Stages
- 1.Genetic targeting of neural cell populations(library_design)
The review states that cell-type-specific genetic tools allow interrogation of neural circuits with increased precision.
Selection: cell-type-specific access using recombination-based or activity-driven genetic targeting approaches
- 2.Anatomical tracing of neural circuits(functional_characterization)
The abstract states that functionally precise brain mapping requires anatomically tracing neural circuits.
Selection: use contemporary viral tracing strategies to define circuit architecture
- 3.Monitoring neural activity patterns(functional_characterization)
The abstract states that functionally precise mapping requires monitoring activity patterns and lists multiple monitoring modalities.
Selection: use electrophysiological recording methods, calcium indicators, voltage indicators, and neurotransmitter or neuropeptide biosensors to observe circuit function
- 4.Manipulation of neural activity to infer function(confirmatory_validation)
The abstract states that manipulating neural activity is required to infer function.
Selection: use genetically targeted cellular ablation, optogenetics, chemogenetics, or ion-channel over-expression for acute or chronic perturbation

Operational role: sensor. Implementation mode: genetically encoded. Cofactor status: cofactor requirement unknown.
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.

Ranked Claims
Functionally precise mapping of the mammalian brain requires tracing neural circuits, monitoring their activity patterns, and manipulating their activity to infer function.
Calcium indicators, voltage indicators, and neurotransmitter or neuropeptide biosensors are being used to investigate circuit architecture and function.
Genetically targeted cellular ablation, optogenetics, chemogenetics, and over-expression of ion channels are methods for acute or chronic manipulation of neural activity.
