Scientists mapped 1mm3 of a human brain
Analysis
The claim that scientists have mapped 1 mm³ of a human brain is partially supported by recent research efforts, but the context and scope of "mapping" vary significantly. Several sources describe studies involving detailed histological reconstruction or imaging at the scale of 1 mm³, often focusing on specific brain regions or features rather than a fully comprehensive map of all cellular and connectivity details within that volume. Most sources are not from highly trusted or peer-reviewed outlets, and they often refer to preliminary or partial reconstructions, or imaging resolutions at 1 mm³ scale rather than a complete, high-resolution connectome or cellular map. Therefore, while there is evidence that 1 mm³ volumes have been studied and partially mapped at various levels, the claim as a broad statement lacks the nuance that these are partial, specialized, or technical achievements rather than a fully detailed, comprehensive map of a cubic millimeter of human brain tissue.

Duplicate of Bron 1, same partial support.
Focuses on MRI-based connectivity mapping, not direct 1 mm³ brain mapping at cellular resolution.
Discusses MRI volumetry at 1 mm³ resolution, not detailed brain mapping.
Mentions revealing unseen brain structure details and software tools, implying partial mapping but not full.
Refers to neuroimaging with 1 mm³ voxel size, not direct brain tissue mapping.
Studies anxiety mapping with MRI, unrelated to detailed 1 mm³ brain mapping.
Discusses MRI templates and brain mapping in general, no evidence of 1 mm³ detailed mapping.
Comparative neuroimaging studies, no direct evidence of 1 mm³ mapping.
Studies cortical expansion patterns, no direct 1 mm³ mapping evidence.
