Propagation of Hippocampal Ripples to the Neocortex by Way of a Subiculum-Retrosplenial Pathway [article]

Noam Nitzan, Sam McKenzie, Prateep Beed, Daniel Fine English, Silvia Oldani, John Jan Tukker, György Buzsáki, Dietmar Schmitz
2020 bioRxiv   pre-print
Due to its anatomical positioning, the granular retrosplenial cortex (gRSC) may be a bridge for this hippocampo-cortical dialogue.  ...  Using silicon probe recordings in awake, head-fixed mice, we show the existence of SPW-R analogues in gRSC and demonstrate their coupling to hippocampal SPW-Rs. gRSC neurons reliably distinguished different  ...  The retrosplenial cortex: intrinsic connectivity and connections with the (para)hippocampal region in the rat.

Evidence for an anterior–posterior differentiation in the human hippocampal formation revealed by meta-analytic parcellation of fMRI coordinate maps: Focus on the subiculum

Henry W. Chase, Mareike Clos, Sofia Dibble, Peter Fox, Anthony A. Grace, Mary L. Phillips, Simon B. Eickhoff
2015 NeuroImage  
Functional connectivity assessed both by meta-analytic and resting fMRI approaches revealed that more 33 anterior regions were more strongly connected to the default mode network, and more posterior regions  ...  across the hippocampal formation.  ...  It is likely that interactions between the RC 851 and hippocampal formation play an important role in spatial memory 852 (Albasser et al., 2007).  ...

Visual cues determine hippocampal directional selectivity [article]

Lavanya Acharya, Zahra M. Aghajan, Cliff Vuong, Jason Moore, Mayank Mehta
2015 bioRxiv   pre-print
Several additional experiments revealed that changes in the angular information contained in the visual cues induced corresponding changes in hippocampal head-directional modulation.  ...  However, hippocampal neurons are thought to show no angular modulation during two-dimensional random foraging despite the presence of vestibular and visual cues.  ...  Popeney for help with behavioral training, J.

Functional architecture of the medial entorhinal cortex [article]

Saikat Ray, Humboldt-Universität Zu Berlin, Humboldt-Universität Zu Berlin
2017
The medial entorhinal cortex (MEC) is an important hub in the memory circuit in the brain. This thesis comprises of a group of studies which explores the architecture and microcircuits of the MEC.  ...  An investigation of the ontogeny of the MEC in rats revealed that the periodic structure of the calbindin-patches and scattered layout of reelin-positive stellate cells was present around birth.  ...  We are thankful to Francesca Sargolini, May-Britt and Edvard Moser and the other authors , who generously provided access to grid cell data, which were helpful in assembling an earlier version of this  ...

Structural basis of large-scale functional connectivity in the mouse

Joanes Grandjean, Valerio Zerbi, Joshua Henk Balsters, Nicole Wenderoth, Markus Rudin
2017
Here, we compared FC derived from rs-fMRI in female mice with the underlying monosynaptic structural connectome as provided by the Allen Brain Connectivity Atlas.  ...  Given the recent rise in preclinical neuroimaging of mouse models, it is an important question whether the mouse functional connectome conforms to the underlying SC.  ...  Specifically, these areas of good correspondence reflect the connections between the anteroventral nuclei of the TH with retrosplenial cortex (Fig. 4d , purple) and between the ventral posteromedial nuclei  ...

Gerald Moore, Stephen Brickley, Simon Schultz
2021
Second, STP tomography and magnetic resonance imaging (MRI) were explored for correlating age-related cognitive changes with anatomical connectivity.  ...  To this end, the following pipelines were created and validated; stitching of tile image data, registration of data with common coordinate framework, and a deep learning cell detection algorithm that was  ...  of contrasting landmarks in the hippocampal formation.  ...
