MinnisBfrumur

MinnisBfrumur is a coined term used in speculative discussions of memory neuroscience and in some Icelandic-language fiction to denote a hypothesized class of neurons dedicated to encoding and storing memory traces. The name combines minnis (memory) and frumur (cells), with a capital B used in some texts to mark a proposed subtype or branding element.

In theoretical accounts, MinnisBfrumur would operate as memory-encoding units that integrate inputs from sensory cortices and the hippocampus, contribute to pattern completion during retrieval, and participate in the stabilization of long-term memories through activity-dependent plasticity. They are imagined to interact with synaptic and glial processes, aligning neural assemblies during consolidation periods after learning.

Anatomically, MinnisBfrumur are not defined in mainstream neuroanatomy. In speculative models they may be located within hippocampal subfields such as CA1 and CA3 and in certain cortical association areas, or represent a distributed network of neurons sharing common molecular markers and firing patterns. Proposed distinguishing features include distinctive receptor profiles, gene expression patterns, or synchronization with theta and sharp-wave ripple activity, although there is no empirical consensus.

Development and plasticity are described in hypothetical terms as experience-driven differentiation, maturation, and selective synaptic strengthening that would bias networks toward durable storage. Evidence is currently limited to theoretical discussions and fictional narratives; no peer-reviewed studies have validated MinnisBfrumur as a separate neural class.

In usage, the term serves as a conceptual tool for thinking about memory storage rather than a recognized biological category.
