A COMMUTATOR suitable for long-term recording and /or stimulation in unanaesthetised and unrestrained animals, especially rodents, is described. The device compensates for movements of tbe animal relative to stationary equipment, may be simply and inexpensively constructed and allows reliable low-noise operation of up to ten channels simultaneously. One of the technical problems common to all stimulation and recording experiments using unanaesthetised and unrestrained animals concerns the means… CONTINUE READING
