A low-noise amplifier like the DAM50 is an excellent choice for EEG recording in rodents. WPI’s amplifiers were engineered for the bio-medical researcher. While 20-30μV of noise is common in bio-amplifiers, WPI’s DAM series amplifiers generate 0.4μV RMS (root mean squared) at 0.1-100Hz. (That’s equal to about 2μV peak to peak.) This setup shows one way such recordings could be made. The RC1 electrode works well for rats, and the EP1 is more suitable for mouse cranial application.
Find out what you need to know before you buy your next amplifier. WPI amplifiers consistently outperform the cheaper competitors, because WPI reduces the schott noise, which provides a cleaner output. Read this article to learn how an amplifier works so you will know what to look for when you are buying your next amplifier.
Dri-Ref™ reference electrodes were developed by WPI to have extremely low electrolyte leakage properties, hence the name “Dri-Ref.” In addition to this key feature, these electrodes exhibit stable and reproducible potential and low resistance.
