I. Tasaki, MECHANICAL AND THERMAL-CHANGES IN THE TORPEDO ELECTRIC ORGAN ASSOCIATED WITH ITS POSTSYNAPTIC POTENTIALS, Biochemical and biophysical research communications, 215(2), 1995, pp. 654-658
Rapid mechanical and thermal changes in slices of the Torpedo electric
organ evoked by electric stimulation were investigated. The organ was
found to swell simultaneously with the postsynaptic potential. This s
welling was followed by prolonged shrinkage of the organ. These findin
gs may be explained from the proven facts that the acetylcholine(ACh)-
receptor proteins have a large binding capacity for Ca-ions and that a
ddition of ACh to the medium can cause release of Ca-ions from the rec
eptor proteins. (C) 1995 Academic Press, Inc.
