OPTICAL STIMULUS PROBE WITH REFLECTING SURFACE

摘要

PURPOSE: A photo-stimulation probe equipped with a reflecting surface is provided to obtain good reaction signaling information by minimizing the distance between an electrode and a site which is stimulated through an optical signal. CONSTITUTION: A photo-stimulation probe(10) comprises a probe body(100), a photo irradiation body(110) attached to the probe body, and an electrode(120) accumulated in the probe body. The probe body is inserted inside body of a test subject like a rat. The electrode is arranged on the upper side of the front-end of the probe body. The electrode collects a reaction signal from a site which is photo-stimulated. An electrical conductive wire(130) is accumulated in the probe body. The electrical conductive wire is electrically connected with the electrode in order to transfer signaling information collected in the electrode to outside.
