Fig. 5From: Stabilization of Memory States by Stochastic Facilitating SynapsesRange of bistability is enhanced with facilitating synapses and reduced withdepressing synapses. a Low threshold, with β 2 =0.301. b High threshold with β 2 =1.001. a, b White region, all models (with static, facilitating and depressing synapses)are bistable; yellow region, models with static or facilitating synapses arebistable; orange region, only models with facilitating synapses are bistable;black region, no models are bistableBack to article page
