IONIC CURRENTS
The effect of the neuropeptide FMRFamide on Aplysia californica siphon motoneurons involves multiple ionic currents that vary seasonally
... the ionic currents contributing to the FMRFamide response was conducted on isolated abdominal ganglia, and we were therefore unable to characterize the siphon movements produced by individual LFS ...
