Sadeh, Talya; Shohamy, Daphna; Levy, Dana Rubi; Reggev, Niv; Maril, Anat – Journal of Cognitive Neuroscience, 2011
The hippocampus and the striatum are thought to play distinct roles in learning and memory, each supporting an independent memory system. A fundamental question is whether, and how, these systems interact to jointly contribute to learning and memory. In particular, it remains unknown whether the striatum contributes selectively to implicit,…

Ashby, F. Gregory; Crossley, Matthew J. – Journal of Cognitive Neuroscience, 2011
An essential component of skill acquisition is learning the environmental conditions in which that skill is relevant. This article proposes and tests a neurobiologically detailed theory of how such learning is mediated. The theory assumes that a key component of this learning is provided by the cholinergic interneurons in the striatum known as…

Cowell, Rosemary A.; Bussey, Timothy J.; Saksida, Lisa M. – Journal of Cognitive Neuroscience, 2010
We examined the organization and function of the ventral object processing pathway. The prevailing theoretical approach in this field holds that the ventral object processing stream has a modular organization, in which visual perception is carried out in posterior regions and visual memory is carried out, independently, in the anterior temporal…

Alexander, Michael P.; Stuss, Donald; Gillingham, Susan – Journal of Cognitive Neuroscience, 2009
Background: List-learning tasks are frequently used to provide measures of "executive functions" that are believed necessary for successful memory performance. Small sample sizes, confounding anomia, and incomplete representation of all frontal regions have prevented consistent demonstration of distinct regional frontal effects on this task.…

Shohamy, Daphna; Myers, Catherine E.; Hopkins, Ramona O.; Sage, Jake; Gluck, Mark A. – Journal of Cognitive Neuroscience, 2009
The hippocampus and the basal ganglia are thought to play fundamental and distinct roles in learning and memory, supporting two dissociable memory systems. Interestingly, however, the hippocampus and the basal ganglia have each, separately, been implicated as necessary for reversal learning--the ability to adaptively change a response when…
