La aplicación de corriente eléctrica a ciertas partes del cerebro puede mejorar las habilidades matemáticas de las personas hasta por seis meses, dice un estudio de la Universidad de Oxford.
Mediante unos electrodos, investigadores en neurociencia aplicaron pequeñas descargas a zonas particulares del cerebro que juegan un papel en la capacidad para calcular, mientras completaban una serie de problemas matemáticos.
En algunos estudiantes la corriente iba del lóbulo parietal derecho al izquierdo, en otros a la inversa y en un tercer grupo la corriente se apagaba después de 20 segundos.
Los cientÃficos detectaron que los estudiantes que recibÃan las descargas que fluÃan de derecha a izquierda obtuvieron buenos resultados en las sesiones matemáticas.
El descubrimiento podrÃa servir para asistir a aquellos que tienen problemas con números.
