Learning & Memory

Persistent up-regulation of polyribosomes at synapses during long-term memory, reconsolidation, and extinction of associative memory [RESEARCH]

Local protein synthesis at synapses can provide a rapid supply of proteins to support synaptic changes during consolidation of new memories, but its role in the maintenance or updating of established memories is unknown. Consolidation requires new pro…

Learning & Memory

Attentional capture by signals of reward persists following outcome devaluation [RESEARCH]

Attention, the mechanism that prioritizes stimuli in the environment for further processing, plays an important role in behavioral choice. In the present study, we investigated the automatic orienting of attention to cues that signal reward. Such atte…

Darting across space and time: parametric modulators of sex-biased conditioned fear responses [RESEARCH]

Pavlovian fear conditioning is a widely used behavioral paradigm for studying associative learning in rodents. Despite early recognition that subjects may engage in a variety of both conditioned and unconditioned responses, the last several decades ha…

Learning & Memory

Subsampling of cues in associative learning [RESEARCH]

Theories of learning distinguish between elemental and configural stimulus processing depending on whether stimuli are processed independently or as whole configurations. Evidence for elemental processing comes from findings of summation in animals wh…

Decision uncertainty during hypothesis testing enhances memory accuracy for incidental information [RESEARCH]

Humans actively seek information to reduce uncertainty, providing insight on how our decisions causally affect the world. While we know that episodic memories can help support future goal-oriented behaviors, little is known about how hypothesis testin…
