When compensation becomes visible

How can a biological system look stable while an adaptation is building underneath?

One well-studied opioid mechanism gives us a concrete example. Repeated mu-opioid receptor activation can suppress part of the cell's cAMP signaling, while the cell gradually builds an opposing response. While both are present, they can partially balance one another. Removing the opioid signal can expose the adaptation that had been building underneath.

Established opioid mechanism

The signal arrives

Mu-opioid receptor activation can reduce activity in a cellular signaling pathway involving cAMP.

Established: repeated opioid signaling can recruit compensatory changes in the cAMP pathway.

Still open: how much this mechanism contributes to sustained kratom–kava withdrawal, and what additional adaptations kava may introduce.
