Alternate virtual worlds.

Synesthesia is a sui generis neurological condition, that impregnates the letters of the alphabet with sorts and types of personality. Each letter represents a different human personality: A: is a very sensible mother, I: a small individual, H and G: demanding people, M and N: 2 old ladies who spend their time, chatting, T: a protective male. The days of the week and the months of the year also evoke personalities. The one affected of synesthesia, see letters and numbers colored and associate shapes to flavors. In certain type of synesthesia (grapheme → color), letters and numbers are perceived inherently colored. Some people have preferences by certain colors associated to each letter: A = red, O = white or black, S= yellow (Day, 2005). In the space sequence, the months of the year and/or days of the week obtain precise space locations (1980 can be far away than 1990), or to have a three-dimensional vision of 1 year, in form of a map that turns in the sense of the needles of a clock or, to the inverse one. The understanding of the language of the synesthésics is strange, not adapting to the well-known, in as much as it is desusual to see music or colored flav0rs. Its prevalence, has been estimated in 1 x each 23 people (Simner et al. 2006). Although not yet one know if it is hereditary, it is common to associate synesthesia to psyquedélic drugs ingestion, stroke or as a result of blindness or deafness.


Using a variation of the MRI (diffusion tensile imaging), Romke Rouw and collaborator (University of Ámsterdam), have demonstrated hyperconnectivity -2 sensorial body connections between brain areas (gyrus fusiform, in charge of perceptions and an area near it in charge of categorizacion of visual stimuli). Rown distinguishes subsets, existing people who see colors in their inner world, counting on few connections in comparison to synesthesics that project their colors towards the outer world. Fortunately synesthesia, absolutely non cause damage and Julia Simner, suggests that all of us can have something of it. Some researchers have suggested that in synesthesia exists an insufficiency of the process of normal adjustment to outer and inner sensations or perhaps a reduction in the inhibition of sensorial control mechanisms (Grossenbacher & Lovelace 2001), in which case the signals coming from multiple multisensorial stages could have influence in early stages of processing, activating cortical visual areas in synesthesics but that in non sysnesthesics. For us (Alucinogenos, UPCH, Peru, 1997), the present normal representation of the internal and external world (conscience/biological multimedia, for us), has been conditionated by the evolution. In this instance, the maintaining of the status quo is carried out connecting multiple cerebral areas with the aid of well-known chemical neurotransmissors. When the humans ingest substances similar to these neurotransmissors (harmina, LSD, mescaline), habitual humans, are discovered total or partial alternative steps to the normal representation of the external and internal world, with perceptions obvious gone off of the normal general scheme. As to maintain the normal scheme is an arduous task, synesthesias are frequent, although fleeting, self-reparables and at the same time correctable technically. The study of this phenomenon could help to understand the animal mind animal and to create artistic alternating or futuristic worlds.


Mundos alternos virtuales

Sinestesia es una condición neurológica sui generis, que impregna las letras del alfabeto con géneros y tipos de personalidad. Cada letra del alfabeto representa una personalidad humana distinta :A es una madre muy sensible, I : un individuo pequeño, H y G : personas exigentes, M y N : 2 viejas señoras que pasan su tiempo juntas, charlando, T: un macho protector. Los dias de la semana y los meses del año también evocan personalidades. Los afectos de sinestesia, ven letras y numeros coloreados y asocian formas a sabores. En cierto tipo de sinestesia (
grapheme → color), cartas y numeros son percibidos inherentemente coloreados. Algunos personas tienen preferencias por ciertos colores asociados a cada letra : A = rojo, O = blanco o negro, S= amarillo (Day, 2005). En la secuencia espacial, los meses del año y/o dias de la semana logran localizaciones precisas espaciales (1980 puede ser mas lejos que 1990), o tener la visión tridimensional de 1 año, en forma de un mapa que gira en el sentido de las agujas de un reloj o, a la inversa. La comprensión del lenguaje de los sinestésicos es extraña, no adaptandose a lo conocido, en tanto es desusual ver música o colorear olores. Su prevalencia, ha sido estimada en 1/x cada 23 personas (Simner et al. 2006). Aunque aún no se ha precisado si es hereditaria, es común asociar la sinestesia a ingesta de drogas psiquedélicas, accidentes cerebrovasculares o a consecuencia de ceguera o sordera .


Empleando una variación del MRI (diffusion tensor imaging), Romke Rouw y colaboradores (Universidad de Ámsterdam), demostraron recientemente hiperconectividad -2 o mas sentidos corporales acoplados- entre areas cerebrales (gyrus fusiforme, comprometido en la percepción y un area cercana a ella en la categorizacion de estimulos visuales). Rouw distingue subsets, existiendo personas que ven colores en su mundo interior, contando con pocas conexiones en comparación a sinestesicos que proyectan sus colores hacia el mundo exterior. Por fortuna la sinestesia, no causa daño en absoluto y Julia Simner, sugiere que todos podemos tener algo de ello. Algunos investigadores han sugerido que en la sinestesia existe una insuficiencia del proceso de ajuste normal de las sensaciones exteriores o, una reduccion en la inhibición de los mecanismos de control sensorial (Grossenbacher & Lovelace 2001), en cuyo caso las señales procedentes de multiples estadios multisensoriales podrian influenciar estadios tempranos de procesamiento, activando areas corticales visuales en sinestesicos mas que en no sisnestesicos. Para nosotros (Mechan Mendez Victor: Alucinógenos, UPCH,Peru,1998), la representación normal actual del mundo interno y externo (conciencia/multimedia biológica, para nosotros), ha sido condicionada por la evolucion. En ultima instancia esta, mantiene el status quo conectando múltiples areas cerebrales con neurotrasmisores conocidos. Cuando los humanos ingieren sustancias similares a los neurotrasmisores (harmina, LSD, mescalina), habituales humanos, se descubren pasos alternativos totales o parciales a la representación normal del mundo externo e interno, con percepciones obviamente desentonadas del esquema general normal. Como mantener el esquema normal es una tarea ardua, las sinestesias son frecuentes, aunque al mismo tiempo fugaces, autoreparables y corregibles tecnicamente. El estudio de este fenómeno podria ayudar a entender la mente animal y crear mundos alternos artisticos o, futuristas.
