Ilse, Arne; Prameswari, Virginia; Kahl, Evelyn; Fendt, Markus – Learning & Memory, 2019
Trait anxiety is considered to be a risk factor for anxiety disorders. The aim of the present study was to investigate how trait anxiety affects associative learning during and after an aversive event in laboratory rats. For this, rats were first submitted to a light-dark box test, followed by relief, safety, and fear learning. Our data…

Wong, Edwin W.; Glasgow, Stephen D.; Trigiani, Lianne J.; Chitsaz, Daryan; Rymar, Vladimir; Sadikot, Abbas; Ruthazer, Edward S.; Hamel, Edith; Kennedy, Timothy E. – Learning & Memory, 2019
Netrin-1 was initially characterized as an axon guidance molecule that is essential for normal embryonic neural development; however, many types of neurons continue to express netrin-1 in the postnatal and adult mammalian brain. Netrin-1 and the netrin receptor DCC are both enriched at synapses. In the adult hippocampus, activity-dependent…

Colon, Lorianna; Odynocki, Natalie; Santarelli, Anthony; Poulos, Andrew M. – Learning & Memory, 2018
Development and sex differentiation impart an organizational influence on the neuroanatomy and behavior of mammalian species. Prior studies suggest that brain regions associated with fear motivated defensive behavior undergo a protracted and sex-dependent development. Outside of adult animals, evidence for developmental sex differences in…

Nelson, James Byron; Fabiano, Andrew M.; Lamoureux, Jeffrey A. – Learning & Memory, 2018
Two experiments assessed the effects of extinguishing a conditioned cue on subsequent context conditioning. Each experiment used a different video-game method where sensors predicted attacking spaceships and participants responded to the sensor in a way that prepared them for the upcoming attack. In Experiment 1 extinction of a cue which signaled…

König, Christian; Khalili, Afshin; Ganesan, Mathangi; Nishu, Amrita P.; Garza, Alejandra P.; Niewalda, Thomas; Gerber, Bertram; Aso, Yoshinori; Yarali, Ayse – Learning & Memory, 2018
Painful events establish opponent memories: cues that precede pain are remembered negatively, whereas cues that follow pain, thus coinciding with relief are recalled positively. How do individual reinforcement-signaling neurons contribute to this "timing-dependent valence-reversal?" We addressed this question using an optogenetic…

Antony, James W.; Paller, Ken A. – Learning & Memory, 2018
Repeatedly studying information is a good way to strengthen memory storage. Nevertheless, testing recall often produces superior long-term retention. Demonstrations of this testing effect, typically with verbal stimuli, have shown that repeated retrieval through testing reduces forgetting. Sleep also benefits memory storage, perhaps through…

Marshall, Andrew T.; Ostlund, Sean B. – Learning & Memory, 2018
Drug-paired cues acquire powerful motivational properties, but only lead to active drug-seeking behavior if they are potent enough to overwhelm the cognitive control processes that serve to suppress such urges. Studies using the Pavlovian-to-instrumental transfer (PIT) task have shown that rats pretreated with cocaine or amphetamine exhibit…

Peters, Jamie; Scofield, Michael D.; Reichel, Carmela M. – Learning & Memory, 2018
Prolonged use of methamphetamine (meth) has been associated with episodic memory deficits in humans, and preclinical rat models of meth self-administration indicate the memory deficits are a consequence of meth use. Others have suggested that the meth-induced memory deficits may promote a cyclical pattern of drug use, abstinence, and relapse,…

Matell, Matthew S.; Della Valle, Rebecca B. – Learning & Memory, 2018
Presentation of a previously trained Pavlovian conditioned stimulus while an organism is engaged in operant responding can moderate the rate of responding, a phenomenon known as Pavlovian-to-instrumental transfer. Although it is well known that Pavlovian contingencies will generate conditioned behavior that is temporally organized with respect to…

Vogel, Susanne; Kluen, Lisa Marieke; Fernández, Guillén; Schwabe, Lars – Learning & Memory, 2018
Prior knowledge, represented as a mental schema, has critical impact on how we organize, interpret, and process incoming information. Recent findings indicate that the use of an existing schema is coordinated by the medial prefrontal cortex (mPFC), communicating with parietal areas. The hippocampus, however, is crucial for encoding…

Smedley, Elizabeth B.; Smith, Kyle S. – Learning & Memory, 2018
Sign-tracking is a form of autoshaping where animals develop conditioned responding directed toward stimuli predictive of an outcome even though the outcome is not contingent on the animal's behavior. Sign-tracking behaviors are thought to arise out of the attribution of incentive salience (i.e., motivational value) to reward-predictive cues. It…

Baggett, Vincent; Mishra, Aditi; Kehrer, Abigail L.; Robinson, Abbey O.; Shaw, Paul; Zars, Troy – Learning & Memory, 2018
Animals in a natural environment confront many sensory cues. Some of these cues bias behavioral decisions independent of experience, and action selection can reveal a stimulus-response (S-R) connection. However, in a changing environment it would be a benefit for an animal to update behavioral action selection based on experience, and learning…

Sinclair, Alyssa H.; Barense, Morgan D. – Learning & Memory, 2018
Through the process of "reconsolidation," reminders can temporarily destabilize memories and render them vulnerable to change. Recent rodent research has proposed that prediction error, or the element of surprise, is a key component of this process; yet, this hypothesis has never before been extended to complex episodic memories in…

Doncheck, Elizabeth M.; Hafenbreidel, Madalyn; Ruder, Sarah A.; Fitzgerald, Michael K.; Torres, Lilith; Mueller, Devin – Learning & Memory, 2018
In cocaine use disorder, relapse can be elicited by drug-associated cues despite long periods of abstinence. The persistence of drug-associated cues in eliciting drug seeking suggests enduring changes in structural and functional plasticity, which may be mediated by basic fibroblast growth factor (bFGF, FGF2). Stimulant drug use increases bFGF…

Cohen, Justine E.; Ross, Robert S.; Stern, Chantal E. – Learning & Memory, 2018
Previous research has demonstrated that areas in the medial temporal lobe and prefrontal cortex (PFC) show increased activation during retrieval of overlapping sequences. In this study, we designed a task in which degree of overlap varied between conditions in order to parse out the contributions of hippocampal and prefrontal subregions as overlap…
