Barker, Jacqueline M.; Bryant, Kathleen G.; Chandler, L. Judson – Learning & Memory, 2019
The loss of behavioral flexibility is common across a number of neuropsychiatric illnesses. This may be in part due to the loss of the ability to detect or use changes in action-outcome contingencies to guide behavior. There is growing evidence that the ventral hippocampus plays a critical role in the regulation of flexible behavior and…

Mancini, Nino; Hranova, Sia; Weber, Julia; Weiglein, Alice; Schleyer, Michael; Weber, Denise; Thum, Andreas S.; Gerber, Bertram – Learning & Memory, 2019
Adjusting behavior to changed environmental contingencies is critical for survival, and reversal learning provides an experimental handle on such cognitive flexibility. Here, we investigate reversal learning in larval "Drosophila." Using odor-taste associations, we establish olfactory reversal learning in the appetitive and the aversive…

Piantadosi, Patrick T.; Lieberman, Abby G.; Pickens, Charles L.; Bergstrom, Hadley C.; Holmes, Andrew – Learning & Memory, 2019
Cognitive flexibility refers to various processes which enable behaviors to be modified on the basis of a change in the contingencies between stimuli or responses and their associated outcomes. Reversal learning is a form of cognitive flexibility which measures the ability to adjust responding based on a switch in the stimulus--outcome…

Exton-McGuinness, Marc T. J.; Patton, Rosemary C.; Sacco, Lawrence B.; Lee, Jonathan L. C. – Learning & Memory, 2014
Once consolidated, memories are dynamic entities that go through phases of instability in order to be updated with new information, via a process of reconsolidation. The phenomenon of reconsolidation has been demonstrated in a wide variety of experimental paradigms. However, the memories underpinning instrumental behaviors are currently not…

Weidemann, Gabrielle; Best, Erin; Lee, Jessica C; Lovibond, Peter F. – Learning & Memory, 2013
Single-cue delay eyeblink conditioning is presented as a prototypical example of automatic, nonsymbolic learning that is carried out by subcortical circuits. However, it has been difficult to assess the role of cognition in single-cue conditioning because participants become aware of the simple stimulus contingency so quickly. In this experiment…

Hupbach, Almut; Gomez, Rebecca; Hardt, Oliver; Nadel, Lynn – Learning & Memory, 2007
Recent demonstrations of "reconsolidation" suggest that memories can be modified when they are reactivated. Reconsolidation has been observed in human procedural memory and in implicit memory in infants. This study asks whether episodic memory undergoes reconsolidation. College students learned a list of objects on Day 1. On Day 2, they received a…

van Duuren, Esther; Nieto Escamez, Francisco A.; Joosten, Ruud N. J. M. A.; Visser, Rein; Mulder, Antonius B.; Pennartz, Cyriel M. A. – Learning & Memory, 2007
The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory…

Mehren, Jennifer E.; Griffith, Leslie C. – Learning & Memory, 2006
In "Drosophila," calcium/calmodulin-dependent protein kinase II (CaMKII) activity is crucial in associative courtship conditioning for both memory formation and suppression of courtship during training with a mated female. We have previously shown that increasing levels of constitutively active CaMKII, but not calcium-dependent CaMKII, in a subset…

Harrison, Fiona E.; Reiserer, Randall S.; Tomarken, Andrew J.; McDonald, Michael P. – Learning & Memory, 2006
The Barnes maze is a spatial memory task that requires subjects to learn the position of a hole that can be used to escape the brightly lit, open surface of the maze. Two experiments assessed the relative importance of spatial (extra-maze) versus proximal visible cues in solving the maze. In Experiment 1, four groups of mice were trained either…
