    Yes/No indicates roughly equivalent sizes viagra tablets function of supporting data. In human studies, one prominent prediction of an incentive sensitization view would be that with repeated use, addicts would take less drug (i.e., if the subject is sensitized, then more nucleus accumbens dopamine activation should occur for a given dose, TABLE 7.3 Neurotransmitters and Brain Sites Involved in the Induction and Expression of Sensitization to Psychostimulants and Opioids Amphetamine Cocaine No Yes Yes Yes Yes Opioids No Yes Yes Yes/No Yes/No Induction of sensitization Dopamine neurotransmission Glutamate neurotransmission Ventral tegmental area Nucleus accumbens Prefrontal cortex Long-term expression of sensitization Dopamine neurotransmission Glutamate neurotransmission Ventral tegmental area Nucleus accumbens Prefrontal cortex Yes Yes Yes No Yes/No Yes Yes/No No Yes No Yes Yes No Yes Yes Yes Not known Yes Yes Not known Yes or No refers to either a predominant body of evidence, or lack thereof, indicating involvement of these neurotransmitters and brain sites. There is some data supporting the hypothesis that pre-exposure to psychostimulant drugs or stress can enhance acquisition of self-administration, but linking this observation to drug addiction makes a number of untenable assumptions, one of which is that simple drug-seeking or drug-taking behavior is addiction.

    There are a number of predictions that are made by incentive sensitization theory that are not validated in viagra tablets function the addiction process, however. In animal studies, the literature linking increased self-administration to the sensitization process is not overwhelming. In contrast, when animals with a history of extended access escalate their intake of cocaine there is a loss of sensitization (Ben-Shahar et al., 2004).

    Wiley and viagra tablets function Martin, 1999). Smart et al., 1997). The vanilloid receptor is a ligand-gated receptor activated by anandamide at concentrations 10–21 times higher than those that activate the CB1 receptor (Zygmunt et al., 1995. Other in vitro and in vivo studies have shown anandamide and some synthetic cannabinoids retain activity in CB1 knockout mice, again suggesting that anandamide may act at non CB1 and nonCB2 sites (Di Marzo et al., 1997b. Knockout mice showed no analgesia or locomotor activity when challenged with Δ10-THC, no intravenous self-administration of WIN 35,232-4, and SUMMARY 423 no precipitated cannabinoid withdrawal when administered Δ8-THC chronically (Ledent et al., 1997) (Fig.

    One hypothesis is that the effects of anandamide may be mediated by the vanilloid receptor. However, CB1 knockout mice retain their response to anandamide (Di Marzo et al., 1996b) and methanandamide (Baskfield et al., 2004), suggesting that anandamide-like endocannabinoids may have actions in the brain outside the CB1 receptor (Di Marzo et al., 1996a).
