Abstract:
Workingmemory has been linked to elevated activity in single neurons in monkeys, as well as to oscillatory phenomena in the human EEG. To understand the relation between these findings, we explore here whether working-memoryoscillations can also be observed in monkeycortex. We indeed found working-memoryrelatedoscillations in the thetafrequency band in monkeyvisualcortex, which were correlated to monkeys’ behavioral performance on a contrast discrimination task. We discuss possible functional interpretations of this finding.
