Abstract :
Theta rhythm dependent activity of rat hippocampal cells "theta phase precession" was elucidated based on the hypothesis that theta phase coding enables instantaneous acquisition of experienced events. By using a neural network model of theta phase coding we demonstrate high acquisition abilities of spatial and temporal events. A theoretical prerequisite for this computational power predicts a hippocampal-entorhinal network mechanism to regulate theta phase coding.
