You inject a squid axon with a small volume of 0.1 M NaCl and 0.1 M KCl, both containing radioactive sodium and potassium ions.
0.1 M KCl, both containing radioactive sodium and potassium ions:
1. which of the ions do you first detect in the solution that bathes the neuron
at rest?
2. And after stimulating the neuron to generate several action potentials, which of the ions do you detect first in the solution bathing the resting neuron?
