Episode description

En este episodio, actualizamos la neuroanatomía funcional del núcleo rojo a raíz del último trabajo pre-print de Krimmel (2024): The brainstem’s red nucleus was evolutionarily upgraded to support goal-directed action. Aprovechamos para traer de vuelta la crítica al tracto rubroespinal que hicimos en el #1 de Hemispherics y argumentamos el sentido evolutivo y funcional del núcleo rojo y sus conexiones en el ser humano adulto. ¿Es el núcleo rojo motor? ¿O tiene más función como nodo en una red más amplia de control ejecutivo de la acción? ¡Lo vemos en este episodio!
