Fig. 6. Patterned electrical stimulation of metathoracic nerve 5 can elicit behavioural gregarization. (A-I) Histograms showing the distributions of P_sol values obtained after immobilised locusts were electrically stimulated for 4 h by electrodes attached to the indicated branches of metathoracic nerve 5 or the extensor tibiae muscle. (J) Ventral view of the thorax and proximal hind leg dissected to show the metathoracic ganglion, nerve 5 and its principal branches and the extensor tibiae muscle. Values in bold are median P_sol values obtained after electrical stimulation at each location. Nerve 5A runs between two muscles in the coxa, hence its apparent sudden termination. Significance (Dunnet's post-hoc tests of ANOVA) is indicated by asterisks: ^*, P<0.05; ^**, P<0.01; ^***, P<0.001. Scale bar, 2 mm.
