An anatomical study of the efferent connections of the thalamic reticular nucleus
Experimental Brain Research, 1971A neuro-anatomical investigation into the thalamic reticular nucleus and its connections was made in the albino rat, using the method of retrograde degeneration and the Nauta-Gygax method. The results correspond to the description given by Scheibel and Scheibel and indicate connections of the neurons of the reticular which the principal thalamic nuclei

Behaviorally Modulated Filter Model for the Thalamic Reticular Nucleus
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Incoming sensory information is first processed in the thalamocortical network. Previous studies showed that the responses generated in the nuclei of this network are behaviorally modulated, suggesting that the processing of the somatosensory information could be state dependent.

Thalamocortical dysrhythmia and the thalamic reticular nucleus in behaving rats
Clinical Neurophysiology, 2002The aim of this study was to investigate the effects of bilateral chemical lesion of the rostral pole of the thalamic reticular nucleus on EEG activities in freely moving rats applying quantitative analysis and brain mapping of power spectra distribution.Ketamine-sedated Sprague-Dawley rats were implanted to monitor behavioral states with ...

The thalamic reticular nucleus: structure, function and concept
Brain Research Reviews, 2004On the basis of theoretical, anatomical, psychological and physiological considerations, Francis Crick (1984) proposed that, during selective attention, the thalamic reticular nucleus (TRN) controls the internal attentional searchlight that simultaneously highlights all the neural circuits called on by the object of attention.

Examining Cholinergic Synaptic Signaling in the Thalamic Reticular Nucleus
Cold Spring Harbor Protocols, 2017This protocol describes how to obtain monosynaptic cholinergic responses in neurons of the thalamic reticular nucleus (TRN) by making use of extracellular stimulation techniques. These methods are easy to implement and allow for the study of various forms of cholinergic synaptic plasticity and modulation.

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 ...
