Introduction

Synaptic Plasticity Mechanisms represents a key pathological mechanism in neurodegenerative diseases. This page explores the molecular and cellular processes involved, their contribution to disease progression, and therapeutic implications. [@synaptic2024]
Overview
Synaptic plasticity is the ability of synapses to strengthen or weaken over time in response to activity. This fundamental process underlies learning, memory, and adaptive neural circuitry. Both [long-term potentiation](/mechanisms/long-term-potentiation) (LTP) and long-term depression (LTD) forms of plasticity are crucial for cognitive function. Synaptic plasticity is mediated by complex molecular cascades involving neurotransmitter receptors, intracellular signaling pathways, and gene expression changes. [@molecular2023]
LTP (Long-Term Potentiation)
[Long-term potentiation](/mechanisms/long-term-potentiation) is a persistent strengthening of synapses based on recent patterns of activity. [LTP](/mechanisms/long-term-potentiation) is considered one of the major cellular mechanisms underlying learning and memory. [@synaptic2023]
Molecular Mechanisms
Early Phase (E-LTP)
The early phase of LTP lasts 1-3 hours and involves: [@tau2022]
Long-term depression is a persistent weakening of synaptic strength, equally important for learning and memory as it allows for synaptic pruning and refinement.
The study of Synaptic Plasticity Mechanisms has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
