Five-minute sampling through CA3 at 5000 V m⁻¹ (38 µA current). The bath solution is HBSS with 150 µmol L⁻¹ YGGFL and IS with or without inhibitors as follows: Experiment A, no inhibitors; B, includes inhibitors (µmol L⁻¹): thiorphan (15), GEMSA (210), captopril (25); C, as B plus puromycin (20); D, as C plus bestatin (100).
