They were given a time limit of 60 seconds to find the escape platform after which they were escorted onto the platform by a test participant. During the daily testing sessions, mouse tests were conducted in groups of 4 mice. Each mouse was kept in cages that were separate and filled with an encasement of paper towels. After the day of the acquisition of training and memory testing, the mice were tested using an individual 60-second probe trial without an escape platform. Mice then went through a single day of re-training in order to limit the possibility of extinction in the probe trial. In the course of re-training, the escape system is moved back to the same site used during the acquisition phase. After acquisition re-training, reverse learning was evaluated over three days (R1-R3) using the escape platform relocated to the opposite end of the maze.

This paper presents an open-source analysis software, “Pathfinder”, for testing the standard tests of memory and spatial learning and an evaluation of the patterns and strategies used by swimmers that alter in a systematic fashion throughout the various phases of learning. The paper provides a brief historical account of the discovery and use of the Morris water task suggesting that the earlier work lacked sophistication in their analysis of this complex cognitive/navigational behavior, relying mostly on latency and path length. The paper will be followed by a brief description of the software, which includes that it is able to interface with popular systems for tracking and analysis of behavioral behavior and is free to download. These two capabilities will ensure that it is used in a variety of ways by scientists with different perspectives and opinions.

In the opinion of Gonzalez and coworkers18, The deficits observed in these test subjects were due to brain manipulations that weakened the support of memory and learning which led to the subjects using the platform less frequently during the training process as compared to a normal subject. We examined these claims and found that normal rats who received only a small amount of reinforcement for the spatial aspect of the water test showed reduced escape times. But, using a combination of zones and time bins and zone analysis, we found that the rats who received partial reinforcement were able to swim straight to the right position early in the test and, if they couldn’t find it, they swam towards the wall of the pool. The pool wall is also a source for reinforcement since the subject is removed by the participant at this point when the trial has ended.

Based on some of the experiments conducted using the MWT9 It appears in a way that is counterintuitive, that rats use the design of the testing apparatus and the direction of the test to find the exit location. The results showed clearly that the majority of rats relied on a directional representation instead of any representation of the connections between the cues within the room for testing. This is crucial to know because of various reasons, but it is especially relevant to the current review since moving to a different room does not lead to a random search of the pool as is commonly believed. Instead, at the beginning of training, they will be swimming in a direction that is probably not the correct one. To allow for a visual representation of the search’s performance We used Pathfinder to create heatmaps of spatial movement at times of testing that varied in the patterns of spatial search. When averaged across all trials and across genders mice swim near to the pool’s wall on day one of initial acquisition.

There are other, free programs that were developed by researchers. It is certainly interesting to make a comparison. It would certainly be beneficial to confirm it with a well-established model of hippocampal dysfunction that could be a result of an injury. It could detect the deficits which have been reported in the past, as rodents with hippocampal lesioning tend to be thigmotactic, and less spatially precise and this is something that Pathfinder clearly demonstrates at the beginning of training in our research. We have validated it with neurogenesis-deficient rats, where these rats displayed a strategy phenotype that was probably relatively subtle compared to hippocampal-lesioned animals. In order for this to be effective, it is essential for the user to comprehend the behavior of their subject and modify the parameters so that the individual’s strategies are observed. This will improve the detection of strategies’ effectiveness and sensitivity. However, users should remain careful when they interpret the results and assessing whether the parameters that have been fine-tuned detect significant variations or not.

Semi-focal Search (not-shown) which is a less sloppy focal search, is classified as 5th after indirect search. For example, in order for an experiment to be classified as Random Search, the path must be able to cover a certain percentage of the maze but not meet the criteria of strategies 1-7. In the examples in the diagram, the blue square is the starting point, while the green circle represents where the central portion of the lake is. The parameters used are the ones employed in the present study and can be altered according to changes in testing methods and maze geometry. The importance that the HVS tracking system in creating the MWT an important instrument for behavioral neuroscience and biomedical research shouldn’t be ignored. Two labs that contributed to the creation of this research and the understanding of the brain’s systems and mechanisms that were involved utilized to use the HVS tracking system, and later created their own program for data collection and analysis to use in their own labs.

