Before revision:  However, there is ample evidence that neurons can have gating - i.e. multiplicative - interactions. Such gating interactions have significant effects on the collective dynamics of the network. Furthermore, the best performing RNNs in machine learning have gating interactions.
After revision:  However, there is ample evidence that neurons can have gating - i.e. multiplicative -- interactions, and gating is also a central feature of the best performing RNNs in machine learning have gating interactions.
