\"\"<\/a>Nuestro\u00a0entendimiento del procesamiento de la informaci\u00f3n luminosa se basa en el estudio de conos y bastones y sus caminos post-receptoriales. Al comienzo de este siglo un nuevo tipo de fotorreceptor fue descubierto en la retina: las c\u00e9lulas ganglionares melanops\u00ednicas. Estas c\u00e9lulas proveen la informaci\u00f3n f\u00f3tica para las funciones no-formadoras de imagen, tales como el reflejo pupilar a la luz y a la sincronizaci\u00f3n del ciclo circadiano. Pero todav\u00eda su funci\u00f3n en otros centros neuronales responsables de la visi\u00f3n no ha sido dilucidada<\/span><\/p>\n

Mis intereses y objetivos se pueden resumir en producir conocimiento sobre c\u00f3mo es el procesamiento temprano de la funci\u00f3n visual, las implicancias del descubrimiento de las c\u00e9lulas melanops\u00ednicas en el procesamiento de la radiaci\u00f3n \u00f3ptica y el desarrollo de equipos y procedimientos para detectar enfermedades que afectan la visi\u00f3n.<\/span><\/p>\n
