“…Indeed, several studies report data incompatible with the hypothesis that histamine exerts a simple overall inhibition on reward through a modulation of the mesolimbic dopamine system. For example, intraaccumbal histamine and systemic administration of the histamine precursor histidine were shown to be rewarding in the place-conditioning paradigm in both rats and fish (Hasenohrl et al 2001;Coelho et al 2001). The administration of histamine also increased locomotor activity and dopamine release in the nucleus accumbens, both effects typically induced by addictive drugs (Kalivas 1982;Fleckenstein et al 1993;Galosi et al 2001).…”

“…However, it was found that the administration of histamine in the nucleus accumbens causes one-trial conditioned place preference in rats (Hasenohrl et al 2001). Moreover, histidine produces place-conditioning in the gold fish (Coelho et al 2001). Finally, the intracerebroventricular injection of histamine increases locomotor activity and dopamine release in the nucleus accumbens (Kalivas 1982;Fleckenstein et al 1993;Galosi et al 2001).…”

The functional role of histamine (HA) in zebrafish brains was studied. Zebrafish did not display a clear circadian variation in brain HA levels. Loading of zebrafish with L-histidine increased HA concentration in the brain. A single injection of the histidine decarboxylase (HDC) inhibitor, a-fluoromethylhistidine (a-FMH), gave rise to a rapid reduction in zebrafish brain HA. Low HDC activity in the brain after injections verified the effect of a-FMH. A reduction in the number of histaminergic fibres but not neurones and an increased expression of HDC mRNA was evident after a-FMH. Automated behavioural analysis after a-FMH injection showed no change in swimming activity, but abnormalities were detected in exploratory behaviour examined in a circular tank. No significant behavioural changes were detected after histidine loading. The time spent for performance in the T-maze was significantly increased in the first trial 4 days after a-FMH injections, suggesting that lack of HA may impair long-term memory. The rostrodorsal telencephalon, considered to correspond to the mammalian amygdala and hippocampus in zebrafish, is densely innervated by histaminergic fibres. These results suggest that low HA decreases anxiety and/or affects learning and memory in zebrafish, possibly through mechanisms that involve the dorsal forebrain.

“…Some studies describe the inhibitory effects of HA on learning and memory processes (10,11), while others have provided evidence that HA plays a role in reinforcement and mnemonic processes (12,13). A relationship between the NHS and anxiety has been suggested in studies of the behavior of fish (3,14) and rodents (15,16).…”

0.05, Kruskal-Wallis test), or at the dose of 500 mg/kg (OAE: 5.27 ± 0.73, 4.87 ± 0.66; OAT: 63.93 ± 11.72, 63.58 ± 10.22; P > 0.05, Fisher LSD test). At T2, LH-LH animals did not reduce open-arm activity (OAE and OAT) at the dose of 200 mg/kg (T1: 4.87 ± 0.66, T2: 5.47 ± 1.05; T1: 63.58 ± 10.22; T2: 49.01 ± 8.43 for OAE and OAT, respectively; P > 0.05, Wilcoxon test) or at the dose of 500 mg/kg (T1: 4.80 ± 1.60, T2: 4.70 ± 1.04; T1: 51.55 ± 12.10, T2: 43.88 ± 10.64 for OAE and OAT, respectively; P > 0.05, Fisher LSD test), showing an inability to evoke memory 24 h later. These data suggest that LH does not act on anxiety but does induce a state-dependent memory retrieval deficit in mice.]]>
