Data from: Cortical reactivation of spatial and non-spatial features coordinates with hippocampus to form a memory dialogue
<p>Episodic memories comprise diverse attributes of experience distributed across neocortical areas. The hippocampus is integral to rapidly binding these diffuse representations, as they occur, to be later reinstated. However, the nature of the information exchanged during this hippocampal-cortical dialogue remains poorly understood. A recent study has shown that the secondary motor cortex carries two types of representations: place cell-like activity, which were impaired by hippocampal lesions, and responses tied to visuo-tactile cues, which became more pronounced following hippocampal lesions. Using two-photon Ca<sup>2+</sup> imaging to record neuronal activities in the secondary motor cortex of male Thy1-GCaMP6s mice, we assessed the cortical retrieval of spatial and non-spatial attributes from previous explorations in a virtual environment. We show that, following navigation, spontaneous resting state reactivations convey varying degrees of spatial (trajectory sequences) and non-spatial (visuo-tactile attributes) information, while reactivations of non-spatial attributes tend to precede reactivations of spatial representations surrounding hippocampal sharp-wave ripples.</p>

Data from: Prey encounters and spatial memory influence use of foraging patches in a marine central place forager
<p class="MsoNormal">Given the patchiness and long-term predictability of marine resources, memory of high-quality foraging grounds is expected to provide fitness advantages for central place foragers. However, it remains challenging to characterise how marine predators integrate memory with recent prey encounters to adjust fine-scale movement and use of foraging patches. Here, we used two months of movement data from harbour seals (<em>Phoca vitulina</em>) to quantify the repeatability in foraging patches as a proxy for memory. We then integrated these data into analyses of fine-scale movement and underwater behaviour to test how both spatial memory and prey encounter rates influenced the seals' Area Restricted Search (ARS) behaviour. Specifically, we used one month's GPS data from 29 individuals to build spatial memory maps of searched areas, and archived accelerometry data from a subset of five individuals to detect prey catch attempts, a proxy for prey encounters. Individuals were highly consistent in the areas they visited over two consecutive months. Hidden Markov Models showed that both spatial memory and prey encounters increased the probability of seals initiating ARS. These results provide evidence that predators use memory to adjust their fine scale movement and this ability should be accounted for in movement models.</p>
Dataset for the study "Changes in audio-spatial working memory abilities during childhood: The role of spatial and phonological development"
<p>Working memory is a cognitive system devoted to storage and retrieval processing of information.<br> Numerous studies on the development of working memory have investigated the<br> processing of visuo-spatial and verbal non-spatialized information; however, little is known<br> regarding the refinement of acoustic spatial and memory abilities across development.<br> Here, we hypothesize that audio-spatial memory skills improve over development, due to<br> strengthening spatial and cognitive skills such as semantic elaboration. We asked children<br> aged 6 to 11 years old (n = 55) to pair spatialized animal calls with the corresponding animal<br> spoken name. Spatialized sounds were emitted from an audio-haptic device, haptically<br> explored by children with the dominant hand’s index finger. Children younger than 8<br> anchored their exploration strategy on previously discovered sounds instead of holding this<br> information in working memory and performed worse than older peers when asked to pair<br> the spoken word with the corresponding animal call. In line with our hypothesis, these findings<br> demonstrate that age-related improvements in spatial exploration and verbal coding<br> memorization strategies affect how children learn and memorize items belonging to a complex<br> acoustic spatial layout. Similar to vision, audio-spatial memory abilities strongly depend<br> on cognitive development in early years of life.</p> <p>Data in the file are divided into six sheets based on the age of the participants and the experimental condition, either call-call or call-name. Each sheet contains six columns: Participant ID, age and gender are the first three. The last three columns instead refer to the test parameters: the number of attempts, the audio-anchor and the score. In details, the number of attempts indicates the number of trials needed to pair the sounds. The audio-anchor provides a measurement of the exploration strategy. It accounts for how many consecutive attempts the child begins by touching the same speaker while the score takes into account the frequency of touches on the same speakers: the more the participant returns on the same stimulus location, the lower the score.</p>

Data from: Social context alters spatial memory performance in free-living male prairie voles
