Abstract
Object recognition memory refers to a basic memory mechanism to identify and recall various features of objects. This memory has been investigated by numerous studies in human, primates and rodents to elucidate the neuropsychological underpinnings in mammalian memory, as well as provide the diagnosis of dementia in some neurological diseases, such as Alzheimer's disease and Parkinson's disease. Since Alzheimer's disease at the early stage is reported to be accompanied with cholinergic cell loss and impairment in recognition memory, the central cholinergic system has been studied to investigate the neural mechanism underlying recognition memory. Previous studies have suggested an important role of cholinergic neurons in the acquisition of some variants of object recognition memory in rodents. Cholinergic neurons in the medial septum and ventral diagonal band of Broca that project mainly to the hippocampus and parahippocampal area are related to recognition memory for object location. Cholinergic projections from the nucleus basalis magnocellularis innervating the entire cortex are associated with recognition memory for object identification. Especially, the brain regions that receive cholinergic projections, such as the perirhinal cortex and prefrontal cortex, are involved in recognition memory for object-in-place memory and object recency. In addition, experimental studies using rodent models for Alzheimer's disease have reported that neurodegeneration within the central cholinergic system causes a deficit in object recognition memory. Elucidating how various types of object recognition memory are regulated by distinct cholinergic cell groups is necessary to clarify the neuronal mechanism for recognition memory and the development of therapeutic treatments for dementia.

Front Mol Neurosci 2022; 15:912146. [PMID: 36061362 PMCID: PMC9428565 DOI: 10.3389/fnmol.2022.912146] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 06/21/2022] [Indexed: 11/17/2022] Open
Abstract
Behavioral neuroscience tests such as the Light/Dark Test, the Open Field Test, the Elevated Plus Maze Test, and the Three Chamber Social Interaction Test have become both essential and widely used behavioral tests for transgenic and pre-clinical models for drug screening and testing. However, as fast as the field has evolved and the contemporaneous involvement of technology, little assessment of the literature has been done to ensure that these behavioral neuroscience tests that are crucial to pre-clinical testing have well-controlled ethological motivation by the use of lighting (i.e., Lux). In the present review paper, N = 420 manuscripts were examined from 2015 to 2019 as a sample set (i.e., n = ~20–22 publications per year) and it was found that only a meager n = 50 publications (i.e., 11.9% of the publications sampled) met the criteria for proper anxiogenic and anxiolytic Lux reported. These findings illustrate a serious concern that behavioral neuroscience papers are not being vetted properly at the journal review level and are being released into the literature and public domain making it difficult to assess the quality of the science being reported. This creates a real need for standardizing the use of Lux in all publications on behavioral neuroscience techniques within the field to ensure that contributions are meaningful, avoid unnecessary duplication, and ultimately would serve to create a more efficient process within the pre-clinical screening/testing for drugs that serve as anxiolytic compounds that would prove more useful than what prior decades of work have produced. It is suggested that improving the standardization of the use and reporting of Lux in behavioral neuroscience tests and the standardization of peer-review processes overseeing the proper documentation of these methodological approaches in manuscripts could serve to advance pre-clinical testing for effective anxiolytic drugs. This report serves to highlight this concern and proposes strategies to proactively remedy them as the field moves forward for decades to come.

Abstract
Novelty seems to reduce the persistence of aversive memories and to modulate frustration responses, yet much less is known on how this treatment affects memories lacking hedonic or emotional content. The present study analyzed how a 5-min exposure to a novel open field modulated the expression of a spatial recognition memory. Experiment 1 indicated that male Wistar rats trained in a T-maze in which one goal arm is blocked exhibit, when tested 2 h later, preference for the novel arm. This recognition memory was impaired by the muscarinic cholinergic antagonist scopolamine. Postraining, but not pretraining, novelty exposure rescued the cognitive impairment induced by scopolamine (Experiment 2 and 3). Pretraining open field exposure alleviated the lack of memory expression, induced by imposing a 6 h delay between training and testing (Experiment 4). The study shows that a very brief exposure to novelty can improve expression of a spatial, recognition memory, a modulation that - in the case of the pretraining novelty exposure -- emerges even in spite of cholinergic blockade. The present results are consistent with research suggesting that novelty exposure can be an effective, non-pharmacological, treatment to modulate memory expression.

Abstract
The detection and processing of novelty play a critical role in memory formation. The effect of novelty intervention in memory has been demonstrated with rodents in several lines of research; however, it has not been explored as extensively in humans. In this research, we evaluated the effect of novelty exposure on two types of emotional memory: visual (Study 1) and verbal (Study 2). Eighty healthy volunteers participated in both studies. First, all participants watched a video (session 1); seven days later (session 2), participants in the control group watched the same video and those in the experimental condition were exposed to a novel one. Immediately after exposure, all participants looked at 36 pictures (or listened to 36 words). Soon afterward, a two-task test was administered to evaluate memory (immediate free recall and recognition). A week later (session 3), the two-task test was run again (deferred free recall and recognition). Regarding emotional memory processing, the emotional information was more activating and better remembered than the neutral one, for both visual and verbal information. Regarding the novelty effect, the participants exposed to the novel video had better recall than the control on the deferred measures. Thus, our results provide evidence of the effect of novelty exposure on two different types of emotional memory, with great potentialities in clinical and educational settings.
