A dense starburst plexus is critical for generating direction selectivity

摘要

Morrie and Feller show that dense SAC dendritic coverage is critical for generating DSGC tuning and asymmetric SAC-DSGC connectivity is independent of distal SAC morphology. Furthermore, they show that the directional preference of SAC varicosities is determined by the local orientation of the most distal neurite segments with glutamate receptors.
