I HAVE IT ON THE TIP OF MY TONGUE colloquial way of saying that you know the name or the word but that you have a temporary mental block that prevents the nerve pathways from reaching the neurons that store the information. It can be temporary forgetfulness, and at any time access occurs, but sometimes it is permanent and must be re-recorded in new neurons with new pathways to find it again in the future. The truth is that the person who says this phrase practically never gets to remember because in the effort he gets stressed and generates waves of frequencies that interfere with the process of thinking, when it is time to have the greatest possible calm.
