Neurons in many species have large receptive fields that are selective for specific optic flow-fields. In a recent study the neural mechanisms underlying flow-field selectivity in the so-called H2-cell of the blowfly was investigated. For the first time it was shown that the direct contact between two cells from opposite brain hemispheres is sufficient to explain flow-field selectivity of a neuron utilized by the blowfly for appropriate steering maneuvers.
