Representation of geometric borders in the entorhinal cortex

T Solstad, CN Boccara, E Kropff, MB Moser, EI Moser - Science, 2008 - science.org
We report the existence of an entorhinal cell type that fires when an animal is close to the
borders of the proximal environment. The orientation-specific edge-apposing activity of these “…

Grid cells in pre-and parasubiculum

CN Boccara, F Sargolini, VH Thoresen, T Solstad… - Nature …, 2010 - nature.com
Allocentric space is mapped by a widespread brain circuit of functionally specialized cell types
located in interconnected subregions of the hippocampal-parahippocampal cortices. Little …

The entorhinal cognitive map is attracted to goals

CN Boccara, M Nardin, F Stella, J O'Neill, J Csicsvari - Science, 2019 - science.org
Grid cells with their rigid hexagonal firing fields are thought to provide an invariant metric to
the hippocampal cognitive map, yet environmental geometrical features have recently been …

Superficial layers of the medial entorhinal cortex replay independently of the hippocampus

J O'Neill, CN Boccara, F Stella, P Schönenberger… - Science, 2017 - science.org
The hippocampus is thought to initiate systems-wide mnemonic processes through the
reactivation of previously acquired spatial and episodic memory traces, which can recruit the …

A three‐plane architectonic atlas of the rat hippocampal region

CN Boccara, LJ Kjonigsen, IM Hammer… - …, 2015 - Wiley Online Library
The hippocampal region, comprising the hippocampal formation and the parahippocampal
region, has been one of the most intensively studied parts of the brain for decades. Better …

[PDF][PDF] Dissociation between postrhinal cortex and downstream parahippocampal regions in the representation of egocentric boundaries

X Gofman, G Tocker, S Weiss, CN Boccara, L Lu… - Current Biology, 2019 - cell.com
Navigation requires the integration of many sensory inputs to form a multi-modal cognitive
map of the environment, which is believed to be implemented in the hippocampal region by …

[HTML][HTML] Angular and linear speed cells in the parahippocampal circuits

D Spalla, A Treves, CN Boccara - Nature communications, 2022 - nature.com
An essential role of the hippocampal region is to integrate information to compute and
update representations. How this transpires is highly debated. Many theories hinge on the …

[HTML][HTML] Activity dependent feedback inhibition may maintain head direction signals in mouse presubiculum

…, F Stella, I Cohen, B Mathon, CN Boccara… - Nature …, 2017 - nature.com
Orientation in space is represented in specialized brain circuits. Persistent head direction
signals are transmitted from anterior thalamus to the presubiculum, but the identity of the …

Experimental observation of localized optical excitations in random metal-dielectric films

S Grésillon, L Aigouy, AC Boccara, JC Rivoal… - Physical Review Letters, 1999 - APS
… For a macroscopically homogeneous random film, the spatial locations of cn do not correlate
with the value of Ln, so that we can independently average the numerator in Eq. (1). Taking …

[HTML][HTML] Pkd2l1 is required for mechanoception in cerebrospinal fluid-contacting neurons and maintenance of spine curvature

…, S Kurisu, JR McDearmid, PL Bardet, C Boccara… - Nature …, 2018 - nature.com
… To investigate whether CSF-cN activity relied on cilia motility, we monitored CSF-cN calcium
activity in cfap298 homozygous mutants. CSF-cN activity in paralyzed cfap298 mutants at …
