differential amplifier

an electrical device that amplifies the voltage difference between two input leads. In neural research, potential changes may be as small as 1 μV, and electrical resistances and sources of interference may be greater than the voltages being studied. Thus, complex electronic equipment, such as a differential amplifier, is required.

linear correlation

linear correlation

a measure of the degree of association between two variables that are assumed to have a linear relationship, that is, to be related in such a manner that their values form a straight line when plotted on a graph. It provides an index of the degree of constant change in the value of one variable (y) for each unit change in the value of another variable (x).
