Sensitization to repeated doses of psychostimulants is thought to be an important component underlying the addictive process in humans [1] [2] [3] [4]. In all vertebrate animal models, including humans [5], and even in fruit flies, sensitization is observed after repeated exposure to volatilized crack cocaine [6]. In vertebrates, sensitization is thought to be initiated by processes occurring i...
Short- and long-term synaptic facilitation induced by serotonin at Aplysia sensory-motor (SN-MN) synapses has been widely used as a cellular model of short- and long-term memory for sensitization. In recent years, a distinct intermediate phase of synaptic facilitation (ITF) has been described at SN-MN synapses. Here, we identify a novel intermediate phase of behavioral memory (ITM) for sensitiz...
Repeated exposure to psychostimulants induces a long-lasting enhancement of locomotor activity called behavioral sensitization, which is often reinforced by stress after drug withdrawal. The mechanisms underlying these phenomena remain elusive. Here we explored the effects of acute stress 3 or 14 days after the cessation of chronic cocaine treatment on the expression of locomotor sensitization ...
