Abstract
There is provided a central nervous system labelling composition for intranasal administration for the purpose of labelling the central nervous system from the olfactory epithelium by way of the olfactory bulb and by means of intranasal administration. Additionally, there is provided a method of non-invasively labelling the central nervous system by way of an administration route that entails little transferability to the entire body. Furthermore, there is provided a screening method using a central nervous system labelling composition for intranasal administration. A central nervous system labelling composition for intranasal administration is characterized by labelling the central nervous system from the olfactory epithelium by way of the olfactory bulb and by means of intranasal administration and by containing at least one compound expressed either by the general formula (1) or the general formula (2) shown below as effective component:
