Researchers have successfully visualized brain activity in a zebrafish. This discovery may aid in screening and discovering chemicals that affect neuronal activity in the brain.

A gSA2AzGFF49A;UAS:GCaMP7a double-transgenic larva was embedded in agarose, and a spot was presented on an LCD display placed on the right-eye side. Ca2+ signals were detected on the left tectum upon appearance (ON) and disappe
