INTRODUCTION
Endocannabinoid system (ECS) plays role in many physiological processes, including mood, learning and memory. It is also involved in the pathogenesis of anxiety and mood disorders, as well as neurodegenerative disorders (Hill and Gorzalka, 2009; Ranieri et al., 2016). ECS consists of the endogenous cannabinoids (endocannabinoids), cannabinoid receptors and the enzymes that synthesize and degrade endocannabinoids. The cannabinoid receptors (CB1 and CB2) belong to the class of G

, gonadal hormones are also assumed to have an influence on many cerebral function.
Finally, even though much of the evidence on gonadal-induced neuroplasticity, related to learning and memory processes, centers on the effect of estrogens, data related to neurotrophic actions of androgens also exist (Colciago et al., 2015).
Role of estrogens in memory processes
Many studies have suggested that estrogens have a role on many cognitive functions, including learning and memory (Gasbarri et al., 2008a

INTRODUCTION
Many aspects of the health benefits of exercise are known, such as those in endocrine and cardiovascular systems, as well as metabolic and developmental functions (Hughes et al., 1993; Ostergard et al., 2006; Labonte-Lemoyne et al., 2017; Lin and Lee, 2018). In recent years, scientific research has focused on the effects of exercise on the neurocognitive process. Exercise has been shown to improve learning and memory function by increasing neurogenesis and angiogenesis in the

Learning and memory are highly complex processes. Each is accompanied by changes in brain activity, including synaptic plasticity in the form of long-term potentiation (LTP) and LTD (Kemp and Manahan-Vaughan, 2007). Previous studies showed that NMDARs play an important role in synaptic plasticity (Hunt and Castillo, 2012), learning and memory (Li and Tsien, 2009), and epileptogenesis (Frasca et al., 2011). Changes in the NR2A to NR2B subunits ratio affect the

Endocannabinoids (eCBs) are involved in the hippocampal mechanisms of spatial learning and memory in rats. Although eCBs exert many of their actions on spatial learning and memory via CB1 receptors, the putative cannabinoid receptor GPR55 (expressed in the hippocampus, cortex, forebrain, cerebellum and striatum) seems to be also involved. To investigate the potential role of GPR55 in spatial learning and memory, Wistar rats received bilateral infusions of lysophosphatidylinositol (LPI, GPR55

Review | 15-January-2019
The development of molecular biology methods in the early 1980s led to a better understanding of the role of transcription factors in mammalian cells. The discovery that some transcription factors are critically important for cells to switch between different functional states was fundamental for modern molecular neurobiology. In the 1980s Leszek Kaczmarek proposed that, analogically to the cell cycle or to cell differentiation, long-term synaptic plasticity, learning, and memory should also

various brain injuries, it is still unknown whether DEX can directly protect against cognitive dysfunction induced by sevoflurane exposure, especially in developing brain. Notably, in the depression model of rats treated by chronic unpredictable mild stress, DEX is suggested to protect against learning and memory impairment caused by electroconvulsive shock in depressed rats, with the involvement of the NMDA receptor subunit 2B (NR2B)-ERK signaling pathway (Gao et al., 2016). In light of the above

alterations, which lead to behavioral abnormalities, including learning and memory impairment (Ahmed et al., 2008; Ritchie and Yeap, 2015). These hormones regulate the growth factor expression and synaptogenesis in learning and memory-related brain areas, including the hippocampus and cortex (Forrest and Vennström, 2000; Parent et al., 2011). The hippocampus appears to be more sensitive than the cortex to thyroid hormone depletion (Zhang et al., 2009; Parent et al., 2011).

A battery of behavioral and cognitive tests were performed, including open-field, elevated plus maze, Porsolt’s forced swim, and Morris’ water maze, to evaluate anxietyand depression-like behaviors, and learning and memory. Results showed that chia supplementation was ineffective against Alzheimer’s-related anxiety, whereas depression-like behaviors were attenuated with both pretreatment and treatment. There was no improvement in learning and memory with chia treatment

INTRODUCTION
In rodents, maternal stress during pregnancy can cause psychopathologies in the offspring, such as anxiety and depressive-like behaviors, as well as cognitive deficits (Weinstock, 2017). Also, alterations in development and maturation of brain structures, such as the hippocampus, have been reported (Fujioka et al., 2006). The dorsal hippocampus is involved in spatial learning and memory processes in rats and primates (Bannerman et al., 2004; Tanti and Belzung, 2013; Grigoryan and

interactions (Yun et al., 2018). Sarkar et al. (2015) discovered that the oestrogen-induced amelioration of Aβ-induced damage in mitochondria is regulated by mitochondrial signalling pathways and oxidative phosphorylation involving estrogen receptor (ER) β and A kinase anchoring protein (AKAP). Further research suggested that oestrogen may protect against learning and memory impairment through the regulation of Aβ deposition and neuroinflammation by inhibiting nuclear factor kappa B (NF-κB) activity in

DMNG-3 (3β-Methyl-[2-(4-nitrophenoxy)ethyl]-amino]con-5-enine), is a new and the potentially most potent acetylcholinesterase inhibitor recently obtained from conessine by N-demethylation and nucleophilic substitution reaction. In the present study, a step‑down passive avoidance test was used to investigate whether DMNG-3 could modulate impairment of learning and memory induced by scopolamine, and a high performance liquid chromatography (HPLC) method for the determination of DMNG-3 in

Previous studies on the positive effects of Ang IV on learning and memory have led to the question of whether it might play a curative role in cognitive disorders that develop in DM. Therefore, in this study, we aimed to investigate the effect of Ang IV

Muscarinic acetylcholine receptors (mAChR) are known to be related to learning and memory processes. Inactivation of mAChR by cholinergic antagonists have been shown to produce amnesia in a variety of behavioral tasks. In this study, we investigated the role of M1 and M2 AChR on passive avoidance learning and plasticity of synapses formed by Schaffer collaterals in freely moving rats. Experiments were performed using Wistar male rats. Seven days before testing, a recording electrode was lowered

Prolonged or repeated seizures have been shown to cause spontaneous recurrent seizures, increased anxiety-related behavior, locomotor hyperactivity, impaired functions of learning and memory, and neuronal damage in the hippocampus and other brain regions in animals. Mice and rats treated with antimuscarinic drugs after fasting for two days or less develop convulsions after being allowed to eat ad libitum. To address whether such behavioral and neuroanatomic changes occur following these
