How a Frog Can Learn What Is WHere in the Dark

An insect floundering on water produces waves. Frogs have what are
called "lateral-line" organs on their skin, which can sense local
water velocity; similar organs exist in crocodiles and fish.
Amazingly, using this information, the frogs can
distinguish wave sources of different frequencies, presented
simultaneous, at different positions on the water surface.
The authors construct a realistic, trainable neural network that can
do precisely this. I for one, welcome our new Xenopic masters.
