Efectos en la amplitud y la latencia del componente N170 ante la presentación de rostros emocionales de ira y miedo
La discriminación de las emociones expresadas a nivel facial es importante para las relaciones sociales, la empatía y la interacción social. El objetivo de este estudio fue observar si existían diferencias en el procesamiento cortical ante dos emociones básicas, la ira y el miedo y definir si la percepción de la ira intensa genera una mayor modulación del componente N170 en amplitud y latencia en comparación con las imágenes de rostros con expresión de miedo intenso. Para este estudio se utilizó la técnica de potenciales evocados con un montaje de 32 canales. Se encontraron diferencias significativas en latencia para las imágenes de rostros que expresan ira intensa, comparados con la condición de imágenes de rostros de miedo intenso. Se enc... Ver más

| description |
La discriminación de las emociones expresadas a nivel facial es importante para las relaciones sociales, la empatía y la interacción social. El objetivo de este estudio fue observar si existían diferencias en el procesamiento cortical ante dos emociones básicas, la ira y el miedo y definir si la percepción de la ira intensa genera una mayor modulación del componente N170 en amplitud y latencia en comparación con las imágenes de rostros con expresión de miedo intenso. Para este estudio se utilizó la técnica de potenciales evocados con un montaje de 32 canales. Se encontraron diferencias significativas en latencia para las imágenes de rostros que expresan ira intensa, comparados con la condición de imágenes de rostros de miedo intenso. Se encontraron diferencias tanto de la amplitud como de latencia ante imágenes de rostros de ira y miedo intensos en comparación con imágenes de rostros neutros.

El objetivo de este estudio fue observar si existían diferencias en el procesamiento cortical ante dos emociones básicas, la ira y el miedo y definir si la percepción de la ira intensa genera una mayor modulación del componente N170 en amplitud y latencia en comparación con las imágenes de rostros con expresión de miedo intenso. Para este estudio se utilizó la técnica de potenciales evocados con un montaje de 32 canales. Se encontraron diferencias significativas en latencia para las imágenes de rostros que expresan ira intensa, comparados con la condición de imágenes de rostros de miedo intenso. Se encontraron diferencias tanto de la amplitud como de latencia ante imágenes de rostros de ira y miedo intensos en comparación con imágenes de rostros neutros.
