A Novel Form of Stereo Vision in the Praying Mantis

posted by Jenny on February 17, 2018

Our latest paper on mantis stereopsis has just come out in Current Biology. Briefly, we find that mantis stereopsis operates very differently from humans’: it is based on temporal change, and does not require the images to be correlated. We … Continue reading

Why don’t we see the world upside down?

posted by Jenny on January 20, 2017

This question comes up occasionally and I was just recently asked a similar question by email, so I thought it would be a good idea to do a blog post that everyone can see. Although there’s a great article on … Continue reading

Mantis videos

posted by Jenny on November 3, 2016

In our lab, we run experiments on praying mantis vision. We show the insects videos on a computer (mainly boring stimuli like bars moving, or little black dots which are meant to simulate a bug) and video how they move, … Continue reading
