If different organizations of nervous tissue can achieve the same functions, the possibility that cognitive capacities, including sentience, can be achieved by other tissues should be considered.

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Cognitive capacities including sentience can be achieved by non-neural tissueshypothesis0.904
  Central hypothesis: sentience is not exclusive to neural systems; other biological substrates may achieve felt states.
• Cognitive functions, including sentience, can potentially be achieved by very different systems and their disparate substrates.claim0.883
  Central multiple-realizability claim of the paper, from abstract and §2.
• There is no privileged material substrate for Selves; cognition can arise in neurons, single cells, plants, tissues, swarms, and engineered systems.claim0.833
  Second foundational pillar of TAME; supports basal cognition and rejects brain-centrism.
• Cognitive capacities exist on a spectrum and tools from behavioral sciences can be productively applied to understand and control systems far beyond familiar animals with central nervous systems.claim0.808
  Core tenet of diverse intelligence; justifies the methodological borrowing across fields.
• Cognitive capacities evolve through continuity across natural, hybrid, and synthetic life forms using conserved bioelectric mechanismsclaim0.804
• Cognitive functions such as sentience are always inferred.claim0.802
  First sentence of the paper, establishing the inferential nature of all sentience attributions.
• Intelligence and cognition exist on a continuum; modern bioscience offers no support for clean bright-line distinctions between cognitive and non-cognitive beings.claim0.800
  Anti-essentialism claim: questions like 'is it cognitive?' are scientifically unjustified; modern view must ask 'what kind' and 'how much'.
• Non-neural morphogenetic agents satisfy most sentience criteria via electrically active cells rather than neuronsfinding0.797
  Empirical basis for expanding sentience frameworks; shows Crump criteria adaptable beyond traditional neurocentric definitions.
