WebHippocampal Theta Rhythm in Rodents. The rodent hippocampal theta rhythm is a 4–12 Hz, large amplitude local field potential oscillation that is prominent during exploration and … WebAnd potentially key to these functions is a physiological signature called the theta rhythm: a 4–8Hzoscillation in the local field potential (LFP) that was first characterized in rodents in the 1930s (Box 1). In subsequent decades, a vast theoretical and empirical enterprise has grown around the theta rhythm.
