Bioadhesive steroid nanoparticles are used to prepare a rapidly disintegrating solid oral dosage form of steroid. The interface module has a single chip design and is coupled to the BIOS of a motherboard through a cable connection. The compounds of this invention are modulators of metabotropic glutamate receptors, particularly, mGluR2 receptor. Further, a response time of a response to the application is modulated for communicating with the application.