<p>Spatial memory is crucial for mating success because it enables males to locate potential mates and potential competitors in space. Intraspecific competition and its varying intensity under certain conditions are potentially important for shaping spatial memory. For example, spatial memory could enable males to know where competitors are (contest competition), it could help males find mating partners (scramble competition), or both. We manipulated the intensity of intraspecific competition in two distinct contexts by altering the operational sex ratio of prairie voles (<i>Microtus ochrogaster</i>) living in outdoor enclosures by creating male- and female-biased sex ratios. After living freely under these contexts for four weeks, we compared males' performance in a laboratory spatial memory test. Males in the male-biased context demonstrated better spatial memory performance than males in the female-biased context. Notably, these data show that in spite of experiencing equally complex<i>spatial</i>contexts (i.e., natural outdoor enclosures), it was the <i>social </i>context that influenced spatial cognition, and it did so in a manner consistent with the hypothesis that spatial memory is particularly relevant for male-male interactions. Attached are the supporting data for this project.</p>
Data from: Female cowbirds have more accurate spatial memory than males
Brown-headed cowbirds (Molothrus ater) are obligate brood parasites. Only females search for host nests and they find host nests one or more days before placing eggs in them. Past work has shown that females have a larger hippocampus than males, but sex differences in spatial cognition have not been extensively investigated. We tested cowbirds for sex and seasonal differences in spatial memory on a foraging task with an ecologically relevant retention interval. Birds were trained to find one rewarded location among 25 after 24 h. Females made significantly fewer errors than males and took more direct paths to the rewarded location than males. Females and males showed similar search times, indicating there was no sex difference in motivation. This sex difference in spatial cognition is the reverse of that observed in some polygynous mammals and is consistent with the hypothesis that spatial cognition is adaptively specialized in this brood-parasitic species.
Data from: Spatial memory shapes migration and its benefits: evidence from a large herbivore
From fine-scale foraging to broad-scale migration, animal movement is shaped by the distribution of resources. There is mounting evidence, however, that learning and memory also guide movement. Although migratory mammals commonly track resource waves, how resource tracking and memory guide long-distance migration has not been reconciled. We examined these hypotheses using movement data from four populations of migratory mule deer (n=91). Spatial memory had an extraordinary influence on migration, affecting movement 2–28 times more strongly than tracking spring green-up or autumn snow depth. Importantly, with only an ability to track resources, simulated deer were unable to recreate empirical migratory routes. In contrast, simulated deer with memory of empirical routes, used those routes and obtained higher foraging benefits. For migratory terrestrial mammals, spatial memory provides knowledge of where seasonal ranges and migratory routes exist, while resource tracking determines when to beneficially move within those areas.
Data from: Incorporating animal spatial memory in step selection functions
Memory is among the most important and neglected forces that shapes animal movement patterns. Research on the movement-memory interface is crucial to understand how animals use spatial learning to navigate across space because memory-biased navigation is directly linked to animals' space use and home range behaviour; however, because memory cannot be measured directly, it is difficult to account for. Here, we incorporated spatial memory into Step Selection Functions (SSF) to understand how resource selection and spatial memory affect space use of feral hogs (Sus scrofa). We used Biased Random Bridge kernel estimates linked to residence time as a surrogate for memory and tested four conceptually different dynamic maps of spatial memory. We applied this memory-based SSF to a data set of hog relocations to evaluate the importance of land cover type, time of day, and spatial memory on the animals' space use. Our approach has shown how the incorporation of spatial memory into animal movement models can improve estimates of habitat selection. Memory-based SSF provided a feasible way to gain insight into how animals use spatial learning to guide their movement decisions. We found that while hogs selected forested areas and water bodies and avoided grasslands during the day (primarily at noon), they had a strong tendency to select previously visited areas, mainly those held in recent memory. Beyond actively updating their memory with recent experiences, hogs were able to discriminate among spatial memories encoded at different circadian phases of their activity. Even though hogs are thought to have long memory retention, they likely relied on recent experiences because the local food resources are quickly depleted and slowly renewed, yielding an uncertain spatial distribution of resources.
