The head of the spine is connected to the dendritic shaft by a 50-400 nm thin membrane tube, called the spine neck, which has been hypothesized to confine biochemical and electric signals within the spine compartment.

The extent to which compartmentalization is governed by spine morphology, particularly spine neck diameter, remains unresolved.
The dendritic spine neck has been hypothesized to confine biochemical and electrical signals within the spine compartment, potentially minimizing interspinal crosstalk and supporting spine-specific synapse plasticity.
Multidisciplinary approaches should help answer how dendritic spine architecture affects cellular and molecular processes required for synapse maintenance and modulation.
The review focuses on recent experimental and theoretical tool development for studying the role of the dendritic spine neck in compartmentalization.
