The overdispersion in activity of place cells
Neurocomputing, 2001Abstract The spontaneous discharge of place cells reflects the position of an animal in its environment. The firing rate is high inside a part of it, called the firing field, and low outside. It has been found experimentally that while the activity of place cells is highly reliable in position, it does not retain the same reliability in time.

Place cells in the ventral hippocampus of rats
NeuroReport, 1994Many cells recorded from the dorsal hippocampus of freely moving rats are intensely active only when the rat's head is in a particular part of its environment. For this reason, such units are called 'place cells'. We have investigated whether place cells are also found in the ventral hippocampus.

Imaging Despite considerable progress in recent years, pathological analysis of tissues and organs often still relies on old-fashioned microscopic techniques. Similarly, genomic and transcriptomic analysis is commonly applied to bulk tissue samples. To address the limitations of these approaches, Zhao et al. and van Ineveld et al.

Challenges for Place and Grid Cell Models
2021This chapter gives a short overview of computational models dealing with two fundamental building blocks in spatial cognition: grid and place cells, and of the open issues such models may help address.

Is the place cell a “supple” engram?
Hippocampus, 2015ABSTRACTThis short note, which honors Nobelists O'Keefe and the Mosers, asks how the patterning of inputs to a single place cell regulates its firing. Because the combination of inputs to a single CA1 place cell is very large, the generally accepted view is rejected that inputs to a place cell are relatively restricted, near identical repetition upon ...

Overview of asthma; the place of the T cell
Current Opinion in Pharmacology, 2010Asthma is an inflammatory disease which is associated with activated T cells in the airway wall. The contribution of the T lymphocyte to inflammation in asthma has been extensively studied through descriptions of T cell subsets in the airway wall of asthmatic patients and from animal and cellular models.

Introduction to the Special Issue on Place Cells
Hippocampus, 1999In 1971, John O’Keefe and Jonathan Dostrovsky discovered place cells, and the hippocampal world has not been the same since. In the nearly 30 years since that discovery, hundreds of studies have been published, and thousands of words have been written, yet full understanding of the function of these cells and the role they collectively play in the ...

Plasticity of the Hippocampal Place Cell Representation
Reviews in the Neurosciences, 2004The role of the hippocampus in the representation of 'place' has been attributed to the place cells, whose spatially localised firing suggests their participation in forming a cognitive map of the environment. That this map is necessary for spatial memory formation is indicated by the propensity of almost all navigational tasks to be disrupted by ...

STKE Vascular proliferative diseases, such as atherosclerosis and coronary restenosis, are characterized by dedifferentiation, abnormal proliferation, and migration of vascular smooth muscle cells, a pathophysiological reaction to injury that has been interpreted as a response to cytokines released by inflammatory cells.

Stochastic model of the place cell discharge
1999The firing activity of place cells of the hippocampus reflects movements of an animal in its experimental area. This well known fact was recently reinvestigated (Fenton and Muller, 1998) and it was found that while the activity was highly reliable in space, it did not retain the same reliability in time. The number of spikes discharged during different
