The original version of this article unfortunately contained errors. The details are provided below:

1st correction: (see article title)

Instead of:

Electrophisiological

Say:

Electrophysiological

2nd correction: (see page 2 of the article)

Instead of:

$$ \mathrm{F}=\frac{{\left( signal/ noise\right)}_{\mathrm{at}\ \mathrm{the}\ \mathrm{input}}}{{\left( signal/ noise\right)}_{\mathrm{at}\ \mathrm{the}\ \mathrm{input}}} $$
(1)

Say:

$$ \mathrm{F}=\frac{{\left( signal/ noise\right)}_{\mathrm{at}\ \mathrm{the}\ \mathrm{input}}}{{\left( signal/ noise\right)}_{\mathrm{at}\ \mathrm{the}\ \mathrm{output}}} $$
(2)

3rd correction: (see page 4 of the article)

Instead of:

$$ \Delta \mathrm{f}=\frac{{\mathrm{f}}_{\mathrm{T}}}{{\mathrm{A}}_1}. $$
(14)

Say:

$$ \Delta {\mathrm{f}}_1=\frac{{\mathrm{f}}_{\mathrm{T}}}{{\mathrm{A}}_1}. $$
(14)

4th correction: (see page 4 of the article)

Instead of:

$$ {\mathrm{F}}_1=\left(1+\frac{{\mathrm{K}}_1}{{\mathrm{A}}_1\cdot {\mathrm{K}}_{\mathrm{e}}}\right)\sqrt{\frac{{\mathrm{A}}_1\cdot \varDelta \mathrm{f}}{{\mathrm{f}}_{\mathrm{T}}}}. $$
(15)

Say:

$$ {\mathrm{F}}_1=\left(1+\frac{{\mathrm{K}}_1}{{\mathrm{A}}_1\cdot {\mathrm{K}}_{\mathrm{e}}}\right)\sqrt{\frac{{\mathrm{f}}_{\mathrm{T}}}{{\mathrm{A}}_1\cdot \varDelta \mathrm{f}}}. $$
(15)

5th correction: (see page 4 of the article)

Instead of:

3- The gain bandwidth product (A1 .∆f) of the amplifier must be less than the cutoff frequency (fT) of the used operational amplifier.

Say:

3-The gain bandwidth noise product (A1 .∆f) must be higher than the cutoff frequency (fT) of the used operational amplifier.
