NFIA

We now know that specific ensembles of astrocytes become transcriptionally activated during learning, just like neurons do.

They express specific genes like cFos and elevated NFIA when an animal learns something new.

And structurally, they are physically wrapping their tiny tendrils around the neuronal synapses, enveloping the engram.

And they aren't just hugging the synapses passively, right? They are actively manipulating the communication.
