Neuron-level brain-activity map: the Larval Zebrafish edition

Nature recently reported that for the first time, researchers have been able to image an entire vertebrate brain at the level of single cells. For this, they have used a larval Zebrafish that is genetically engineered to have their neurons fluoresce when nerve cells fire. By putting this fish under a special microscope, full brain activity can be recorded every 1.3 seconds. An hour of these recordings adds up to a Terabyte of data. Let’s take a look at some of this pretty data right here:
