Interactions between antidromic activation and burst activity in model thalamic neuron. (a) Burst spiking in the cell body with no extracellular stimulation. Distribution of burst and Poisson inputs were indicated in Methods. g_exc = 0.2 nS and g_inh = 0.06 nS. (b) Voltage responses in the soma with 20 Hz, 100 Hz, and 180 Hz cathodic stimulation at electrode position II. (c) CV of the somatic (left) and axonal (right) firing as a function of f_pulse during cathodic stimulation. (d) Somatic (left) and axonal (right) firing rate as a function of f_pulse during cathodic stimulation. (e) CV of the somatic and axonal (right) firing as a function of f_pulse during anodic stimulation. (f) Somatic (left) and axonal (right) firing rate as a function of f_pulse during anodic stimulation. The dotted line in (c)-(f) indicated the CV or firing rate without extracellular stimulation. Three positions of the electrode were indicated in figure 5(a). Pulse amplitude was 1.2I_th, and pulse width was 0.1 ms.
