The neurons release increased quantities of glutamate, which may act on up-regulated receptors.

Moreover, the prodynorphin gene is and amphetamine, it also initiating a cascade of homeostatic expressed in the striatum in D1 receptor bearing cells (58). One of these adaptations is adenylyl cyclase to produce cAMP, which in turn activates induction of dynorphin peptides (Fig. Dynorphin gene regulation by psychostimulants: implications for central motive states. Cocaine and amphetamine increase levels of dopamine in the nucleus accumbens and dorsal striatum. D1 receptor stimulation by dopamine leads to activation of the cAMP pathway, phosphorylation of CREB and ultimately the transcription of CRE-regulated genes such as c-fos and prodynorphin. Glutamate, via the NMDA receptor, as well as L-type calcium channels similarly contribute to CREB phosphorylation and CRE-driven gene expression in these dopaminoceptive neurons. Release of dynorphin inhibits dopamine release by binding to its presynaptic target, the opiate receptor, on DA nerve terminals. The dynorphin negative-feedback mechanism for controlling dopamine levels also contributes to aversive feelings and dysphoria due to its actions at the opiate receptor.

Associative learning also appears to play a role in psy- of the angiogenic and aversive aspects of drug withdrawal. If, for example, a rat is taken Increased release of CRF, particularly in the central nucleus from its home cage to a novel 'test' cage for intermittent of the amygdala, occurs during withdrawal from ethanol, amphetamine injections, the sensitized locomotor response opiates, cocaine, and cannabinoids. CRF antagonists have to a challenge dose is much greater if the challenge is also reversed at least some of the aversive effects of cocaine, given in that test cage than if given in a different environ- ethanol, and opiate withdrawal in laboratory animals.

As described, conditioned Drug-induced changes in expression of transcription factors responses to drug-associated cues persist far longer than may lead to the altered expression of specific target genes, withdrawal symptoms (36), and can occur despite years of which in turn may affect both homeostatic adaptations and abstinence from drugs.
