This article advances the thesis that durable memory is best understood not as the passive retention of discrete informational objects, but as the sustained organization of distributed neural relations across time. On this account, an experience becomes memorable when encoding and consolidation modify coordinated ensembles of neurons, synapses, and interacting brain systems in ways that preserve functionally significant structure despite continuous molecular turnover and ongoing plasticity. The persistence of a memory therefore need not require the permanence of every molecule, synapse, or cellular state initially involved in its formation. Instead, it may depend on the capacity of neural systems to maintain, reactivate, and reorganize relational patterns with sufficient fidelity to support later reconstruction.
The term Neurotenacity is introduced as a theoretical label for this capacity to preserve biologically instantiated organization while permitting adaptive change. It denotes neither neuronal immutability nor a single molecular mechanism. Rather, it describes the multiscale persistence through which long-lived neurons, synaptic plasticity, recurrent circuit dynamics, systems consolidation, and network-level redundancy may jointly sustain continuity. The concept accordingly reframes the apparent tension between stability and plasticity: memory requires stability sufficient to conserve learned relations, yet also flexibility sufficient to incorporate new experience, update predictions, and reorganize representations across changing contexts.
Within this framework, forgetting is not treated as a unitary process or as the simple inverse of memory. In some cases, forgetting reflects degradation or loss of the neural organization required for retention. In others, the relevant representation may remain partially preserved while access is impaired by altered cues, interference, competition, or disrupted pathways of retrieval. Remembering is therefore conceived as a reconstructive operation performed by a dynamic system: retrieval reactivates and reassembles distributed information, and each act of retrieval may modify the architecture from which the memory is subsequently reconstructed.
The broader implication is that autobiographical continuity and personal identity emerge from the cumulative organization of experience rather than from a perfectly preserved neural archive. Identity is supported by overlapping memory systems, habits, affective dispositions, learned expectations, and self-relevant narratives whose relations remain sufficiently coherent across time. This proposal is intended as an integrative theoretical framework rather than a settled empirical account. Its central prediction is that the durability of memory should be explained increasingly at the level of resilient, reconfigurable neural organization—across cells, circuits, and systems—rather than by reference to any single fixed storage locus.
