Reponses anomales a des courants sous-liminaires de certaines membranes somatiques (neurones géants d'Helix pomatia)
The subthreshold electrical behaviour of the giant neurones in the suboesophageal ganglion of the snailHelix pomatia was examined.

Neurones à ondes-salves des mollusques
i-V characteristics of bursting neurones are obtained directly, using a slow triangular function as the command to the voltage clamp system. With depolarizing ramp, thei-V characteristic isN-shaped; a region of ...

Evolution de la forme des potentiels d'action par stimulations répétitives
The shape of spikes elicited at a constant rate was compared with the changes of transmembrane currents obtained by repetitive activation of the somatic membrane (voltage clamp method).

Ondes paroxysmales induites par le métrazol (PTZ) sur les neurones d'Helix p.: Modèle fonctionnel
The convulsant pentylenetetrazol (PTZ), 1% induces paroxysmal depolarization shifts (PDS) on regularly firing neurones ofHelix. Synaptic or antidromic stimulation or transmembrane current produces PDSs followed b...

Anion channels in a human pancreatic cancer cell line (Capan-1) of ductal origin
Transepithelial solute transport and bicarbonate secretion are major functions of pancreatic duct cells, and both functions are thought to involve the presence of chloride channels in the apical membrane of th...
