Research Interests: Cognitive Neuroscience, Memory, Cognitive Control, fMRI Methods

Overview: I am interested in how our perceptual experiences are transformed into memories and how we recreate and selectively recall these experiences. Research in my lab makes use of behavioral and neuroimaging methods (primarily fMRI) with an emphasis on applying machine learning algorithms and multivariate pattern analyses to neuroimaging data in order to understand how memories are represented and transformed in distributed patterns of brain activity.

Some of the specific topics my lab addresses include: What are the cognitive and neural mechanisms that cause forgetting? How is competition between memories signaled and resolved in the brain during retrieval? How do we reduce interference between memories during encoding? Addressing these questions involves understanding the interactions and relative contributions of fronto-parietal cortex and medial temporal lobe structures.


Transforming the Concept of Memory Reactivation.

Trends Neurosci. 2020 Oct 08;:

Authors: Favila SE, Lee H, Kuhl BA

Reactivation refers to the phenomenon wherein patterns of neural activity expressed during perceptual experience are re-expressed at a later time, a putative neural marker of memory. Reactivation of perceptual content has been observed across many cortical areas and correlates with objective and subjective expressions of memory in humans. However, because reactivation emphasizes similarities between perceptual and memory-based representations, it obscures differences in how perceptual events and memories are represented. Here, we highlight recent evidence of systematic differences in how (and where) perceptual events and memories are represented in the brain. We argue that neural representations of memories are best thought of as spatially transformed versions of perceptual representations. We consider why spatial transformations occur and identify critical questions for future research.

When the Memory System Gets Ahead of Itself.

Trends Cogn Sci. 2020 Oct 06;:

Authors: Long NM, Kuhl BA

Humans are adept at learning and exploiting statistical regularities to predict future events from current experience. A recent paper by Sherman and Turk-Browne demonstrates that statistical regularities bias the hippocampus toward representing future states over current experience and reduce the degree to which current experience is encoded into memory.
