We have also found that the form of visualization common in normal speech is the visualization of eye sensations; that in unusual situations we may have visualizations from other sense areas, such as the ear, taste or smell, but these are the RARE EXCEPTION. From all this data it would naturally follow that some sort of term is needed to designate this condition. Last year I probed to find such a term without much success. At present I see no reason why it should not be called an Asthenia; it is surely the weakening of a mental process that is strong in normal individuals. The evidence here presented shows that. I doubt whether there is any marked pathological change, since the individual may be educated out of it; but this does not necessarily follow as proven with my dog in Berlin.[2] As a general designation, then, I should consider Asthenia as apropos. One objection to this is that the weakness is by this terminology lacking in localization. Our data above has shown us that the location of the trouble is visual; that is, it is situated about a centre of sensory registration that deposits data from the eye; this must naturally then be located somewhere in or near the cuneus. We could therefore add to the terminology this idea of a minute localization and call it a Centre Asthenia. Some may prefer to carry the matter one step farther and add the name of the centre in which this weakness is located, but I fear if I take this step and complete my terminology by the word "Visual Centre Asthenia," it will, as such, not cover quite all the cases, for I find that sometimes the visualization is absent in other areas as well, and also the holding of an emotion of pleasure or pain and of other dominating mental attitudes that are sometimes visualized would not, therefore, be included. I would therefore retract the broader claim in order to place the term on a conservative basis and call the essence of the lesion simply no more or less than a Centre Asthenia. As well as visual Asthenia, the following terms might be considered as applicable: collaborative centre asthenia; imaginative centre asthenia; visual creative centre asthenia; picture producing centre asthenia. We say neurasthenia when the trouble is not in the nerves as such, so much as it is in the collaborative centres. More of this later. Here in stuttering the trouble is also collaborative, and we can be still more definite than that and say the trouble is with the collaboration of visualization. So if I were forced, however, to choose one term from all these, my choice would be "Visual Centre Asthenia." This indicates a new and rational treatment. But of this later.
