Definition
A network of around 60 highly interconnected interneurons, the lobula plate tangential cells (LPTCs), is at the core of optic flow calculations in the fly visual system. Exquisite data is available for these cells on their anatomy and electrophysiology in vivo, including the characterization of responses to visual stimulation. Consequently, it has been possible to derive models that reproduce the morphology and the detailed electrophysiology of the cells within the network and to associate the features of the network to optic flow computations that it performs. The LPTC network therefore is a prime example of a neural circuit where sophisticated computations, connectivity schemes, and anatomy are understood in a unifying manner.
