(C) GABA-mduced hyper- polarization of B neurons and depolarization of A neurons are associated with the increases in membrane conductance. Two intracellular electrodes were used in these experiments; one for recording membrane potential (shown in figure), and a second for injecting negative current pulses. Current pulses: neuron RBI. -1 nA; neuron RA1, -2 nA. Scale bars = 10 mV, 2 s. (D) Effect of 2 nM GABA on neurons LB1 and RAI in seawater. Note the initial smooth hyperpolanzation and the delayed appearance of inhibitory postsynaptic potentials (shown by arrow) in Bl neuron initiated by A neurons. The drawings above the record indicate observed activity of the head before and after GABA application. Before application skin folds were closed and buccal cones were withdrawn; after application skin folds were open and buccal cones were partially extruded. Scale bars = 20 mV, 2 s. J.
