摘要： A method is provided for in vivo detection of a biochemical substance in an animal by culturing neurofluocytes that stably express a receptor of the biochemical substances by transfecting cells with cDNA of the receptor and a tag that will emit a detectable energy in the presence of the biochemical substance, implanting the neurofluocyte into the animal's brain; and detecting the energy emission of the tag. In a first embodiment, the biochemical substance is a neurotransmitter, the tag is a fluophore, and the step of detecting includes forming an opening in the animal's skull and optically detecting fluorescent emissions using a two-photon laser scanning microscope. Multiple biochemical substances can be simultaneously detected by culturing neurofluocytes that express different receptors and have different fluophor tags that produce fluorescent signals at distinguishable wavelengths.
