This study investigated the role of lung vagal afferents in the respiratory related evoked potential (RREP) response to inspiratory occlusions using double lung transplant recipients as a lung denervation model. Evoked potential recordings in response to inspiratory occlusions were obtained from 10 double lung transplant recipients (DLT) with normal lung function and 12 healthy control subjects (NOR), under the attend, ignore and unoccluded conditions. Results demonstrated that early-latency RREP components, P1, P1a, Nf and N1 were not significantly different between the DLT and the NOR groups. Late-latency RREP component, P3, was identifiable in all DLT subjects during the attend trial. However, P3 latency was significantly longer in the DLT group as compared with the NOR group. The zero-to-peak amplitude of P3 was also significantly smaller in the DLT group than that in the NOR group during the attend trial. These results suggest that lung vagal afferents were not essential to elicit RREP responses, but may contribute to the cognitive processing of respiratory stimuli.
