Association of Calcium with Membranes of Squid Giant Axon
نویسندگان
چکیده
Giant axons from the squid, Loligo pealei, were fixed in glutaraldehyde and postfixed in osmium tetroxide. Calcium chloride (5 mM/liter) was added to all aqueous solutions used for tissue processing. Electron-opaque deposits were found along the axonal plasma membranes, within mitochondria, and along the basal plasma membranes of Schwann cells. X-ray microprobe analysis (EMMA-4) yielded signals for calcium and phosphorus when deposits were probed, whereas these elements were not detected in the axoplasm.

Spatial localization of calcium channels in giant fiber lobe neurons of the squid (Loligo opalescens).
Whole-cell voltage clamp was used to investigate the properties and spatial distribution of fast-deactivating (FD) Ca channels in squid giant fiber lobe (GFL) neurons. Squid FD Ca channels are reversibly blocked by the spider toxin omega-Agatoxin IVA with an IC50 of 240-420 nM with no effect on the kinetics of Ca channel gating. Channels with very similar properties are expressed in both somati...
متن کاملCurrent-Voltage Relations in the Lobster Giant Axon Membrane Under Voltage Clamp Conditions
The sucrose-gap method introduced by Stämpfli provides a means for the application of a voltage clamp to the lobster giant axon, which responds to a variety of different experimental procedures in ways quite similar to those reported for the squid axon and frog node. This is particularly true for the behavior of the peak initial current. However, the steady state current shows some differences....
متن کاملIonic conductances of squid giant fiber lobe neurons
The cell bodies of the neurons in the giant fiber lobe (GFL) of the squid stellate ganglion give rise to axons that fuse and thereby form the third-order giant axon, whose initial portion functions as the postsynaptic element of the squid giant synapse. We have developed a preparation of dissociated, cultured cells from this lobe and have studied the voltage-dependent conductances using patch-c...
متن کاملSynaptic transmission in squid giant synapse after potassium conductance blockage with external 3- and 4-aminopyridine.
The release of transmitter substance from the presynaptic terminal of the squid giant synapse, in the absence of action potentials, has been among the most useful experimental paradigms in the study of chemical synaptic transmission (Bloedel et al., 1966; Katz and Miledi, 1967; Kusano et al., 1967). Early experiments using this technique demonstrated that neither sodium nor potassium currents w...
متن کاملCalcium-containing Electron-dense Structures in the Axons of the Squid Giant Synapse
Following the Oschman and Wall technique, electron-dense structures (EDS) were found on unstained, unosmicated membranes of squid giant synapse axons. These densities contain high concentrations of calcium and phosphorus as identified by energy dispersive X-ray analysis. Based on the signal strength, the quantity is significantly greater than that of other regions of the membrane or tissue spac...
