Time for some off-topic science bits!
In the last two weeks I was busy participating in a project about visual neurobiology and I had so much fun that it’s worth a short post.
What did we do?
We took 10 adult male wandering spiders (Cupiennius salei), put them into an “arena” one by one (by “tickling” them with a cotton ball – no, really) and let them choose one of two “targets” (black cardboard figures at the back of the arena). Repeat about 300 times using different targets.
Why did we do it?
To learn more about their vision: what shapes they can distinguish from each other and/or find more attractive – without harming them. Makes interpretation that much harder though.
What are the results?
The larger the black area, the better. Shapes closer to the ground are also more favourable. Sloping edges not so much.
Oh dear, I love biology.
