El trabajo trata sobre el problema brain to brain, o comunicación entre mentes a través de una interfaz tecnológica cerebro-máquina. Se trata de un estudio teórico de neurociencia cognitiva donde se analiza el problema, se bosquejan soluciones y se evalúan sus plausibilidades. Al inicio, se presenta el problema en el marco de la “telepatía tecnológica”, referida a la posibilidad de decodificar contenidos mentales de un sujeto a través de un sistema artificial. Se destaca que el problema brain to brain refiere no solo a lo anterior, sino a la posterior encodificación del contenido en un sujeto receptor. Se trataría entones de un doble proceso de de lectura y escritura mental mediatizado por neurotecnología. Se discute luego el carácter rudimentario de los modelos teórico-experimentales desarrollados hasta ahora, a los que se categoriza como pseudo soluciones por circunscribirse a un nivel subléxico. Finalmente, se propone dos posibles soluciones teóricas de distinto alcance y plausabilidad, que se ajustarían mejor a una auténtica comunicación brain to brain. La primera, refiere a la posibilidad de encodificar grafemas en un sujeto receptor. La segunda, más conjetural, refiere a la encodificación de unidades semánticas derivadas de un alfabeto artificial ad hoc. Al respecto, se esbozan sus características.

It is a theoretical study of cognitive neuroscience where the problem is analyzed, solutions are outlined and their plausibility is evaluated. To begin with, the problem is presented within the framework of “technological telepathy”, which refers to the possibility of decoding mental contents of a subject through an artificial system. It is emphasized that the brain to brain problem refers not only to what was previously stated, but also to the subsequent encoding of the content in a recipient subject. It would then be a double process of mental reading and writing mediated by neurotechnology.The rudimentary nature of the theoretical-experimental models developed until now is discussed, they are categorized as pseudo solutions to be circumscribed to a sub-lexical level. Finally, we propose two possible theoretical solutions of different scope and plausibility, which would be better adjusted to an authentic brain to brain communication. The first one refers to the possibility of encoding graphemes in a recipient subject. The second, more conjectural, refers to the encoding of semantic units derived from an artificial ad hoc alphabet. In this regard, its characteristics are outlined.
