The most versatile neurophysiological paradigms for the study of cognitive function in animals are those that involve recording the activity of neurons in awake and behaving monkeys. Techniques for recording in behaving monkeys were originally developed by Herbert Jaspers and colleagues (Jasper et al., 1960) and elaborated by Edward Evarts (Evarts, 1966; Evarts, 1968) in the 1960s. Conventional recording methods, based on these early developments, employ single movable sharp electrodes to isolate single cells in regions of interest. Cells must be recorded serially over many weeks to accumulate enough data to characterize the population of cells under study. More recently, systems that permit several sharp electrodes-from approximately 2 to 16-to be independently positioned have improved the yield and allow the activity of several cells to be monitored simultaneously. Recordings of this kind, however, are generally restricted to a single cortical or subcortical site and can be maintained only for a short time.
