Primera observación directa a las señales de baja frecuencia del cerebro
Un equipo de científicos de la Washington University School of Medicine han logrado realizar la primera observación directa a una de las bases más fundamentales del cerebro humano: una señal que nunca se apaga y que podría ser el puntal de numerosas funciones cognitivas.
La señal estudiada es de baja frecuencia y se genera por la actividad neuronal a través de todo el cerebro. Además, esta señal no se detiene ni siquiera cuando dormimos.
Para captar esta información, los científicos utilizaron la técnica de exploración de resonancia magnética funcional (fMRI) con la que realizaron detallados análisis de la actividad cerebral en varios individuos mientras éstos no llevaban a cabo actividad alguna.
El descubrimiento nos daría pistas sobre la arquitectura funcional de nuestro cerebro y las interacciones entre las diversas regiones de éste. Pese a que los datos son muy recientes, el equipo de investigadores confía obtener más información para poder comprender uno de los órganos más complejos que existen.
