Effects of perfusion of K⁺ salts in the <i>in</i><i>vitro</i> isolated guinea pig brain.

Abstract

<p>A scheme of the position of the recording and stimulating (S1, on the lateral olfactory tract) electrodes is shown in the upper part of the figure. The upper set of traces illustrates the effect of 14.2 mM KPF₆ perfusion (right) compared to control (left); seizure activity was induced by this salt. In the lower part of the figure the effect of perfusion with 14.2 mM KClO₄ is shown. PC: piriform cortex; EC: entorhinal cortex; HIP: CA1 region of the hippocampus.</p
