Rapid solution changes were performed by use of a recording chamber so shaped that it had a minimal dead space. A volume ten times larger than the dead space flowed past the node within about 20 ms. The half-time of the change in Na current (INa)amplitude associated with changes between solutions of different [Na]:s was 100-150 ms, whereas the half-time of the change in INa associated with changes between solutions of different [Ca]:s was 200-300 ms. The external [Ca] affects INa through its action on the Na permeability properties of the nodal membrane. The difference in rate of effect between changes in [Na] and [Ca] was also noticeable when simultaneous changes were performed. These findings are discussed with regard to the properties of the nodal gap.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1111\/j.1748-1716.1977.tb10389.x Authors: Tom Brismar Abstract: Single myelinated nerve fibres were isolated and the nodal currents were recorded with potential clamp technique.
