redletterdave points out work from Japanese researchers who produced an incredible visualization of how a brain perceives its environment. Studying zebrafish larvae, the scientists were able to observe neuronal signals in real time as the zebrafish saw and identified is prey, a paramecium.

The work is important because it demonstrates direct mapping of external stimuli to internal neuron activity in the optic tectum.
