Using functional and morphological analysis, this study demonstrates that in CA3 pyramidal cell recurrent axon terminals, the release probability and the number of voltage-gated calcium channels ...

When the signal reaches the axon terminals, the electrical charge changes once more: instead of sodium ions, it is the positively charged calcium ions that enter the extra-permeable cell membrane.

They lengthened its axon and tweaked the distribution of ion pumps for sodium, potassium, and calcium to match the known parameters of real motor neurons. Przedborski is interested in the contribution ...
