A test for multiplication in insect directional motion detectors

Horridge, George Adrian; Marcelja, L.


The H1 neuron is a directionally sensitive motion-detector neuron with a large field that is fed by many high-resolution motion detectors in the fly optic lobe. As a stimulus pattern for it we used a random pattern of 50% bright and 50% dark squares on an oscilloscope screen. When this pattern is jumped by a small increment the HI neuron gives a directional response. When the jump is greater than one pixel on the screen the response falls and becomes non-directional because jump direction can...[Show more]
