Escape Sequence in Response to Front Looming Stimulus Showing Prejump Changes in Leg and Body PostureA key feature of reactive behaviors is the ability to spatially localize a salient stimulus and act accordingly. Such sensory-motor transformations must be particularly fast and well tuned in escape behaviors, in which both the speed and accuracy of the evasive response determine whether an animal successfully avoids predation [1]. We studied the escape behavior of the fruit fly, Drosophila, and found that flies can use visual information to plan a jump directly away from a looming threat. This is surprising, given the architecture of the pathway thought to mediate escape [2, 3]. Using high-speed videography, we found that approximately 200 ms before takeoff, flies begin a series of postural adjustments that determine the direction of their escape. These movements position their center of mass so that leg extension will push them away from the expanding visual stimulus. These preflight movements are not the result of a simple feed-forward motor program because their magnitude and direction depend on the flies' initial postural state. Furthermore, flies plan a takeoff direction even in instances when they choose not to jump. This sophisticated motor program is evidence for a form of rapid, visually mediated motor planning in a genetically accessible model organism.Card and Dickinson, Visually Mediated Motor Planning in the Escape Response of Drosophila, Current Biology (2008), doi:10.1016/j.cub.2008.07.094

Not an insect. Not venomous. Can't quite run that fast. Can't quite get that large. I wish I had a job where I could just make up bullshit like this and get paid for it.

Funky Python needs your help reaching the delicious fruits and tasty bugs that make up his diet. When he eats three of the same colored fruits or insects in a row, his tail grows, making it more challenging to move him across your screen but also inching you closer to the end of the level. You'll have to complete Funky's tail before time runs out,

When I think of the brain body connection, I usually don’t think about flies. Those annoying household pests aren’t high on my list for either intelligence or brawn. But I have to admit they are speedy little insects; much faster than me when I try to swat one.
