🎯 Memory Formation Overview

This document showcases Memory Formation Systems as part of the Genome Logic Modeling Project (GLMP). These processes represent the sophisticated computational mechanisms by which neural systems encode, store, consolidate, and retrieve information over time.

Each process is modeled using the Programming Framework, demonstrating how memory formation operates as biological computation with precise algorithms for information processing, storage, and retrieval.

The processes are organized into four main categories: Memory Consolidation, Memory Retrieval, Memory Extinction, and Working Memory.

🎨 Programming Framework Color Coding

Triggers: Learning events, retrieval cues, consolidation signals
Enzymes: Transcription factors, kinases, memory-related proteins
Intermediates: Neural patterns, synaptic states, memory traces
Processing: Pattern completion, consolidation, retrieval algorithms
Products: Stable memories, behavioral responses, cognitive integration

💾 Memory Consolidation

Hippocampal-cortical transfer and stabilization

1. Hippocampal-Cortical Memory Transfer

The computational process by which newly encoded memories in the hippocampus are gradually transferred to cortical regions for long-term storage, involving replay mechanisms and synaptic consolidation.

Pattern completion and memory reconstruction

2. Pattern Completion Algorithms

The computational mechanism by which partial cues activate distributed memory networks to reconstruct complete memories through pattern completion and associative recall.

🗑️ Memory Extinction

Forgetting mechanisms and memory suppression

3. Active Forgetting Mechanisms

The computational processes by which memories are actively suppressed or forgotten through extinction learning, interference, and synaptic weakening mechanisms.
