Chronically recording with a multi-electrode array device in the auditory cortex of an awake ferret.

It is known that anesthesia depresses neural activity and inhibits cortico-cortical interactions and cortical output. Hence, it is important to record from awake animals in order to better understand the full dynamic range of neural responses. We have developed a preparation for chronic, multi-electrode physiological recording in the cortex of the awake ferret. This paper discusses several of the advantages and disadvantages of the technique as well as procedures used to overcome potential complications associated with chronic implants in the ferret. Our solutions are well suited to the special species requirements, yet are also easily generalizable to other species.
