Theta-frequency resonance in frequency, and the resonant frequency is just below the natuhippocampal CA1 neurons in vitro demonstrated by sinusoidal ral oscillation frequency for a linear system. However, resocurrent injection. J. Neurophysiol. 79: 1592Neurophysiol. 79: -1596Neurophysiol. 79: , 1998. Sinusoinance at the theta frequency has not been clearly demondal currents of various frequencies were injected into hippocampal strated in hippocampal neurons (cf. Yu and Leung 1993). CA1 neurons
