Memories are stored as synaptic plasticity patterns rather than chemical or emotional signatures
the verdict
SUPPORTED
the evidence backs this
confidence 90/100
Extensive neuroscience research demonstrates that long-term memories are encoded and stored primarily through enduring modifications in synaptic strength and connectivity patterns, such as long-term potentiation and structural plasticity.
