Radiske, Andressa; Gonzalez, Maria Carolina; Nôga, Diana A.; Rossato, Janine I.; Bevilaqua, Lia R. M.; Cammarota, Martín – Learning & Memory, 2021
Fear-motivated avoidance extinction memory is prone to hippocampal brain-derived neurotrophic factor (BDNF)-dependent reconsolidation upon recall. Here, we show that extinction memory recall activates mammalian target of rapamycin (mTOR) in dorsal CA1, and that post-recall inhibition of this kinase hinders avoidance extinction memory persistence…

Sato, Misato; Álvarez, Beatriz; Mizunami, Makoto – Learning & Memory, 2021
The effect of repetitive training on learned behavior has been an important subject in neuroscience. In instrumental conditioning in mammals, learned action early in training is often goal-driven and controlled by outcome expectancy, but as training progresses, it becomes more habitual and insensitive to outcome devaluation. Similarly, we recently…

Eckert, Michael J.; Iyer, Kartik; Euston, David R.; Tatsuno, Masami – Learning & Memory, 2021
Neocortical sleep spindles have been shown to occur more frequently following a memory task, suggesting that a method to increase spindle activity could improve memory processing. Stimulation of the neocortex can elicit a slow oscillation (SO) and a spindle, but the feasibility of this method to boost SO and spindles over time has not been tested.…

Sneddon, Elizabeth A.; Riddle, Collin A.; Schuh, Kristen M.; Quinn, Jennifer J.; Radke, Anna K. – Learning & Memory, 2021
Early life stress (ELS) experiences can cause changes in cognitive and affective functioning. This study examined the persistent effects of a single traumatic event in infancy on several adult behavioral outcomes in male and female C57BL/6J mice. Mice received 15 footshocks in infancy and were tested for stress-enhanced fear learning, extinction…

Kamada, Taisuke; Hata, Toshimichi – Learning & Memory, 2021
Dopamine plays a critical role in behavioral tasks requiring interval timing (time perception in a seconds-to-minutes range). Although some studies demonstrate the role of dopamine receptors as a controller of the speed of the internal clock, other studies demonstrate their role as a controller of motivation. Both D1 dopamine receptors (D1DRs) and…

Craig, Michael; Knowles, Christopher; Hill, Stephanie; Dewar, Michaela – Learning & Memory, 2021
Awake quiescence immediately after encoding is conducive to episodic memory consolidation. Retrieval can render episodic memories labile again, but reconsolidation can modify and restrengthen them. It remained unknown whether awake quiescence after retrieval supports episodic memory reconsolidation. We sought to examine this question via an…

Derouet, Joffrey; Droit-Volet, Sylvie; Doyère, Valérie – Learning & Memory, 2021
The present study evaluates the updating of long-term memory for duration. After learning a temporal discrimination associating one lever with a standard duration (4 sec) and another lever with both a shorter (1-sec) and a longer (16-sec) duration, rats underwent a single session for learning a new standard duration. The temporal generalization…

Murphy, Charlotte; Dehmelt, Vera; Yonelinas, Andrew P.; Ranganath, Charan; Gruber, Matthias J. – Learning & Memory, 2021
Curiosity states benefit memory for target information, but also incidental information presented during curiosity states. However, it is not known whether incidental curiosity-enhanced memory depends on when incidental information during curiosity states is encountered. Here, participants incidentally encoded unrelated face images at different…

Kodirov, Sodikdjon A.; Bonni, Kathrin; Wehrmeister, Michael; Lutz, Beat – Learning & Memory, 2021
The depolarization is also important for the short-term synaptic plasticity, known as depolarization-induced suppression of excitation (DSE). The two major types of neurons and their synapses in the lateral nucleus of amygdala (LA) are prone to plasticity. However, DSE in interneurons has not been reported in amygdala in general and in LA in…

Wong, J. Y. Hilary; Wan, Bo Angela; Bland, Tom; Montagnese, Marcella; McLachlan, Alex D.; O'Kane, Cahir J.; Zhang, Shuo Wei; Masuda-Nakagawa, Liria M. – Learning & Memory, 2021
Discrimination of sensory signals is essential for an organism to form and retrieve memories of relevance in a given behavioral context. Sensory representations are modified dynamically by changes in behavioral state, facilitating context-dependent selection of behavior, through signals carried by noradrenergic input in mammals, or octopamine (OA)…

Fry, Benjamin R.; Pence, Nathan T.; McLocklin, Andrew; Johnson, Alexander W. – Learning & Memory, 2021
The dopamine system has been implicated in decision-making particularly when associated with effortful behavior. We examined acute optogenetic stimulation of dopamine cells in the ventral tegmental area (VTA) as mice engaged in an effort-based decision-making task. Tyrosine hydroxylase-Cre mice were injected with Cre-dependent ChR2 or eYFP control…

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…

Taylor, William W.; Imhoff, Barry R.; Sathi, Zakia Sultana; Liu, Wei Y.; Garza, Kristie M.; Dias, Brian G. – Learning & Memory, 2021
Dysfunctions in memory recall lead to pathological fear; a hallmark of trauma-related disorders, like posttraumatic stress disorder (PTSD). Both, heightened recall of an association between a cue and trauma, as well as impoverished recall that a previously trauma-related cue is no longer a threat, result in a debilitating fear toward the cue.…

Homan, Philipp; Lau, H. Lee; Levy, Ifat; Raio, Candace M.; Bach, Dominik R.; Carmel, David; Schiller, Daniela – Learning & Memory, 2021
In an ever-changing environment, survival depends on learning which stimuli represent threat, and also on updating such associations when circumstances shift. It has been claimed that humans can acquire physiological responses to threat-associated stimuli even when they are unaware of them, but the role of awareness in updating threat…

Kikas, Katarina; Westbrook, R. Frederick; Holmes, Nathan M. – Learning & Memory, 2021
Four experiments examined the effects of a dangerous context and a systemic epinephrine injection on sensory preconditioning in rats. In each experiment, rats were exposed to presentations of a tone and light in stage 1, light-shock pairings in stage 2, and test presentations of the tone alone and light alone in stage 3. Presentations of the tone…
