Fig. 6. The current pulses integrated from Ca²⁺-induced potentiation at glutamatergic and GABAergic synapses improve spike encoding. (A) Superimposed waveforms of spikes evoked by currents integrated from GABAergic and glutamatergic synaptic transmission in the control (left panel) and with adenophostin-A-induced synaptic potentiation (right). The integrative effect of adenophostin-A on neuronal encoding is an increase in the number of sequential spikes. (B) SDST values of sequential spikes under control and adenophostin-A infusion, in which SDST is significantly different for spike 3 (P<0.01).
