Infantile amnesia is the name for the near-universal pattern where early life experiences don’t become lasting episodic memories.

Humans can often learn skills and emotional associations early on, but struggle to recall specific events later.

Scientists have long debated whether the brain fails to form those memories properly, erases them, or stores them in ways that make them difficult to access.

Microglia are a natural candidate to investigate because they are not just “defense” cells. In the developing brain, microglia help sculpt neural circuits by pruning synapses and influencing how networks mature.
