To study the role of afferent input frequency on cortical activation dynamics, the electrical activity of in vitro neocortex slices was imaged during white-matter electrical stimulation. ...
In contrast, repetitive stimulation in the ␥ frequency range (ϳ40 Hz) rapidly restrained the area of excitation to a small columnar site directly above the stimulating electrode. ...
In such models, spatiotemporal patterns of cortical activation depend solely on input dynamics and on the linear integrative properties of the target neurons. ...
