Generalization of cognitive maps across space and time

Autor: Katherine R Sherrill, Robert J Molitor, Ata B Karagoz, Manasa Atyam, Michael L Mack, Alison R Preston

Publikováno v: Cerebral Cortex.

Prominent theories posit that associative memory structures, known as cognitive maps, support flexible generalization of knowledge across cognitive domains. Here, we evince a representational account of cognitive map flexibility by quantifying how sp

Memory Reactivation during Learning Simultaneously Promotes Dentate Gyrus/CA(2,3) Pattern Differentiation and CA(1) Memory Integration

Autor: Alison R. Preston, Katherine R. Sherrill, Alexandra A. Miller, Robert J. Molitor, Neal W Morton

Publikováno v: J Neurosci

Events that overlap with previous experience may trigger reactivation of existing memories. However, such reactivation may have different representational consequences within the hippocampal circuit. Computational theories of hippocampal function sug

Memory integration constructs maps of space, time, and concepts

Autor: Neal W Morton, Katherine R. Sherrill, Alison R. Preston

Publikováno v: Current Opinion in Behavioral Sciences. 17:161-168

Recent evidence demonstrates that new events are learned in the context of their relationships to existing memories. Within the hippocampus and medial prefrontal cortex, related memories are represented by integrated codes that connect events experie

There and Back Again: Hippocampus and Retrosplenial Cortex Track Homing Distance during Human Path Integration

Autor: Michael E. Hasselmo, Katherine R. Sherrill, Chantal E. Stern, Elizabeth R. Chrastil

Publikováno v: The Journal of Neuroscience. 35:15442-15452

Path integration, the updating of position and orientation during movement, often involves tracking a home location. Here, we examine processes that could contribute to successful location tracking in humans. In particular, we investigate a homing ve

Structural Differences in Hippocampal and Entorhinal Gray Matter Volume Support Individual Differences in First Person Navigational Ability

Autor: Michael E. Hasselmo, Katherine R. Sherrill, Irem Aselcioglu, Elizabeth R. Chrastil, Chantal E. Stern

Publikováno v: Neuroscience. 380

The ability to update position and orientation to reach a goal is crucial to spatial navigation and individuals vary considerably in this ability. The current structural MRI study used voxel-based morphometry (VBM) analysis to relate individual diffe

Path integration, the constant updating of the navigator's knowledge of position and orientation during movement, requires both visuospatial knowledge and memory. This study aimed to develop a systems-level understanding of human path integration by

The hippocampus is functionally connected to the striatum and orbitofrontal cortex during context dependent decision making

Autor: Katherine R. Sherrill, Robert S. Ross, Chantal E. Stern

Publikováno v: Brain Research. 1423:53-66

Many of our everyday actions are only appropriate in certain situations and selecting the appropriate behavior requires that we use current context and previous experience to guide our decisions. The current study examined hippocampal functional conn

Functional connections between optic flow areas and navigationally responsive brain regions during goal-directed navigation

Autor: Elizabeth R. Chrastil, Katherine R. Sherrill, Uğur M. Erdem, Robert S. Ross, Chantal E. Stern, Michael E. Hasselmo

Publikováno v: Neuroimage

Recent computational models suggest that visual input from optic flow provides information about egocentric (navigator-centered) motion and influences firing patterns in spatially tuned cells during navigation. Computationally, self-motion cues can b

Individual Differences in Human Path Integration Abilities Correlate with Gray Matter Volume in Retrosplenial Cortex, Hippocampus, and Medial Prefrontal Cortex

Autor: Michael E. Hasselmo, Irem Aselcioglu, Katherine R. Sherrill, Chantal E. Stern, Elizabeth R. Chrastil

Publikováno v: eNeuro

Humans differ in their individual navigational abilities. These individual differences may exist in part because successful navigation relies on several disparate abilities, which rely on different brain structures. One such navigational capability i

Hippocampus and Retrosplenial Cortex Combine Path Integration Signals for Successful Navigation

Autor: Chantal E. Stern, Michael E. Hasselmo, Thackery I. Brown, Katherine R. Sherrill, Uğur M. Erdem, Robert S. Ross

The current study used fMRI in humans to examine goal-directed navigation in an open field environment. We designed a task that required participants to encode survey-level spatial information and subsequently navigate to a goal location in either fi
