HF stimulation of a network of AHH model neurons.
The critical value for repetitive activity in a AHH model neural network, as a function of the probability of excitatory synaptic connections . The mean (thick black) over simulations, 1 (solid black) and 2 (thin black) SEM (standard error of the mean, standard deviation of ) are shown. Single cell critical values of ( and ) are identified (see text for description). in units of .
