It turned out that a population of glia resides in the hearts of zebrafish.

That’s also the spot that these glia first appear early in zebrafish development.

That picture of the zebrafish brain illustrates the simultaneous creation of new synaptic connections between some neurons, and receding connections between others.

Frankland’s research at the hospital has focused on the kind of forgetting that takes place in the hippocampus when new learning takes place—the corresponding gain and loss of neuronal connections that the zebrafish brain showed.

Zebrafish are particularly fitting models for neuroscience research.
