Brain preservationRated Jun 18, 2026Website ↗
Continuity
61.6/ 100

How much of the actual person could plausibly continue or be brought back.

Legacy
66.2/ 100

How richly others can remember, reconstruct, or study the person later.

What this preserves

Research company focused on brain preservation technologies.

Public dimension scores

We show only high-confidence dimensions here. Lower-confidence machine calls stay internal until the evidence is good enough. That keeps hallucinations minimized.

6 dimensions withheld by the public confidence gate.

Detail fidelity

9.0/ 10

The core evidence says synapses were visible by electron microscope in a preserved pig brain. That is unusually fine-grained preservation, even if the tissue is dead and function is gone.

Confidence: high

Intentionality

10.0/ 10

Human preservation is the point, not a side effect. Nectome explicitly frames the service as preserving neural information for possible later mind reconstruction.

Confidence: high

Facet coverage

Body

Covered

Physical body or tissue substrate preservation.

Fidelity8.0 / 10

Nectome is presented as preserving whole brain tissue and storing donated brain material, which is direct preservation of physical tissue substrate.

Brain / connectome

Covered

Brain structure, connectome, or neural substrate preservation.

Fidelity9.0 / 10

This is the core claim. The evidence says Nectome preserved an entire mammalian brain at nanoscale detail, with synapses visible by electron microscope, to retain neural information for possible later reconstruction.

Genome

Not shown

Genetic blueprint preservation.

Fidelity0.0 / 10

The evidence discusses preserved brain tissue, synapses, and neural information, but does not say Nectome offers genome preservation as a distinct product or goal.

Memories

Covered

Autobiographical memories and life stories.

Fidelity2.0 / 10

Nectome frames preserved brains as a possible backup for later mind reconstruction, which implies memory preservation as an intended downstream use. But the evidence also says memories have not been shown recoverable from dead preserved tissue.

Personality

Covered

Stable traits, conversational style, preferences, and temperament.

Fidelity2.0 / 10

The company says preserved neural information could support reconstructing the mind, which would include personality if that ever worked. The missing part is obvious: the evidence shows no demonstrated recovery of a mind from preserved tissue.

Social graph

Not shown

Relationships, affiliations, and interaction history.

Fidelity0.0 / 10

Nothing in the evidence shows Nectome preserving relationship data, affiliations, or interaction history as records separate from brain tissue.

Likeness

Not shown

Face, image, video, avatar, or visual representation.

Fidelity0.0 / 10

The evidence is about preserved brains and possible mind reconstruction, not face images, video, avatars, or visual representation.

Voice

Not shown

Voice recordings or voice model representation.

Fidelity0.0 / 10

No evidence shows Nectome collecting or preserving voice recordings or building voice models.

Values / beliefs

Not shown

Stated values, beliefs, commitments, and opinions.

Fidelity0.0 / 10

The evidence does not show Nectome separately preserving stated beliefs, commitments, or opinions. Broad talk about reconstructing a mind is not enough to claim this facet directly.

Genealogy

Not shown

Lineage, ancestry, family records, and inherited identity.

Fidelity0.0 / 10

There is no evidence of ancestry, family records, or lineage preservation.

Behavioral preferences

Not shown

Choices, habits, tastes, and behavior patterns.

Fidelity0.0 / 10

The evidence does not show Nectome directly preserving habits, tastes, or behavioral logs. Any such information would be speculative unless mind reconstruction were demonstrated, and it has not been.

Structured evidence

No structured public evidence has been extracted yet.
