#1: El tracto rubroespinal: ¿una vía vestigial? | Hemispherics

Primer episodio de Hemispherics, el podcast de Fisioterapia y Neurorrehabilitación, presentado por Javier Sánchez Aguilar. Este episodio trata sobre una síntesis de investigaciones sobre el tracto rubroespinal, enfocada bajo la pregunta de si esta vía es vestigial en humanos adultos, como afirman algunos estudios. Revisamos la neuroanatomía básica, algunos estudios sobre el núcleo rojo, la filogenia del tracto rubroespinal y la posible relevancia clínica de dicho tracto ante lesiones del sistema nervioso central.
