6.2.1 Detection mechanisms

Figure 6.12: The neural circuitry directly supports motion detection. As the image feature moves across the retina, nearby feature detection neurons (labeled $ a$ and $ b$) activate in succession. Their outputs connect to motion detection neurons (labeled $ c$). Due to different path lengths from $ a$ and $ b$ to $ c$, the activation signal arrives at different times. Thus, $ c$ activates when the feature was detected by $ a$ slightly before being detected by $ b$.
