The paper identifies compartment-specific mitochondrial Ca2+ dynamics in neurons and their molecular regulators, showing how these differences affect neuronal development.

This study shows that protein synthesis inhibition reduces engram synapse density and spine size, impairing fear memory recall and optogenetic reactivation in mice.

This study tracks synaptic changes in the hippocampus during fear memory formation and extinction, showing synaptogenesis and synapse modification between CA3 and CA1 engram cells.

The paper shows that associative fear memory increases spine size at synapses between engram cells in the amygdala, which decreases with extinction and recovers with re-conditioning.
