Colettis, Natalia Claudia; Habif, Martín; Oberholzer, María Victoria; Filippin, Federico; Jerusalinsky, Diana Alicia – Learning & Memory, 2022
We observed differences in cognitive functions between middle-aged female and male Wistar rats. Both (like youngsters) discriminated new versus familiar objects, showing similar short- and long-term memory (STM and LTM, respectively). Only females show robust LTM for new location of an object. Both successfully form LTM of inhibitory avoidance,…

Brady, Ryan J.; Mickelberg, Jennifer M.; Hampton, Robert R. – Learning & Memory, 2021
The prefrontal cortex is larger than would be predicted by body size or visual cortex volume in great apes compared with monkeys. Because prefrontal cortex is critical for working memory, we hypothesized that recognition memory tests would engage working memory in orangutans more robustly than in rhesus monkeys. In contrast to working memory, the…

Skalaban, Lena J.; Cohen, Alexandra O.; Conley, May I.; Lin, Qi; Schwartz, Garrett N.; Ruiz-Huidobro, Nicholas A. M.; Cannonier, Tariq; Martinez, Steven A.; Casey, B. J. – Learning & Memory, 2022
Working memory and recognition memory develop across adolescence, but the relationship between them is not fully understood. We investigated associations between n-back task performance and subsequent recognition memory in a community sample (8-30 yr, n = 150) using tasks from the Adolescent Brain Cognitive Development Study (ABCD Study) to…

Gobin, Christina; Wu, Lizhen; Schwendt, Marek – Learning & Memory, 2020
The delayed match-to-sample task (DMS) is used to probe working memory (WM) across species. While the involvement of the PFC in this task has been established, limited information exists regarding the recruitment of broader circuitry, especially under the low- versus high-WM load. We sought to address this question by using a variable-delay…

Heuer, Sarah E.; Neuner, Sarah M.; Hadad, Niran; O'Connell, Kristen M. S.; Williams, Robert W.; Philip, Vivek M.; Gaiteri, Chris; Kaczorowski, Catherine C. – Learning & Memory, 2020
Individual differences in cognitive decline during normal aging and Alzheimer's disease (AD) are common, but the molecular mechanisms underlying these distinct outcomes are not fully understood. We utilized a combination of genetic, molecular, and behavioral data from a mouse population designed to model human variation in cognitive outcomes to…

Jordan, Jake T.; Tong, Yi; Pytte, Carolyn L. – Learning & Memory, 2022
Plasticity is a neural phenomenon in which experience induces long-lasting changes to neuronal circuits and is at the center of most neurobiological theories of learning and memory. However, too much plasticity is maladaptive and must be balanced with substrate stability. Area CA3 of the hippocampus provides such a balance via hemispheric…

Gemzik, Zachary M.; Donahue, Margaret M.; Griffin, Amy L. – Learning & Memory, 2021
Spatial working memory (SWM) is the ability to encode, maintain, and retrieve spatial information over a temporal gap, and relies on a network of structures including the medial septum (MS), which provides critical input to the hippocampus. Although the role of the MS in SWM is well-established, up until recently, we have been unable to use…

Solopchuk, Oleg; Alamia, Andrea; Olivier, Etienne; Zénon, Alexandre – Learning & Memory, 2016
Chunking, namely the grouping of sequence elements in clusters, is ubiquitous during sequence processing, but its impact on performance remains debated. Here, we found that participants who adopted a consistent chunking strategy during symbolic sequence learning showed a greater improvement of their performance and a larger decrease in cognitive…

Cheke, Lucy G. – Learning & Memory, 2016
Older adults exhibit disproportionate impairments in memory for item-associations. These impairments may stem from an inability to self-initiate deep encoding strategies. The present study investigates this using the "treasure-hunt task"; a what-where-when style episodic memory test that requires individuals to "hide" items…

Davies, Don A.; Greba, Quentin; Selk, Jantz C.; Catton, Jillian K.; Baillie, Landon D.; Mulligan, Sean J.; Howland, John G. – Learning & Memory, 2017
Working memory is involved in the maintenance and manipulation of information essential for complex cognition. While the neural substrates underlying working memory capacity have been studied in humans, considerably less is known about the circuitry mediating working memory capacity in rodents. Therefore, the present experiments tested the…

Patel, Nilam; Stoodley, Catherine; Pine, Daniel S.; Grillon, Christian; Ernst, Monique – Learning & Memory, 2017
This study examines the influence of trait anxiety on working memory (WM) in safety and threat. Interactions between experimentally induced anxiety and WM performance (on different cognitive loads) have been reported in healthy, nonanxious subjects. Differences in trait anxiety may moderate these interactions. Accordingly, these interactions may…

Leganes-Fonteneau, Mateo; Nikolaou, Kyriaki; Scott, Ryan; Duka, Theodora – Learning & Memory, 2019
Stimuli conditioned with a substance can generate drug-approach behaviors due to their acquired motivational properties. According to implicit theories of addiction, these stimuli can decrease cognitive control automatically. The present study (n = 49) examined whether reward-associated stimuli can interfere with cognitive processes in the absence…

Thielen, Jan-Willem; Takashima, Atsuko; Rutters, Femke; Tendolkar, Indira; Fernández, Guillén – Learning & Memory, 2015
To test the hypothesis that thalamic midline nuclei play a transient role in memory consolidation, we reanalyzed a prospective functional MRI study, contrasting recent and progressively more remote memory retrieval. We revealed a transient thalamic connectivity increase with the hippocampus, the medial prefrontal cortex (mPFC), and a…

Sanderson, David J.; Sprengel, Rolf; Seeburg, Peter H.; Bannerman, David M. – Learning & Memory, 2011
Deletion of the GluA1 AMPA receptor subunit selectively impairs short-term memory for spatial locations. We further investigated this deficit by examining memory for discrete nonspatial visual stimuli in an operant chamber. Unconditioned suppression of magazine responding to visual stimuli was measured in wild-type and GluA1 knockout mice.…

Jeneson, Annette; Squire, Larry R. – Learning & Memory, 2012
Early studies of memory-impaired patients with medial temporal lobe (MTL) damage led to the view that the hippocampus and related MTL structures are involved in the formation of long-term memory and that immediate memory and working memory are independent of these structures. This traditional idea has recently been revisited. Impaired performance…
