Motor and exploratory profile of cockroaches, 7 days after head STZ injection. n = 8. 8-minute video recordings of (A) track plot and (B) heat map were analysed with the ANY-maze (Stoelting CO, USA) software. One-way ANOVA with Tukey’s multiple comparisons test indicated a significant decrease in (C) total distance travelled and (D) maximum speed, as well as a significant increase in (E) total time immobile and (F) total time in periphery in cockroaches exposed to 74 and 740 nmol STZ head injection, compared with cockroaches in the control group. All values are mean ± SD. * indicates a significant difference from control
