Talmi, Deborah; Kavaliauskaite, Deimante; Daw, Nathaniel D. – Learning & Memory, 2021
When people encounter items that they believe will help them gain reward, they later remember them better than others. A recent model of emotional memory, the emotional context maintenance and retrieval model (eCMR), predicts that these effects would be stronger when stimuli that predict high and low reward can compete with each other during both…

Levenson, Jonathan M.; Sweatt, J. David; Chwang, Wilson B.; O'Riordan, Kenneth J. – Learning & Memory, 2006
Long-term memory formation is regulated by many distinct molecular mechanisms that control gene expression. An emerging model for effecting a stable, coordinated pattern of gene transcription involves epigenetic tagging through modifications of histones or DNA. In this study, we investigated the regulation of histone phosphorylation in the…

Giurfa, Martin; Malun, Dagmar – Learning & Memory, 2004
The present work introduces a form of associative mechanosensory conditioning of the proboscis extension reflex (PER) in honeybees. In our paradigm, harnessed honeybees learn the elemental association between mechanosensory, antennal stimulation and a reward of sucrose solution delivered to the proboscis. Thereafter, bees extend their proboscis to…
