绿头苍蝇视觉系统中的神经元具有对特定光流场具有选择性的大感受野。在这里，我们研究了神经机制的流场选择性在近端垂直系统（VS）的细胞，一个特定的子集的切向细胞的苍蝇。这些细胞具有局部优选方向，其分布为例如匹配在苍蝇旋转期间发生的流场。然而，导致这种选择性的神经回路尚未完全理解。通过近端VS细胞和其他切向细胞的双细胞内记录，我们的特点是特定的布线VS细胞本身之间和近端VS细胞和水平敏感的切向细胞之间。我们发现了一个尖峰神经元（Vi）参与了这个电路，以前没有描述过。这个神经元原来是连接到近端VS细胞通过间隙连接，此外，它被发现是抑制VS1。
Neurons in the visual system of the blowfly have large receptive fields that are selective for specific optic flow fields. Here, we studied the neural mechanisms underlying flow–field selectivity in proximal Vertical System (VS)-cells, a particular subset of tangential cells in the fly. These cells have local preferred directions that are distributed such as to match the flow field occurring during a rotation of the fly. However, the neural circuitry leading to this selectivity is not fully understood. Through dual intracellular recordings from proximal VS cells and other tangential cells, we characterized the specific wiring between VS cells themselves and between proximal VS cells and horizontal sensitive tangential cells. We discovered a spiking neuron (Vi) involved in this circuitry that has not been described before. This neuron turned out to be connected to proximal VS cells via gap junctions and, in addition, it was found to be inhibitory onto VS1.
