Fig. 1.

Calcium imaging of larval zebrafish. (A) A single axial plane from live two-photon imaging of a larval zebrafish brain is shown at 7 days post fertilisation on the left. On the right, sagittal and coronal views of a reference image [http://www.zbbrowser.com] [90] are shown to illustrate the 3D location of different brain areas. A zebrafish larva (not to scale) is shown at the bottom of the panel. (B) Example time series data are shown for regional averages of gross anatomical brain regions, as well as example cells identified in each area.
