Using impedance conversion as a recording technique, heartbeat patterns were established for intact adult honey bee workers during rest and during nectar feeding and locomotion, activities that both result in accelerating heartbeat. Heartbeat patterns were then described separately for bees in which assumed neural regulation was disrupted (the ventral nerve(More)
The effects of hypoxia on the transmembrane potential of dog Purkinje cells in isolated, superfused fiber bundles pretreated with ouabain were studied. Cells stimulated electrically at 93/min were exposed to ouabain, 2.1 X 10(-7) M, until the magnitude of phase 4 depolarization increased to 7-12 mV. Arrhythmias did not occur. Following a 10-min washout(More)