We analyzed the navigation response strategies used by rats in every training trial by observing each swim and categorizing their behavior. We reproduced the findings of previous studies that showed mice suffering from ventral HPC lesions show impairments during the initial stages of training, but not later in the training. In addition, we discovered certain clear differences pertinent to the “Pathfinder” program. In our research, VHPC affected rats employed the general search strategy during the initial and middle stages of their training, whereas the rats that were sham changed to direct strategies for searching towards an escape system earlier. The switch towards direct strategies for search in rats that were controlled was more recent than that of the mice used in the Ruediger tests. As we’ve argued previously, these species and possibly strain variations are crucial to be aware of when you are using any of these types of automation analysis tools22.

A reverse probe test was completed to test memory regarding the location of an escape platform in a new. Then, a single day of training on the visible platform (Visible platform four trial) was completed. During this time, the platform for escape was relocated to a different location and then made visible through the use of a flag with stripes. It is important to note that in water maze studies, certain actions (e.g. the chaining process and thigmotaxis) are fairly well-defined. Contrarily, the different patterns of spatially-specific searching could be intuitive and quantifiable, but the degree to which they have a meaning and are a result of distinct neural processes isn’t as apparent. It is certainly true that search strategies can be quantifiable can open the way to future research into the nature of sophisticated navigation strategies. But, to a certain degree, the definitions of strategies are not precise which is why it’s the responsibility of the user to decide which actions are appropriate to their particular approach. Regarding your concerns, we didn’t know that commercial software programs include analysis of strategies.

Pathfinder also demonstrated the reverse transformation from procedural to spatial random strategies during the probe test. By analyzing reversal performance with respect to multiple goal locations, Pathfinder showed that mice redirect their spatial search from the previously-reinforced platform location to the new location. Mice used a variety of search strategies at any day, even when the performance of escape had slowed. Manual classification using static images of the swim path was inefficient and inconsistent The Pathfinder tool could therefore be an effective tool for qualitatively evaluating the strategies used by rodents in their water maze, as well as spatial navigation within other behavior models. The concept of spatial navigation has become a behavior that is influenced by objectives, experience, and sensory stimuli. The tasks of spatial navigation are frequently utilized to study memory, learning, and goal-directed behavior in both mammals and humans.

It is interesting to see if the authors would discuss ways in which they could use the “Pathfinder” system could be utilized to record these complicated swimming strategies in the various experiments discussed as well as how bin analysis could be integrated. It also raises some questions regarding the ways in which Pathfinder could be used to identify strategies that are related to competing goals. We tried to explain some scenarios where rodents must make a decision between cued and spatial goals, and a variety of spatial objectives. These papers are cited for readers’ reference and believe they offer an excellent illustration of how the maze could be utilized to study decision-making, conflicts between brain regions and strategies, and similar. The possibilities are endless and the final outcome depends on the imagination of the participants.

One of the most popular methods for test spatial memory includes an exercise called the Morris water maze. people learn the exact location of a platform, which allows them to escape the water pool. The majority of researchers describe learning as a result of the time it takes to escape, but this is not revealing much about fundamental navigational strategies. Recently, several studies have begun to categorize the strategies used to search for water to help clarify the exact functionalities of the spatial and mnemonic regions of various brain regions and to determine what aspects of spatial memory are affected in models of disease. Yet, despite their utility strategies analyses haven’t been widely used because of the lack of tools to automatize analyses. To address this issue, we created Pathfinder an open-source application that is used to analyze spatial navigation behavior. Through a large-scale study, we demonstrate that Pathfinder effectively identifies the evolution of highly specific spatial search strategies when female and male mice navigate the basic map of water in a spatial. It is easy to use, it can instantly determine the pool and platform geometry, creates heat maps, analyses navigation with regard to various destinations, and it is able to be upgraded to take into account the latest developments in spatial behavior analysis.

According to the authors they aren’t sure what the possible benefits of the analysis of swimming paths are made in”Pathfinder. “Pathfinder” system might be and they suggest potential research avenues that could prove fruitful. According to us, a research area that could be most beneficial is a re-evaluation of the memory and learning network that is focused around that of the HPC and the importance that each area plays in the various elements of navigation through the environment. Another subject of inquiry is to reexamine the roles of different neurotransmitters, including ascending modulator systems as well as the neurotransmitter system located in every sub-region. These research areas could be explored using traditional and “state of the art” methods, such as neurotoxic lesions inactivation methods, behavioral imaging, optogenetics and pharmacology, and so on.
