Five Methods for Neural Recording Application and Comparison of Neural Amplifiers

The so-called neural activity refers to the enhancement of electrical activity, metabolic activity and chemical secretion when the neural pathway performs normal functions. And neural recording is to speculate on the function of different brain regions by observing the neural activity when animals are stimulated or engaged in various activities. In order to improve the efficiency of neural recording, in this paper, a Complementary Metal Oxide Semiconductor (CMOS) amplifier for neural recording applications are investigated. More than this, three neural recording microsystems and a neural recording tag in a CMOS, which are helpful to enhance neural recording technology and amplifiers in them are also discussed.
