Hippocampus and retrosplenial cortex combine path integration signals for successful navigation

KR Sherrill, UM Erdem, RS Ross, TI Brown… - Journal of …, 2013 - Soc Neuroscience
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 …

There and back again: hippocampus and retrosplenial cortex track homing distance during human path integration

ER Chrastil, KR Sherrill, ME Hasselmo… - Journal of …, 2015 - Soc Neuroscience
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 …

Memory reactivation during learning simultaneously promotes dentate gyrus/CA2, 3 pattern differentiation and CA1 memory integration

RJ Molitor, KR Sherrill, NW Morton… - Journal of …, 2021 - Soc Neuroscience
Events that overlap with previous experience may trigger reactivation of existing memories.
However, such reactivation may have different representational consequences within the …

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

KR Sherrill, ER Chrastil, RS Ross, UM Erdem… - Neuroimage, 2015 - Elsevier
Recent computational models suggest that visual input from optic flow provides information
about egocentric (navigator-centered) motion and influences firing patterns in spatially tuned …

Individual differences in human path integration abilities correlate with gray matter volume in retrosplenial cortex, hippocampus, and medial prefrontal cortex

ER Chrastil, KR Sherrill, I Aselcioglu, ME Hasselmo… - Eneuro, 2017 - eneuro.org
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 …

Generalization of cognitive maps across space and time

KR Sherrill, RJ Molitor, AB Karagoz, M Atyam… - Cerebral …, 2023 - academic.oup.com
Prominent theories posit that associative memory structures, known as cognitive maps,
support flexible generalization of knowledge across cognitive domains. Here, we evince a …

Which way and how far? Tracking of translation and rotation information for human path integration

ER Chrastil, KR Sherrill, ME Hasselmo… - Human Brain …, 2016 - Wiley Online Library
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 …

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

RS Ross, KR Sherrill, CE Stern - Brain research, 2011 - Elsevier
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 …

Structural differences in hippocampal and entorhinal gray matter volume support individual differences in first person navigational ability

KR Sherrill, ER Chrastil, I Aselcioglu, ME Hasselmo… - Neuroscience, 2018 - Elsevier
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-…
