Odorant Transduction and Combinatorial Encoding in the Early Olfactory System

We briefly describe below our work on modeling odorant transduction and combinatorial encoding of the olfactory sensory neurons.

The antenna and the antenna lobe of the early olfactory system of the fruit fly brain are, respectively, described by the publications below. Electrophysiology recordings are available at the Fruit Fly Brain Observatory.
