Electrophysiological characteristics of hippocampal CA1 neurons after spreading depression-triggered epileptic activity in brain slices
Introduction: A close link between spreading depression (SD) and several neurological diseases such as epilepsy could be demonstrated in many experimental studies. Epilepsy is among the most common brain disorders. Despite a large number of investigations, its mechanisms have not been yet well elucidated. Hippocampus is one of the important structures involved in seizures. The aim of this st...
متن کاملDynamics of epileptiform activity in mouse hippocampal slices
Increase of the extracellular K( + ) concentration mediates seizure-like synchronized activities in vitro and was proposed to be one of the main factors underlying epileptogenesis in some types of seizures in vivo. While underlying biophysical mechanisms clearly involve cell depolarization and overall increase in excitability, it remains unknown what qualitative changes of the spatio-temporal n...

متن کاملElectric field suppression of epileptiform activity in hippocampal slices.
1. The effects of relatively small external DC electric fields on synchronous activity in CA1 and CA3 from transverse and longitudinal type hippocampal slices were studied. 2. To record neuronal activity during significant field changes, differential DC amplification was employed with a reference electrode aligned along an isopotential with the recording electrode. 3. Suppression of epileptifor...
متن کاملIntrinsic optical signals in rat hippocampal slices during hypoxia-induced spreading depression-like depolarization.
In interfaced rat hippocampal slices spreading depression (SD) and hypoxia-induced SD-like depolarization are associated with increased light reflectance and decreased light transmittance, indicating increased light scattering. By contrast, mild hypotonicity or electrical stimulation decrease light scattering, which is usually taken to be caused by cell swelling. This difference has been attrib...
