Distinct patterns of dentate gyrus cell activation distinguish physiologic from aberrant stimuli.

open access: yesPLoS ONE, 2020
Under physiologic conditions, the dentate gyrus (DG) exhibits exceptionally low levels of activity compared to other brain regions. A sparse activation pattern is observed even when the DG is engaged to process new information; for example, only ~1-3% of

Analysis of granule cell generation system by lie symmetry method

open access: yesCumhuriyet Science Journal, 2020
In this paper, we study main headlines of brain development which is a major problem in neurobiology in present. Our aim here is to find the analytical solution of the equation that belongs to the brain development system. For this solution, the exchange

Experimental simulation of the ancient production of gold granules

open access: yesHeritage Science
Granulation is an ancient and sophisticated decorative technique. The production of granules is a crucial part of this process but has rarely been studied. The present study employed three techniques—pouring method, heating method, and crucible method—to

Associative plasticity of granule cell inputs to cerebellar Purkinje cells

open access: yeseLife
Granule cells of the cerebellum make up to 175,000 excitatory synapses on a single Purkinje cell, encoding the wide variety of information from the mossy fibre inputs into the cerebellar cortex. The granule cell axon is made of an ascending portion and a

PTEN deletion from adult-generated dentate granule cells disrupts granule cell mossy fiber axon structure

open access: yesNeurobiology of Disease, 2015
Dysregulation of the mTOR-signaling pathway is implicated in the development of temporal lobe epilepsy. In mice, deletion of PTEN from hippocampal dentate granule cells leads to mTOR hyperactivation and promotes the rapid onset of spontaneous seizures ...

An Improved Axiomatic Definition of Information Granulation

open access: yesFundamenta Informaticae, 2012
To capture the uncertainty of information or knowledge in information systems, various information granulations, also known as knowledge granulations, have been proposed. Recently, several axiomatic definitions of information granulation have been introduced. In this paper, we try to improve these axiomatic definitions and give a universal construction

Eosinophil granule proteins and bronchial asthma

open access: yesAllergology International, 1996
For over 100 years, the association of eosinophils with bronchial asthma has been known. Over the past 20 years, the proteins comprising the eosinophil granule have been isolated and characterized.

Information granulation and rough set approximation [PDF]

open access: yesInternational Journal of Intelligent Systems, 2000
Summary: Information granulation and concept approximation are some of the fundamental issues of granular computing. Granulation of a universe involves grouping of similar elements into granules to form coarse-grained views of the universe. Approximation of concepts, represented by subsets of the universe, deals with the descriptions of concepts using ...
