Manga, Annamária; Madurka, Petra; Vakli, Pál; Kirwan, C. Brock; Vidnyánszky, Zoltán – Learning & Memory, 2021
Binding visual features into coherent object representations is essential both in short- and long-term memory. However, the relationship between feature binding processes at different memory delays remains unexplored. Here, we addressed this question by using the Mnemonic Similarity Task and a delayed-estimation working memory task on a large…

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…

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…

Scott, Gavin A.; Liu, Max C.; Tahir, Nimra B.; Zabder, Nadine K.; Song, Yuanyi; Greba, Quentin; Howland, John G. – Learning & Memory, 2020
Working memory (WM), the capacity for short-term storage of small quantities of information for immediate use, is thought to depend on activity within the prefrontal cortex. Recent evidence indicates that the prefrontal neuronal activity supporting WM is driven by thalamocortical connections arising in mediodorsal thalamus (mdThal). However, the…

Davies, Don A.; Hurtubise, Jessica L.; Greba, Quentin; Howland, John G. – Learning & Memory, 2017
The trial-unique, delayed nonmatching-to-location (TUNL) task is a recently developed behavioral task that measures spatial working memory and a form of pattern separation in touchscreen-equipped operant conditioning chambers. Limited information exists regarding the neurotransmitters and neural substrates involved in the task. The present…

Fraize, Nicolas; Hamieh, Al Mahdy; Joseph, Mickael Antoine; Touret, Monique; Parmentier, Regis; Salin, Paul Antoine; Malleret, Gael – Learning & Memory, 2017
Phosphorylation of CaMKII and AMPA receptor GluA1 subunit has been shown to play a major role in hippocampal-dependent long-term/reference memory (RM) and in the expression of long-term synaptic potentiation (LTP). In contrast, it has been proposed that dephosphorylation of these proteins could be involved in the opposite phenomenon of hippocampal…

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…

Bolton, Sorcha; Robinson, Oliver J. – Learning & Memory, 2017
Anxiety disorders are the most common mental health disorders, and daily transient feelings of anxiety (or "stress") are ubiquitous. However, the precise impact of both transient and pathological anxiety on higher-order cognitive functions, including short- and long-term memory, is poorly understood. A clearer understanding of the…

Hales, Jena B.; Broadbent, Nicola J.; Velu, Priya D.; Squire, Larry R.; Clark, Robert E. – Learning & Memory, 2015
Structures in the medial temporal lobe, including the hippocampus and perirhinal cortex, are known to be essential for the formation of long-term memory. Recent animal and human studies have investigated whether perirhinal cortex might also be important for visual perception. In our study, using a simultaneous oddity discrimination task, rats with…

Alteba, Shirley; Korem, Nachshon; Akirav, Irit – Learning & Memory, 2016
Early life stress (ES) significantly increases predisposition to psychopathologies. Cannabinoids may cause cognitive deficits and exacerbate the effects of ES. Nevertheless, the endocannabinoid system has been suggested as a therapeutic target for the treatment of stress- and anxiety-related disorders. Here we examined whether cannabinoids…

Kahn, Julia B.; Ward, Ryan D.; Kahn, Lora W.; Rudy, Nicole M.; Kandel, Eric R.; Balsam, Peter D.; Simpson, Eleanor H. – Learning & Memory, 2012
Working memory and attention are complex cognitive functions that are disrupted in several neuropsychiatric disorders. Mouse models of such human diseases are commonly subjected to maze-based tests that can neither distinguish between these cognitive functions nor isolate specific aspects of either function. Here, we have adapted a simple visual…

Sannino, Sara; Russo, Fabio; Torromino, Giulia; Pendolino, Valentina; Calabresi, Paolo; De Leonibus, Elvira – Learning & Memory, 2012
The dorsal hippocampus is crucial for mammalian spatial memory, but its exact role in item memory is still hotly debated. Recent evidence in humans suggested that the hippocampus might be selectively involved in item short-term memory to deal with an increasing memory load. In this study, we sought to test this hypothesis. To this aim we developed…

Gupta, Kishan; Keller, Lauren A.; Hasselmo, Michael E. – Learning & Memory, 2012
Intrinsic persistent spiking mechanisms in medial entorhinal cortex (mEC) neurons may play a role in active maintenance of working memory. However, electrophysiological studies of rat mEC units have primarily focused on spatial modulation. We sought evidence of differential spike rates in the mEC in rats trained on a T-maze, cued spatial delayed…

Goonawardena, Anushka V.; Robinson, Lianne; Hampson, Robert E.; Riedel, Gernot – Learning & Memory, 2010
It is now well established that cannabinoid agonists such as [delta][superscript 9]-tetrahydrocannabinol (THC), anandamide, and WIN 55,212-2 (WIN-2) produce potent and specific deficits in working memory (WM)/short-term memory (STM) tasks in rodents. Although mediated through activation of CB1 receptors located in memory-related brain regions such…
