Fig 5. Activation and inactivation of feeding related motor neurons leads to decline in feeding.

Fig 5

A, Experimental setup: yeast intake of larvae at 18°C and 32°C (% of larval body stained with red yeast) was determined after 20min of TrpA1-activation and shiTS-inactivation. B, Fold change in yeast intake; in both cases no dyed food could be observed in experimental larvae. C, Inactivation by shiTS of glutamatergic neurons results in decline of cibarial dilator muscle (CDM) postsynaptic potentials (PSP), but not in the antennal nerve (AN) motor pattern. D, Activation of glutamatergic neurons via channelrhodopsin (UAS-ChR2(H134R) or inhibition via halorhodopsin (UAS-eNpHR) resulted in direct tonic excitation or complete inhibition of the AN motor pattern.
