Figure 7.
A random recurrent network without depressing synapses shows no counting behavior and weakly tuned amplitude selectivity. (A,B) Post-stimulus firing rates of each group of neurons in response to (A) repetitions of an optimal-strength stimulus and (B) a single stimulus of varying amplitude. (C,D) Confusability matrix indicated how distinguishable the network responses are for the successive repetitions of the same stimulus (C) or for a single stimulus of different amplitudes (D).
