  - The contribution of the various hippocampal regions to the maintenance of epileptic
    activity, induced by stimulation of the perforant path or commissural system,
    was examined in the awake rat. Combination of multiple-site recordings with silicon
    probes, current source density analysis and unit recordings allowed for a high
    spatial resolution of the field events. Following perforant path stimulation,
    seizures began in the dentate gyrus, followed by events in the CA3-CA1 regions.
    After commissural stimulation, rhythmic bursts in the CA3-CA1 circuitry preceded
    the activation of the dentate gyrus. Correlation of events in the different subregions
    indicated that the sustained rhythmic afterdischarge (2-6 Hz) could not be explained
    by a cycle-by-cycle excitation of principal cell populations in the hippocampal-entorhinal
    loop. The primary afterdischarge always terminated in the CA1 region, followed
    by the dentate gyrus, CA3 region and the entorhinal cortex. The duration and pattern
    of the hippocampal afterdischarge was essentially unaffected by removal of the
    entorhinal cortex. The emergence of large population spike bursts coincided with
    a decreased discharge of interneurons in both CAI and hilar regions. The majority
    of hilar interneurons displayed a strong amplitude decrement prior to the onset
    of population spike phase of the afterdischarge. These findings suggest that (i)
    afterdischarges can independently arise in the CA3-CA1 and entorhinal-dentate
    gyrus circuitries, (ii) reverberation of excitation in the hippocampal-entorhinal
    loop is not critical for the maintenance of afterdischarges and (iii) decreased
    activity of the interneuronal network may release population bursting of principal
    cells. @eng
