After several students requested copies, I posted two movies on youtube, one of how visual input to balance can make a baby fall when visual stimulation is perverse.  The other shows how the owl’s vestibular system allows its neck to quickly counterrotate to compensate for the body’s movement. Both videos make people laugh.

Free neural network simulation engines, good for understanding simple cognitive-style networks, abstracting away from the actual reality with all those pesky ion channels and membrane potentials and spikes. Emergent is a workhorse, used by serious neural networks researchers but also useful for learning, in conjunction with an associated neural nets textbook, which is probably good for advanced undergraduates.
