Abstract
Rodent behavioral studies have largely focused on male animals, which has limited the generalizability and conclusions of neuroscience research. Working with humans and rodents, we studied sex effects during interval timing that requires participants to estimate an interval of several seconds by making motor responses. Interval timing requires attention to the passage of time and working memory for temporal rules. We found no differences between human females and males in interval timing response times (timing accuracy) or the coefficient of variance of response times (timing precision). Consistent with prior work, we also found no differences between female and male rodents in timing accuracy or precision. In female rodents, there was no difference in interval timing between estrus and diestrus cycle stages. Because dopamine powerfully affects interval timing, we also examined sex differences with drugs targeting dopaminergic receptors. In both female and male rodents, interval timing was delayed after administration of sulpiride (D2-receptor antagonist), quinpirole (D2-receptor agonist), and SCH-23390 (D1-receptor antagonist). By contrast, after administration of SKF-81297 (D1-receptor agonist), interval timing shifted earlier only in male rodents. These data illuminate sex similarities and differences in interval timing. Our results have relevance for rodent models of both cognitive function and brain disease by increasing represenation in behavioral neuroscience.

Abstract
The state-dependent memory defines as a state that the retrieval of recently obtained information may be potential if the subject exists in a similar physiological situation as for the period of the encoding stage. Studies revealed that exogenous and endogenous compounds could induce state-dependent memory. The state-dependent memory made it probable to differentiate the effects of drugs per se on learning from the effects due to alterations in drug state during the task. Studies proposed the role of regions beyond the limbic formation and illustrated that state-dependent memory produced by various neurotransmitter systems and pharmacological compounds. Our review of the literature revealed that: (a) re-administration of drugs on the same state induce state-dependent memory; (b) many neurotransmitters induce endogenous state-dependent memory; (c) there are cross state-dependent learning and memory between some drugs; (d) some sites of the brain including the CA1 areas of the hippocampus, central nucleus of the amygdala (CeA), septum, ventral tegmental area (VTA), and nucleus accumbens (NAC) are involved in state-dependent memory.

Abstract
RATIONALE Treatment of bipolar disorder (BPD) with lithium and olanzapine concurrent administration is a major medicine issue with the elusive neurobiological mechanisms underlying the cognitive function. OBJECTIVE To clarify the precise mechanisms involved, the possible role of the hippocampus (HPC) and prefrontal cortical (PFC) NMDA receptors and CAMKII-CREB signaling pathway in the interactive effects of lithium and olanzapine in memory consolidation was evaluated. The dorsal hippocampal CA1 regions of adult male Wistar rats were bilaterally cannulated and a step-through inhibitory avoidance apparatus was used to assess memory consolidation. The changes in p-CAMKII/CAMKII and p-CREB/CREB ratio in the HPC and the PFC were measured by Western blot analysis. RESULTS Post-training administration of lithium (20, 30, and 40 mg/kg, i.p.) dose-dependently decreased memory consolidation whereas post-training administration olanzapine (2 and 5 mg/kg, i.p.) increased memory consolidation. Post-training administration of certain doses of olanzapine (1, 2, and 5 mg/kg, i.p.) dose-dependently improved lithium-induced memory impairment. Post-training administration of ineffective doses of the NMDA (10-5 and 10-4 μg/rat, intra-CA1) plus an ineffective dose of olanzapine (1 mg/kg, i.p.) dose-dependently improved the lithium-induced memory impairment. Post-training microinjection of ineffective doses of the NMDA (10-5 and 10-4 μg/rat, intra-CA1) dose-dependently potentiated the memory improvement induced by olanzapine (1 mg/kg, i.p.) on lithium-induced memory impairment which was associated with the enhancement of the levels of p-CAMKII and p-CREB in the HPC and the PFC. Post-training microinjection of ineffective doses of the noncompetitive NMDA receptor antagonist, MK-801 (0.0625 and 0.0125 μg/rat, intra-CA1), dose-dependently decreased the memory improvement induced by olanzapine (5 mg/kg, i.p.) on lithium-induced memory impairment which was related to the reduced levels of HPC and PFC CAMKII-CREB. CONCLUSION The results strongly revealed that there is a functional interaction among lithium and olanzapine through the HPC and the PFC NMDA receptor mechanism in memory consolidation which is mediated with the CAMKII-CREB signaling pathway.

