“…Specifically, an age-related elevation in novelty-seeking (see Adriani et al 1998;Spear 2000), which is known to be a risk factor for vulnerability to drugs of abuse (see Bardo et al 1996), may account for the early onset of nicotine preference shown by mice in the present study. More work would be needed to further characterize, in laboratory rodents, the patterns of spontaneous consumption of drugs of abuse during adolescence (see e.g.…”

(10 mg/l). After a 6-day period, a fading study was carried out, in which nicotine concentration was reduced to 7 mg/l (days 7-9) and 5 mg/l (days 10-12), to assess whether animals would compensate by increasing their intake from the nicotine solution. In Experiment 2, psychopharmacological effects on locomotion induced by the nicotine solution (0, 10, 30 mg/l) Recent research has emphasized that adolescence is associated with patterns of temporary deviance (Arnett 1992) and the use of various kinds of psychoactive agents (Mathias 1996). Drug abuse in adolescents ranging from 11-12 to 17-18 years of age is likely to start with tobacco smoking, which can be followed by marijuana and/or 1991;Breslau et al. 1993;Nides et al. 1995;Kandel and Chen 2000). Despite the social and scientific importance of deepening our knowledge of this issue (see e.g. Colby et al. 2000), there have been very few investigations on the psychobiological factors contributing to the specific adolescence-related willingness to experience various psychoactive drugs (for a review, see Laviola et al. 1999;Spear 2000). For the purpose of laboratory studies, a suitable animal model of human adolescence is available in rodents. Namely, periadolescence is classically defined as the ontogenetic period that encompasses the week preceding the onset of puberty and the first few days thereafter (Spear and Brake 1983). Periadolescent rodents differ markedly from adults in their spontaneous behavioral repertoire (Cirulli et al. 1996;Terranova et al. 1993;Meaney and Stewart 1981;Panksepp 1981). In fact, elevated levels of novelty seeking and a reduced behavioral and hormonal response to stress (Adriani et al. 1998;Adriani and Laviola 2000) are exhibited by animals around this age. A characteristic hyporesponsivity to the effects of an acute administration of psychostimulants (Spear and Brake 1983;Laviola et al. 1995;Bolanos et al. 1998;Adriani and Laviola 2000), a peculiar pattern of behavioral sensitization following repeated drug exposure (Laviola et al. 1995(Laviola et al. , 2001Adriani et al. 1998), as well as a weak drug-induced place conditioning profile (Adriani et al. 1998;Bolanos et al. 1996Bolanos et al. , 1998 but see Campbell and Spear 2000), are also reported. Based on these findings, an increased vulnerability to the addictive properties of abused drugs has been suggested to be typical of adolescence in both humans and animals models (see Laviola et al. 1999).In the present study, we were interested in nicotine, which beside being the main psychoactive compound implied in tobacco smoking, also shares most of the characteristics of other addictive drugs (Corrigall et al. 1992(Corrigall et al. ,1994Pontieri et al. 1996;Merlo-Pich et al. 1997;Stolerman 1999). Nicotine's effects in mice have been shown to be highly dependent on the genetic background (see Marks et al. 1989;Robinson et al. 1996). However, the interaction between the pharmacological effects and the incentive properties of nicotine during the adolescent period has been largel...

“…It has been argued that people who score high on NS scales may include those with high impulsivity, and it has been further suggested that substance abusing subjects have higher NS scores than do controls (reviewed in Bardo et al 1996). Although higher allele frequencies of the 3 and 6 alleles compared to published data were found in a sample of alcoholics, no control group was used in this study (George et al 1993).…”

“…In addition, abnormal novelty-seeking behavior has been linked to many neuropsychiatric disorders. For example, high novelty-seekers are more susceptible to drugs of abuse than low novelty-seekers [51,52]. Reduced novelty-seeking is known to be associated with autism [6,7] and Alzheimer's disease [53].…”

Toll-Like Receptor 4 Deficiency Causes Reduced Exploratory Behavior in Mice Under Approach-Avoidance Conflict

Abnormal approach-avoidance behavior has been linked to deficits in the mesolimbic dopamine (DA) system of the brain. Recently, increasing evidence has indicated that toll-like receptor 4 (TLR4), an important pattern-recognition receptor in the innate immune system, can be directly activated by substances of abuse, resulting in an increase of the extracellular DA level in the nucleus accumbens. We thus hypothesized that TLR4-dependent signaling might regulate approach-avoidance behavior. To test this hypothesis, we compared the novelty-seeking and social interaction behaviors of TLR4-deficient (TLR4 -/-) and wild-type (WT) mice in an approach-avoidance conflict situation in which the positive motivation to explore a novel object or interact with an unfamiliar mouse was counteracted by the negative motivation to hide in exposed, large spaces. We found that TLR4 -/-mice exhibited reduced novelty-seeking and social interaction in the large open spaces. In less stressful test apparatuses similar in size to the mouse cage, however, TLR4 -/-mice performed normally in both novelty-seeking and social interaction tests. The reduced exploratory behaviors under approachavoidance conflict were not due to a high anxiety level or an enhanced fear response in the TLR4 -/-mice, as these mice showed normal anxiety and fear responses in the open field and passive avoidance tests, respectively. Importantly, the novelty-seeking behavior in the large open field induced a higher level of c-Fos activation in the nucleus accumbens shell (NAcSh) in TLR4 -/-mice than in WT mice. Partially inactivating the NAcSh via infusion of GABA receptor agonists restored the novelty-seeking behavior of TLR4 -/-mice. These data suggested that TLR4 is crucial for positive motivational behavior under approach-avoidance conflict. TLR4-dependent activation of neurons in the NAcSh may contribute to this phenomenon.
