[Generalized and local changes in the choline sensitivity of snail (Helix lucorum taurica Kryn) neurons after the single or tetanic local applications of acetylcholine].
Single or tetanic local applications of acetylcholine to the soma of command Helix lucorum identified neurons LPa3 and RPa3 induce general and local changes in somatic cholinosensitivity. The general decrease in cholinosensitivity depends on a distance of the tested membrane zones to the site of conditioning stimulation and its intensity. The qualitative and quantitative differences in general and local chemosensitivity have been revealed which can determine the selectivity in changes of chemoreceptor membrane reactivity.
