How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to connectome is connectivity.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Neuroscience

The comprehensive wiring map of a nervous system

The term connectome was coined independently in 2005 by Olaf Sporns and colleagues, in a paper titled The human connectome, and by Patric Hagmann in his doctoral thesis From diffusion MRI to brain connectomics. A connectome is a comprehensive map of the connections in a nervous system: the full set of neural elements, whether individual neurons or larger brain regions, together with the links that join them, described as a network of nodes and edges. The idea is modeled on the genome as a complete catalogue, so that a connectome aims to inventory the wiring of a brain at a chosen scale rather than to trace any single pathway. What makes it a landmark is its scope: it recast the study of brain connectivity as the mapping of an entire connection network, and it gave rise to large coordinated efforts such as the Human Connectome Project led by David Van Essen and colleagues, which set out to chart human brain connectivity across many individuals.[1][2][3]

Unit
A whole-network map of neural connections at a chosen scale, from the synapse level to the brain-region level
Recovery means
Not applicable
Measured by
Reconstructed from connectivity data and represented as a graph of nodes and edges: electron-microscopy tracing at the cellular scale, or diffusion MRI tractography and functional imaging at the whole-brain scale
