Material and methods

Adult rats (250–300 g) were decapitated under deep methohexital anaesthesia and the brains were rapidly removed to ice-cold (4 °C) artificial cerebrospinal fluid (ACSF). The cerebellum was removed and a cut was made to divide the two cerebral hemispheres. Combined amygdala-hippocampus–cortex slices containing the temporal cortex, the perirhinal cortex, the entorhinal cortex, the subiculum, the dentate gyrus, the hippocampus, as well as the amygdala (500 μm) were cut in a nearly horizontal plane. Up to two different slices from each side were collected in a preparation. Slices were stored at 28 °C in ACSF, which contained (in mm) NaCl, 124; KCl, 4; CaCl2, 1.0; NaH2PO4, 1.24; MgSO4, 1.3; NaHCO3, 26; glucose, 10 (pH 7.4), oxygenated with 95% O2 and 5% CO2 for > 1 h. After 30-min incubation, CaCl2 was elevated to 2.0 mmol/L. Slices were individually transferred to an interphase recording chamber, placed on a transparent membrane, illuminated from below and continuously perfused (1.5–2 mL/min) with carbogenated ACSF at 32 °C. A warmed, humified 95% O2 and 5% CO2 gas mixture was directed over the surface of the slices.
