Few Genes Control Neuronal Function

Caption

The magenta-colored structures are nerve cells that use odorant receptor 47b, which senses pheromones. Expression of this receptor is controlled by the transcription factor E93. When E93 is removed, the neurons lose their ability to fulfill their task do detect pheromones, as evidenced by the deactivation of the fluorescent proteins (image to the right). The glowing, green cells, that use olfactory receptor 92a, are not affected because they are controlled by other transcription factors.