Abstract
In this study, we examined the effect of bilateral intra-basolateral amygdala (intra-BLA) microinjections of dopamine receptor agents on amnesia induced by a β-carboline alkaloid, harmaline in mice. We used a step-down method to assess memory and then, hole-board method to assess exploratory behaviors. The results showed that pre-training intra-BLA injections of dopamine D1 receptor antagonist and agonist (SCH23390 (0.5μg/mouse) and SKF38393 (0.5μg/mouse), respectively) impaired memory acquisition. In contrast, pre-training intra-BLA injections of dopamine D2 receptor antagonist and agonist (sulpiride and quinpirole, respectively) have no significant effect on memory acquisition. Pre-training intra-peritoneal (i.p.) injection of harmaline (1mg/kg) decreased memory acquisition. However, co-administration of SCH 23390 (0.01μg/mouse) with different doses of harmaline did not alter amnesia. Conversely, pre-training intra-BLA injection of SKF38393 (0.1μg/mouse), sulpiride (0.25μg/mouse) or quinpirole (0.1μg/mouse) reversed harmaline (1mg/kg, i.p.)-induced amnesia. Furthermore, all above doses of drugs had no effect on locomotor activity. In conclusion, the dopamine D1 and D2 receptors of the BLA may be involved in the impairment of memory acquisition induced by harmaline.

Pharmacol Biochem Behav 2014; 122:203-11.

Abstract
PURPOSE The aim of this study was to investigate the interactive effect of lithium and atorvastatin on cognitive performance and the role of NO as a potential mechanism involved in this interaction. MATERIALS AND METHODS Memory performance was evaluated in a two-trial recognition Y-maze test and a step-through passive avoidance task in mice. Lithium (5, 10, 20 or 40 mg/kg, i.p.) and atorvastatin (1 mg/kg, p.o.) were administered 1 h before each trial, L-NAME, a non-specific NO synthase inhibitor (3, 10 mg/kg, i.p.); aminoguanidine, a specific inducible NO synthase (iNOS) inhibitor (100 mg/kg); and L-arginine, a NO precursor (750 mg/kg) were administered 30 min before training sessions. The level of plasma NO end-products (NOx) was determined using Griess reagent protocol. RESULTS 1) Lithium (40 mg/kg) impaired the acquisition of spatial recognition memory; 2) lithium did not affect the retrieval phase of spatial memory; 3) atorvastatin (1 mg/kg) significantly impaired the memory performance, when co-administered with the sub-effective dose of lithium (10 mg/kg), but did not affect the status when administered with lithium (5 mg/kg); 4) L-NAME (10 mg/kg) and aminoguanidine (100 mg/kg) dramatically decreased memory performance in mice received sub-effective doses of both lithium (5 mg/kg) and atorvastatin (1 mg/kg); 5) L-arginine (750 mg/kg) improved the memory acquisition in mice administered lithium (10 mg/kg) and atorvastatin (1 mg/kg); 6) lithium did not affect the cognitive performance in the passive avoidance test. All results were compatible and confirmed with in vitro determination of plasma NOx levels. CONCLUSIONS Lithium, dose dependently, impaired acquisition phase of spatial recognition memory. Lithium and atorvastatin co-administration impaired spatial recognition memory mediating by nitrergic pathway. In addition to L-arginine, our data from L-NAME and aminoguanidine also support the involvement of NO pathway in this interaction.

