Abstract

Modulatory projection neurons gate neuronal networks, such as those comprising motor central pattern generators; in turn, they receive feedback from the networks they gate. A recent study has shown that, in the crab stomatogastric ganglion, this feedback is also subject to modulation: the enhanced feedback feeds forward through the projection neurons to modify circuit output.

摘要

调制投射神经元调节神经元网络，如运动中枢模式发生器组成的网络；反过来，它们又从其调节的网络接收反馈。最近的一项研究表明，在蟹的口胃神经节中，这种反馈也受到调制：增强的反馈通过投射神经元前馈，以修改电路输出。
