TLDR
It is suggested that the different actions of acetylcholine on the D and H cell is not simply to bring them to the chloride equilibrium potential, but that instead there are differences in the membranes of these types of cells and that in the H cellas, there is an increased permeability to chloride whilst in the D cell, there has been increased permeable to sodium ions.About:

Potassium activation in Helix aspersa neurones under voltage clamp
Robert W Meech,N B Standen +1 more
TL;DR: It is concluded that depolarization of Helix neurones activates two types of potassium channel, one channel is voltage dependent and highly selective for potassium and the other channel saturates at high external calcium concentrations and is inhibited by external magnesium ions.

The sensitivity of Helix aspersa neurones to injected calcium ions.
TL;DR: When calcium chloride was injected into Helix aspersa neurones there was a fall in membrane resistance and the membrane potential became hyperpolarized.
Journal ArticleDOI
A voltage-sensitive persistent calcium conductance in neuronal somata of Helix.
TL;DR: The sensitivity to small depolarizations and persistence during prolonged depolarization suggests two roles for the Ca system in the generation of slow pace‐maker oscillations, and the inhibition of spontaneous bursting by Ca‐blocking agents supports this model.
Journal ArticleDOI
Mapping of nerve cells in the suboesophageal ganglia of Helix aspersa.
TL;DR: The axons from some cells have been traced following intracellular injections of CoCl2 and precipitation of CoS, which supported the electrophysiological method of tracing axons by recording antidromic spikes in the cell body following stimulation of a peripheral nerve.

Effects of serotonin on the generation of the motor program for swimming by the medicinal leech
TL;DR: Observations suggest that serotonin is a modulator of neuronal control of swimming by the medicinal leech, and this paper presents a study of the effects of serotonin on the neuronal generation of the motor program for swimming byThe leech.

TL;DR: In the present experiment, the e.p. c.c. equilibrium potential was measured in solutions of various ionic composition and the ions which contributed to the e-p.c., and the membrane potential at which it becomes zero may be called provisionally 'e.

TL;DR: The experiments reported in this paper were designed to establish toward which of these two species of ions the permeability is increased, potassium or chloride, both of which will probably be in a condition of equilibrium across the resting membrane.