Lithium chloride disrupts consolidation of morphine-induced conditioned place preference in male mice: the nitric oxide/cyclic GMP signaling pathway. Behav Brain Res 2011; 219:240-7. [PMID: 21241742 DOI: 10.1016/j.bbr.2011.01.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2010] [Revised: 12/29/2010] [Accepted: 01/10/2011] [Indexed: 12/21/2022]
Abstract
Lithium effects on brain functions such as cognition, attention, learning and memory are well-established for ages; however, the way it affects these functions and its precise mechanism of action remains unknown. The purpose of this study was to determine the effects of lithium on the consolidation of morphine-associated conditioned place preference and the possible involvement of the NO/cGMP pathway. Using an unbiased conditioned place preference (CPP) model, the effects of lithium (1-100 mg/kg, i.p.), nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME) (5-100 mg/kg, i.p.), nitric oxide precursor L-arginine (50-150 mg/kg, i.p.) and phosphodiesterase inhibitor sildenafil (5-40 mg/kg, i.p.) on the consolidation of morphine-induced CPP were assessed. In addition, the possible interaction between lithium, L-arginine and sildenafil or subeffective doses of lithium and L-NAME on the consolidation of morphine-induced contextual memory was evaluated. NMRI mice were used in all studies. Lithium (5-30 mg/kg, i.p.), immediately after conditioning trials, significantly reduced the time spent by mice in the reward-paired compartment. Although post-training administration of L-arginine, sildenafil or L-NAME had no significant effect on the consolidation of CPP, concomitant administration of L-arginine (50-150 mg/kg) and sildenafil (5-10 mg/kg) with lithium (30 mg/kg) prevented the impairing effect of lithium. Also, co-administration of sub-effective doses of lithium (1 mg/kg) and L-NAME (5 mg/kg) disrupted consolidation of CPP. However, delayed administration of effective doses of lithium, which shows specific effect on memory consolidation, did not affect morphine-induced CPP. Lithium seems to inhibit consolidation of morphine-induced CPP and this impairing effect might be via nitric oxide/cyclic GMP pathway.

Abstract
We have previously shown lithium-induced state-dependent learning in a step-down inhibitory avoidance task. In the present study, the effects of intracerebroventricular injections of N-methyl-D-aspartate (NMDA) receptor agents on the lithium-induced state-dependent learning have been investigated. A single-trial step-down inhibitory avoidance task was used to assess memory in male Naval Medical Research Institute (NMRI) mice. The results showed that post-training lithium (10 mg/kg) decreased the step-down latency on the test day, which was reversed by pre-test administration of the same dose of the drug; indicating state-dependent learning induced by lithium. Pre-test administration of NMDA (0.0001, 0.001 and 0.01 microg/mouse, intracerebroventricular) could also substitute for pre-test lithium to reverse the decrease of the step-down latency induced by post-training lithium. Furthermore, pre-test co-administration of an ineffective dose of NMDA (0.00001 microg/mouse, intracerebroventricular.) with lower doses of lithium (1.25, 2.5 and 5 mg/kg, intraperitoneally.) synergistically reversed the decrease of the step-down latency. On the contrary, pre-test injections of NMDA receptor antagonist D-AP5 (0.25, 0.5, 1 and 2 microg/mouse, intracerebroventricular.) disrupted state-dependent learning induced by lithium. The results suggest that NMDA receptors may be involved, at least partly, in the lithium-induced state-dependent learning.

Abstract
Prepulse inhibition (PPI) of acoustic startle response is a valuable paradigm for sensorimotor gating processes. Previous research showed that acute administration of St. John's wort extract (500 mg/kg, p.o.) to rats caused significant disruption of PPI while elevating monoamines levels in some brain areas. The cause-effect relationship between extract-induced PPI disruption and augmented monoaminergic transmission was studied using different serotoninergic, adrenergic and dopaminergic antagonists. The effects of hypericin and hyperforin, as the main active constituents of the extract, on PPI response were also tested. PPI disruption was prevented after blocking the serotoninergic 5-HT1A and 5-HT2A, alpha-adrenergic and dopaminergic D1 receptors. Results also demonstrated a significant PPI deficit after acute treatment of rats with hyperforin, and not hypericin. In some conditions manifesting disrupted PPI response, apoptosis coexists. Electrophoresis of DNA isolated from brains of hyperforin-treated animals revealed absence of any abnormal DNA fragmentation patterns. It is concluded that serotoninergic 5-HT1A and 5-HT2A, alpha-adrenergic and dopaminergic D1 receptors are involved in the disruptive effect of St. John's wort extract on PPI response in rats. We can also conclude that hyperforin, and not hypericin, is one of the active ingredients responsible for St. John's wort-induced PPI disruption with no relation to apoptotic processes.
