Capítulo VIII: La Edad Media. Luego de la época Galénica hubo una especie de “breve pausa” en el avance del conocimiento anatómico, que duro cientos de años. Esto se debió a múltiples factores (entre ellos al propio Galeno), que veremos brevemente. Los escritos anatómicos, fisiológicos y médicos...
While civilizations other than the Egyptians may have had some knowledge of neurological diseases (modern neurology and psychiatry), and of the form and function of the nervous system (anatomy and physiology, respectively), there are virtually no records of these. There are indirect indications that the...
As we have seen in the first part, we have no record of man's knowledge of the nervous system until writing was invented. Those who knew about the nervous system and recorded it were the Egyptians. But, as you can imagine, the knowledge of the...
John j. Wild, a World War II surgeon, became interested in using ultrasound as a noninvasive method to detect bowel injury. Using A-mode equipment, originally designed to read radar maps of enemy territory, he was able to accurately measure bowel wall thickness and to identify...
Capítulo VII: Galeno de Pérgamo y la teoría del pneuma. Pneuma es una palabra en griego antiguo que significa “respiración” o “espíritu”, palabra vinculada con el aire. Para Galeno había “espíritus” que viajaban por las arterias, las venas y los nervios para dar movimiento a nuestros músculos. Estos espíritus...
Because bone structures are preserved after death and the rest of the body is not, trepanations are the oldest evidence of surgery among Homo Sapiens. But what could have led to a Homo Sapiens to pierce the head of another fellow Homo Sapiens? And what...
It is impossible to know who the first human being was that saw a brain, and what they felt when they saw it. Trepanned skulls have been found in numerous cultures around the world, that is to say, the skulls were intentionally drilled by another human...
Por Fernando Martínez Benia y Luis Domitrovic (ladvic) Introduction What is neuroscience? This is a set of scientific and clinical disciplines that focus on the study and treatment of the nervous system and its disorders. They cover a broad spectrum and so it’s difficult to cover them all...
A medida que nos acercamos a nuestros tiempos (aunque aún nos falta mucho todavía), es inevitable mencionar a Claudio Galeno. Galeno nació en Pérgamo (actualmente Turquía), en el 129 DC y murió en Roma cerca del año 200. Fue una influencia ineludible para la mayoría de...
A-mode (amplitude-mode) US represents a one-dimensional characterization of a reflected sound wave that uses a pulse-echo technique to determine the depth and dimensions of an organ. Echo amplitude is plotted on the vertical axis, and the time needed for the echo to return is plotted on the...
The first physician to use ultrasound for medical imaging was Karl Dussik. Karl Dussik (1908-1968) an Austrian Neurologist Transducers were placed on both sides of a patient’s partly submerged head. The sound waves were transmitted at a known rate from one transducer to another transducer. The changes...
Luego de ver a Hipócrates, debemos enfocarnos en algunos personajes que escribieron textos médicos con sus observaciones y descubrimientos. De esta forma ayudaron a comprender mejor al sistema nervioso a quienes vivieron en aquella época. Por cuestiones lógicas de cómo se generaba el saber, la...
