Direct Current-Induced Calcium Trafficking in Different Neuronal Preparations

Table 1

Neuronal preparations and statistical tests used to evaluate DC-induced calcium relocation.

Type of experiment	Statistical test	Probability
(i) Axon in vivo
Anodal versus cathodal	One-way ANOVA followed by Dunn’s test
Anode in versus control in	Mann–Whitney U Rank Sum test
Cathode in versus control in	Mann–Whitney U Rank Sum test
Cathode versus anode (combined segments)	Mann–Whitney U Sum Rank test
(ii) Axon in vitro
Inner and outer chambers versus “anode in”	Mann–Whitney U Sum Rank test
Inner and outer segments combined versus control	Mann–Whitney U Sum Rank test
(iii) Spinal cord in vitro	-test
(iv) Synaptosomes
^45Ca present during stim	ANOVA followed by Holm-Sidak
^45Ca added 6 hrs after stim	-test
^45Ca in the presence of cobalt	-test
^45Ca/neuroaminidase/stim versus no neuroaminidase/stim	-test
Na^+ versus no Na^+, no stim	ANOVA followed by Dunn’s test
Na^+ versus no Na^+, stim.	-test
Osmotic shock	-test
Different electrodes	Mann–Whitney U Sum Rank test
