Abstract:Spatial distribution of theta activity was investigated in the dorsal hippocampal formation and overlying neocortex of the urethaneanesthetized rat. Laminar phase profiles from semi-microelectrode penetrations showed approximately 180° phase shifts combined with small amplitude values in stratum radiatum of CA1, in stratum moleculare of the dentate gyrus and in layer V/VI of the cingulate cortex at theta peak frequency. Evidence has been presented that layers of neurons in CA1, in the dorsal granular layer and in the cinguate cortex are the sources of dipole-like theta field potentials. A strong linear relationship between the neuronal theta sources in hippocampal CA1, dendate area and cingulate cortex was found.
