Can you remember the smell of flowers in your grandmother’s garden or the tune your grandpa always used to whistle? Some childhood memories are seemingly ingrained into your brain.

This extracellular structure envelops certain neurons, thereby stabilizes existing connections – the synapses – between them and prevents new ones from forming. But what if we could remove the perineuronal net and restore the adaptability of a young brain? The neuroscientist Sandra Siegert and her research group at IST Austria now published two promising techniques to do so.
