Abstract
The influence of CA1 hippocampal field on theta-activity production de pending on the efficiency of CA1 synaptic inputs was studied in freely moving rats during their orienting behaviour. The long-term potentiat ion of Shaffer collaterals resulted in an increase in regularity of th e theta activity due to a decrease in its amplitude-frequency modulati on and variability of the waveform from cycle to cycle. Additionally, an increase in amplitude and decrease in frequency were observed. The results reveal the influence of CA1 field on the work of the septal th eta activity oscillator.
