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
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
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
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
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
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
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
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
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 …
