A mind-brain problem might be explainable by the concept "Kasane-egaki (Oomori, 1994)". Kasane-egaki of the mind and brain is crucial and meaningful in medical treatment. For Kasane-egaki, it is important to note that the mind (psychiatric symptoms) must be translated into an expression which could be connected with the brain function, and vice versa. As a case of Kasane-egaki, a patient with left frontal infarction showing mild obsessive-compulsive-like symptoms is introduced.
 However, there are two situations in which Kasane-egaki of the mind and brain cannot be applied: visual agnosia and auditory hallucination of schizophrenia. The author discusses visual experiences of patients with associative visual agnosia, and the relation between auditory hallucination of schizophrenia and activation of the temporal lobe from the viewpoint of language function.
