilament system remodeling during cell migration. Ultimately CAMs work as functional protein networks-as the adaptor molecules in an organic code, the Adhesion Code-controlling cell migration/proliferation transition through the continual rearrangement of both ECM adhesion and Actin polymerization. Additionally, orchestrating the transition from clonal growth to differentiation, the interaction between CAMs and ECM components will trigger specific Signal Transduction pathways. We shall examine some attempts to conceptualize "somatic cell function" in the recent specialized literature, which introduces the notion of hierarchic organization into levels i.e. molecular, sub-cellular and cellular and describes an informational flow of increasing complexity versus decreasing number of entities through the levels. Beyond the syntactic level-the specific recognition of discrete ECM motifs by integrin heterodimers-we shall examine the semantic and pragmatic levels at which the composition and architecture of multimolecular complexes will dictate cell recognition events and cell fate decisions. These higher-level codes will be compared to the dynamics of the word games of Lewis Carroll, e.g. "doublets" and "magic squares." In such creative games words are subjected to synthetic transformations that have to conform to semantic rules, but are ultimately constrained by meaning, as concrete pragmatics. This gives us a model for analyzing angiogenesis control as a word game.

Alice in Wonderland Syndrome: A Historical and Medical Review.

Alice in Wonderland syndrome is a disorienting neurological condition that affects human perception to the senses of vision, hearing, touch, sensation, and the phenomenon of time. Individuals affected with Alice in Wonderland syndrome can experience alterations in their perception of the size of objects or their own body parts, known as metamorphopsias. It is known to occur in conditions including migraine, epilepsy, and certain intoxicants and infectious diseases. The name refers to Lewis Carrol's well-known children's book Alice's Adventures in Wonderland, in which the title character experiences alterations of sensation in which she felt that her body had grown too tall or too small, or parts of her body were changing shape, size, or relationship to the rest of her body. The syndrome was described in 1952 by Caro Lippman, and given its name in 1955 by John Todd. The metamorphopsias characteristic of this condition are also sometimes referred to as Lilliputian hallucinations, a reference to the fictional island of Lilliput in the novel Gulliver's Travels, written by Jonathan Swift in 1726. As such, many literary and medical publications have roots in the description of this syndrome. The purpose of this review is to summarize the literary and historical significance of Alice in Wonderland syndrome, as well as to provide the reader with a medical overview of the condition.

The Alice in Wonderland syndrome.

The Alice in Wonderland syndrome is a term applied to altered bizarre perceptions of size and shapes of a patient's body and illusions of changes in the forms, dimensions, and motions of objects that a patient with this syndrome encounters. These metamorphopsias arise during complex partial seizures, migraine headaches, infections, and intoxications. The illusions and hallucinations resemble the strange phenomena that Alice experienced in Lewis Carroll's Alice's Adventures in Wonderland. Charles Lutwidge Dodgson, whose nom de plume was Lewis Carroll, experienced metamorphopsias. He described them in the story that he wrote for Alice Liddell and her two sisters after he spun a tale about a long and strange dream that the fictional Alice had on a warm summer day. The author of this chapter suggests that Dodgson suffered from migraine headaches and used these experiences to weave an amusing tale for Alice Liddell. The chapter also discusses the neurology of mercury poisoning affecting the behavior of Mad Hatter character. The author suggests that the ever-somnolent Dormouse suffered from excessive daytime sleepiness due to obstructive sleep apnea.

150 years of "Alice's Adventures in Wonderland": some considerations about the Cheshire cat and neuropsychiatric phenomena / 150 anos de "Alice no País das Maravilhas": algumas considerações sobre o gato de Cheshire e fenômenos neuropsiquiátricos

Alice's Adventures in Wonderland by Lewis Carroll, pseudonym of Charles Lutwidge Dodgson, is a psychedelic dream tale apparently made for amusement. But, many speculations may be raised about its characters and phenomena created by a devout, learned and imaginative mathematician/logistician. Some issues based on the Cheshire cat due to its vanishing apparitions and its clever arguments are considered. The interpretation of the visual perception may include the "binding problem" issue. Regarding the cat's thought about inquiry, fundamental for researchers, this represents similar reasoning to that of Claude Bernard. Secondarily, some neurological and psychopathological speculations are also focused.

As aventuras de Alice no País das Maravilhas por Lewis Carroll, pseudônimo de Charles Lutwidge Dodgson, é um conto de sonho psicodélico, aparentemente feito para diversão. Mas muitas especulações podem ser levantadas sobre seus personagens e fenômenos criados por um devoto, erudito e criativo matemático/especialista em logística. São feitas algumas considerações sobre o gato de Cheshire devido suas aparições evanescentes e seus argumentos inteligentes. A interpretação sobre a percepção visual pode incluir a questão do "binding problem". Em relação ao pensamento do gato sobre a investigação, fundamental para os pesquisadores, isso representa raciocínio similar ao de Claude Bernard. Secundariamente, algumas especulações neurológicas e psicopatológicas também são apresentadas.

The Curious Connection Between Insects and Dreams.

A majority of humans spend their waking hours surrounded by insects, so it should be no surprise that insects also appear in humans' dreams as we sleep. Dreaming about insects has a peculiar history, marked by our desire to explain a dream's significance and by the tactic of evoking emotions by injecting insects in dream-related works of art, film, music, and literature. I surveyed a scattered literature for examples of insects in dreams, first from the practices of dream interpretation, psychiatry, and scientific study, then from fictional writings and popular culture, and finally in the etymology of entomology by highlighting insects with dream-inspired Latinate names. A wealth of insects in dreams, as documented clinically and culturally, attests to the perceived relevance of dreams and to the ubiquity of insects in our lives.
