Sobre las investigaciones neuro-embriológicas cajalianas: la correspondencia entre Santiago Ramón y Cajal y Wilhelm His

Abstract

[ES] Se presenta y edita, con su correspondiente aparato crítico, la correspondencia mantenida entre Santiago Ramón y Caja1 (1852-1934) y Wi1helm His (1831-1904), que abarca el periodo comprendido entre los años 1890 y 1893. Se trata de una serie de seis cartas -las únicas que se conservan- remitidas entre ambos científicos que ilustran lo que puede considerarse como la primera etapa de la obra neuro-embriológica cajaliana. En dicha etapa, las observaciones sobre el desarrollo de las prolongaciones nerviosas derivaron directamente de la utilización del método ontogénico, la utilización de embriones o animales jóvenes para la visualización de elementos celulares nerviosos y la comprobación de su independencia. Resultado de estas investigaciones fue la descripción del denominado «cono de crecimiento», estructura apical de las prolongaciones neuronales que por elongación determina el crecimiento.

[EN] They're now being published, with their complementary comments and notes, the mail mantained between Santiago Ramón y Cajal (1852-1934) and Wilhelm His (1831-1904). The letters were written between 1890 and 1893. Only six letters have survived in time and they ilustrate what we can consider the first stage in neuro-embryological works of Cajal. At that stage, the experiments and observations of the neuronal prolongations developement directly lead to the use of the ontogenic method, that is, the use of embryons or young animals to view the neuronal cells and the verification of their independence. The consequences of the experiments were the description of the phenomenon known as «growing cone».
