Abstract	Abstract The effects of intracellular Cl − diffusion and hyperpolarizing current pulses on inhibitory postsynaptic potentials (IPSPs) and the transmembrane theta rhythm of CA1–CA3 pyramidal neurons were tested in urethanized and curarized rats. Cl − diffusion and hyperpolarizing currents decreased the amplitude of IPSPs evoked by fornix stimulation without modifying the θ rhythm amplitude and phase. The membrane conductance was typically 22–46% higher at the positive than negative intracellular θ peaks. Results indicate that in curarized rats excitatory postsynaptic potentials were the main components of intracellular θ without an important participation of IPSPs in θ rhythm genesis.
