Title
An analog VLSI model of the fly elementary motion detector
Abstract
Flies are capable of rapidly detecting and integrating visual motion in- formation in behaviorly-relevant ways. The first stage of visual mot ion processing in flies is a retinotopic array of functional units known as el - ementary motion detectors (EMDs). Several decades ago, Reichardt and colleagues developed a correlation-based model of motion detection that described the behavior of these neural circuits. We have implemented a variant of this model in a 2.0- analog CMOS VLSI process. The re- sult is a low-power, continuous-time analog circuit with integrated pho- toreceptors that responds to motion in real time. The responses of the circuit to drifting sinusoidal gratings qualitatively resemble the t emporal frequency response, spatial frequency response, and direction selectivity of motion-sensitive neurons observed in insects. In addition to its pos- sible engineering applications, the circuit could potentially be used as a building block for constructing hardware models of higher-level ins ect motion integration.
