Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Biophysics

Context:

  • Neural memory mechanisms remain incompletely understood.
  • Synaptic plasticity is crucial for memory formation and retrieval.
  • Computational models are vital for exploring complex neural processes.

Purpose:

  • To simulate the recording and retrieval functions of neural memory.
  • To model memory engram formation and retrieval based on conformational processes.
  • To investigate factors influencing memory accuracy, reliability, and capacity.

Summary:

  • Neural memory functions are simulated via local conformational processes in synaptic fields, influenced by afferent patterns and synaptic microstructure.
  • Address domains, representing conformational loci, form multilayer coverings of neuronal address space, with superposition affecting memory dissemination and accuracy.
