The H1 neuron measures change in velocity irrespective of contrast frequency, mean velocity or velocity modulation frequency

Jian, Shi; Horridge, George Adrian


The H1 neuron of the fly Lucilia cuprina is one of the wide-field motion-perception interneurons of the lobula plate. The response, measured as the mean spike rate over many repetitions of the same stimulus sequence, is initially large at the onset of a movement, quickly falling to a plateau and then continuing to adapt slowly when the stimulus is a steady motion of a pattern. Modulation of the velocity of the moving pattern (velocity contrast) causes a modulation of the mean spike rate, which...[Show more]
