+# The feedforward interneuron `n_ff_inh` of a `CorticalBlox` connects to all excitatory (pyramidal) cells of the WTA circuits within the `CorticalBlox` and receives input from excitatory neurons of other `CorticalBlox` that connect to the current `CorticalBlox`. This interneuron is largely responsible for controlling the spiking rhythm of the ensemble of WTAs.
