Abstract
Desde la antigüedad clásica se ha intentado buscar una causa lógica al comportamiento de los pacientes psicóticos. En dicho anhelo por encontrar una explicación racional al comportamiento bizarro de ciertos pacientes, se ha recurrido a diferentes métodos: desde el estudio de los sueños y las curas de Asclepion (o asklepieion, del griego Ἀσκληπιεῖον) consagrado al dios Asclepio y su serpiente arquetípica, representación clásica del inconsciente, pasando por la demencia precoz de Kraepelin o el simbolismo del inconsciente colectivo de Jung. Por consiguiente, desde el nacimiento del método científico en la antigüedad clásica hasta la actualidad científica de nuestros días han existido y existen todavía hoy multitud de tentativas para dar una respuesta científica adecuada a dichos comportamientos inusuales. Asimismo, muchos estudios intentan analizar las relaciones interpersonales entre dichos pacientes denominados en la ciencia moderna con el término de “esquizofrénicos”. No cabe duda que el proceso de reconocimiento de caras de sus semejantes juega un rol principal en el establecimiento de dichas relaciones interpersonales, siendo válida esta afirmación tanto para sujetos sanos como para pacientes esquizofrénicos. El núcleo de esta tesis es el estudio de los cambios eléctricos cerebrales en pacientes esquizofrénicos, comparados con sujetos controles sanos, para intentar dilucidar si existen alteraciones en la actividad cerebral durante la presentación de estímulos de pares de caras humanas neutras. Se han elegido a propósito caras emocionalmente neutras para evitar precisamente cualquier interferencia secundaría al aspecto emocional de dichas caras humanas. Hemos intentado dar respuesta a la cuestión de si los pacientes esquizofrénicos reaccionan más tardíamente al estímulo de caras neutras en comparación con los sujetos sanos controles...
Since classic antiquity, a logical cause for the behavior of psychotic patients has attempted to be found. In this desire to find a rational explanation for the bizarre behavior of certain patients, different methods have been used: from the study of dreams and the cures of Asclepion (or Asklepieion, from the Greek Ἀσκληπιεῖον) consecrated to the god Asclepio and his archetypal snake, to the early dementia of Kraepelin or the symbolism of the collective sub-conscious of Jung. Thus, from the birth of the scientific method of classic antiquity to the current science of our times a multitude of attempts have existed and still exist in order to give an adequate scientific response to these unusual behaviors. At the same time, many studies try to analyze the interpersonal relationships between those patients classified by modern science with the term “schizophrenic”. There is no doubt that the process of recognition of the faces of their equals plays a principal role in the establishment of those interpersonal relationships, this statement being valid for healthy as well as for schizophrenic patients. The core of this dissertation is the study of the electrical changes in the brain in schizophrenic patients, as compared with healthy, control subjects, in order to try to clarify whether or not alterations exist in cerebral activity during the presentation of stimuli of pairs of neutral human faces. Emotionally neutral faces have purposely been chosen to specifically avoid any secondary interference whatsoever due to the emotional aspect of those human faces. We have attempted to answer the question of whether schizophrenic patients react later or not to the stimulus of neutral faces in comparison to the healthy, control subjects...
