The effect of stress hormone corticosterone on hippocampal neurons delayed rectified potassium currents was probed.
The potassium currents of rat hippocampal neurons in primary culture were measured with patch clamp whole-cell recording.
It showed that the amplitudes of the potassium currents in hippocampal neurons decreased. However, the threshold potential of potassium currents increased.
It is speculated that excessive corticosterone may hurt the hippocampal neurons via its effects on the potassium currents of rat hippocampal cells.
