mGluR-mediated calcium signalling in the thalamic reticular nucleus
Cell Calcium, 2016The thalamic reticular nucleus (TRN) plays a major role in modulating the transfer of information from the thalamus to the cortex. GABAergic inhibition via the TRN is differentially regulated by metabotropic glutamate receptors (mGluRs) and the effect of mGluRs on the membrane potential, on ion channels, and on the plasticity of electrical coupling of ...

Evolution of neuronal density in the ageing thalamic reticular nucleus
Mechanisms of Ageing and Development, 1995In this paper we present an analysis of the visual sector of the Thalamic Reticular Nucleus (TRN) from 3, 6, 18, 24 and 30 month old Wistar rats using stereological methods. The volume density (Vv), the number of neurones per surface unit (Na) and the neurone numerical density (Nv) showed a progressive decrease between the 3rd and the 24th months as ...

Connections of the thalamic reticular nucleus with the contralateral thalamus in the rat
Neuroscience Letters, 1992The occurrence of thalamic projections to the contralateral side of the thalamus, and the origin of these projections from the thalamic reticular nucleus, were demonstrated with fluorescent retrograde tracing. After a relatively large tracer injection in the anterior third of the thalamus (involving the reticular, anterior, intralaminar and ...

Cytoarchitectonic heterogeneities in the thalamic reticular nucleus of cats and ferrets
Journal of Comparative Neurology, 1992AbstractThe thalamic reticular nucleus has been classically defined as a group of cells surrounding most of the rostral and lateral surfaces of the dorsal thalamus, lateral to the fibres of the external medullary lamina and medial to those of the internal capsule. With the use of Nissl staining and antibodies to γ‐aminobutyric acid (GABA), somatostatin,

The deafferented reticular thalamic nucleus generates spindle rhythmicity
Journal of Neurophysiology, 1987The hypothesis that nucleus reticularis thalami (RE) is the generator of spindle rhythmicity during electroencephalogram (EEG) synchronization was tested in acutely prepared cats. Unit discharges and focal waves were extracellularly recorded in the rostral pole of RE nucleus, which was completely disconnected by transections from all other thalamic ...

Imaging The Thalamic Reticular Nucleus at 7T
ISMRM Annual MeetingThe Thalamic Reticular Nucleus is a micro-structure surrounding the dorsal edge of the thalamus that is of fundamental significance to understanding many neurological disorders in the brain. Here we present methods to visualise the TRN using various imaging modalities to explore different sources of contrast at the edge of the thalamus.

[Structural organization of the reticular thalamic nucleus].
Morfologiia (Saint Petersburg, Russia), 2006This review presents an analysis of current data on the structural organization of the reticular thalamic nucleus (RTN). In contains a detailed discussion on topography, cytoarchitecture, neuronal organization and neurogenesis in this nucleus.

Intrathalamic sensory connections mediated by the thalamic reticular nucleus
Cellular and Molecular Life Sciences (CMLS), 1999The thalamus and cerebral cortex are linked together to form a vast network of interconnections. Different modes of interactions among the cells in this network underlie different states of consciousness, such as wakefulness and sleep. Interposed between the dorsal thalamus and cortex are the GABAergic neurons of the thalamic reticular nucleus (TRN ...

Organization in the somatosensory sector of the cat's thalamic reticular nucleus
The Journal of Comparative Neurology, 1996This study describes the organization of cells in the thalamic reticular nucleus (TRN) that project to the somatosensory part of the dorsal thalamus in the cat. Injections of wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP) and fluorescent dyes were made into the ventrobasal complex (VB) and the medial division of the posterior ...

Organization in the auditory sector of the cat's thalamic reticular nucleus
The Journal of Comparative Neurology, 1998This study describes the organization of cells in the thalamic reticular nucleus (TRN) that project to the auditory part of the cat's dorsal thalamus. Injections of wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP) and fluorescent dyes were made into the medial geniculate complex (MG).
