Recurrent inhibitory circuitry as a mechanism for grid formation

…, A Witoelar, SJ Zhang, K Zheng, J Ye, B Dunn… - Nature …, 2013 - nature.com
Grid cells in layer II of the medial entorhinal cortex form a principal component of the
mammalian neural representation of space. The firing pattern of a single grid cell has been …

Grid cells require excitatory drive from the hippocampus

T Bonnevie, B Dunn, M Fyhn, T Hafting… - Nature …, 2013 - nature.com
To determine how hippocampal backprojections influence spatially periodic firing in grid
cells, we recorded neural activity in the medial entorhinal cortex (MEC) of rats after temporary …

[PDF][PDF] A novel mechanism for the grid-to-place cell transformation revealed by transgenic depolarization of medial entorhinal cortex layer II

…, CM Lykken, D Avesar, A Weible, J Dickinson, B Dunn… - Neuron, 2017 - cell.com
The spatial receptive fields of neurons in medial entorhinal cortex layer II (MECII) and in the
hippocampus suggest general and environment-specific maps of space, respectively. …

Efficient cortical coding of 3D posture in freely behaving rats

B Mimica, BA Dunn, T Tombaz, VS Bojja, JR Whitlock - Science, 2018 - science.org
Animals constantly update their body posture to meet behavioral demands, but little is known
about the neural signals on which this depends. We therefore tracked freely foraging rats in …

[HTML][HTML] Toroidal topology of population activity in grid cells

…, M Pachitariu, Y Burak, NA Baas, BA Dunn… - Nature, 2022 - nature.com
The medial entorhinal cortex is part of a neural system for mapping the position of an
individual within a physical environment 1 . Grid cells, a key component of this system, fire in a …

[HTML][HTML] Correlations and functional connections in a population of grid cells

B Dunn, M Mørreaunet, Y Roudi - PLoS computational biology, 2015 - journals.plos.org
We study the statistics of spike trains of simultaneously recorded grid cells in freely behaving
rats. We evaluate pairwise correlations between these cells and, using a maximum entropy …

[HTML][HTML] Behavioral decomposition reveals rich encoding structure employed across neocortex in rats

…, T Tombaz, C Battistin, JG Fuglstad, BA Dunn… - Nature …, 2023 - nature.com
The cortical population code is pervaded by activity patterns evoked by movement, but it
remains largely unknown how such signals relate to natural behavior or how they might support …

Learning and inference in a nonequilibrium Ising model with hidden nodes

B Dunn, Y Roudi - Physical Review E, 2013 - APS
We study inference and reconstruction of couplings in a partially observed kinetic Ising
model. With hidden spins, calculating the likelihood of a sequence of observed spin …

Lipomas of the thymus gland: with an illustrative case report

BH Dunn, G Frkovich - The American Journal of Pathology, 1956 - ncbi.nlm.nih.gov
Although reports on malignant tumors of the thymus gland appear fairly frequently, those on
benign tumors of thymic origin are relatively rare. Perhaps the most common benign …

Score-based generative classifiers

…, L Schott, Y Song, BA Dunn… - … 2021 Workshop on …, 2021 - openreview.net
The tremendous success of generative models in recent years raises the question of whether
they can also be used to perform classification. Generative models have been used as …
