sentence: Thus it seems plausible that in addition to any indirect impairment from other cholinergic neurons upstream from the LPTCs , the cholinergic pesticide imidacloprid might act directly on the LPTCs.Imidacloprid at 0.39 μ M doses did not significantly affect the stimulus-evoked responses in our case as seen previously in other visual neurons downstream to LPTCs in the locust ( Parkinson et al ., 2017 ; Parkinson and Gray , 2019 ) .
