CNS memory structure
The concepts you raise in your question are not founded in neurobiology. We do not know what the biological correlates of a "unit of memory" are in the central nervous system.

Although oscillations are widespread in the brain, the relationship between oscillations and memory storage and recall is a subject of active research. The way you state this process in your question is not justified by any experimental evidence that I am aware of.

Memories do not have a "root neuron" — as I wrote above, we do not know how memories relate to neurons. Inhibitory neurons simply provide inhibitory input currents to their post-synaptic targets. Any relationship with "resonance" or oscillations relies on explicit assumptions about emergent network properties, and these are currently unfounded.
