Fig. 8. Habituated DCMDs (approach 15) were able to respond to objects approaching along a new trajectory (approach 16) with a significantly higher peak spike rate, spike rate 200 ms before collision and number of spikes. The new trajectory did not dishabituate the response to the original trajectory (approach 17). (See text for statistical parameters, significance assessed as in Fig. 6). `locust', black bars; `bird', open bars. Data are plotted as the mean ± S.D. (N=11).
