Figure 2

Schematic representation of the functional blocks of the SBF model. The oscillator block OSC contains N osc neural oscillators that constitute the time base for the entire interval timing network. The memory block MEM stores the criterion time, c, and the “state” of the brain at the reinforcement time w(k,c), with k=1,…,N osc . The decision and output block OUT compares the current state of the oscillators in OSC, w(k,t), with the memorized reference state w(k,c) at reinforcement time and produces a smooth output proportional to the “closeness” of the two states. The neuromodulator block MOD mimics the global effect of DA and ACh neuromodulators.
