Essentially, the change that underlies neuroplasticity at the level of cells, which we call neurons or nerve cells, generally involves three different mechanisms. One is the strengthening of certain connections, what we call synaptic connections. Synapses are the location between neurons where they communicate with one another; it's actually a gap between the neurons, it is technically called the synaptic cleft. It's a gap, and within that gap, chemicals are passed across that gap that allow one neuron to activate other neurons or many neurons to activate many other neurons or to inhibit the activity of other neurons.

Here's a circuit 25:52 called lateral inhibition - an excitatory 25:55 neuron connects, or excites, an inhibitory 26:00 neuron, and that inhibitory neuron in 26:02 turn it feeds back to inhibit adjacent 26:05 neurons to the first one that was active.

Why do you want 30:31 to inhibit the 30:32 flexor motor neuron?

It also 31:04 connects to the inhibitory interneuron 31:05 which would, in this case, would inhibit 31:09 the flexor motor neuron.
