Document Summary

And then after a while, turn away and see that everything seems to be going upwards. F: first you try and track the pendulum back and forth with your eyes, and get sense of speed. But then, you look at pendulum again and keep your eyes still. If you use eye-head system (track pendulum), you are using your eye movements to see the speed of pendulum. If you use image retina system (keep your eyes still), it will look like the pendulum is moving faster: image retina system: how could neurons signal motion, reichardt motion detectors. Neuron 1 sends excitatory to an intermediate neuron which sends inhibitory neurotransmitters to its neighbour. Neuron 3 sends inhibioty neurotransmitters to neuron 4. Neuron 6, neuron 4, and neuron 2 all send excitatory neurotransmitters to a motion sensitive cell. What happens when something is moving from right to left. When object is moving from left to right.
