Organization of the Visual Reticular Thalamic Nucleus of the Rat
European Journal of Neuroscience, 1996AbstractThe visual sector of the reticular thalamic nucleus has come under some intense scrutiny over recent years, principally because of the key role that the nucleus plays in the processing of visual information. Despite this scrutiny, we know very little of how the connections between the reticular nucleus and the different areas of visual cortex ...

Patterns of brainstem projection to the thalamic reticular nucleus
The Journal of Comparative Neurology, 1998To understand better how the brainstem may influence thalamocortical activity, we have examined the projection patterns of different brainstem nuclei to the thalamic reticular nucleus. Iontophoretic injections of biotinylated dextran were made into various nuclei of the brainstem (superior colliculus, periaqueductal grey matter, parabrachial nucleus ...

Somatotopic organization in the rat thalamic reticular nucleus
Brain Research, 1984Mapping experiments were carried out to establish the somatotopic organization of the somatosensory part of the thalamic reticular nucleus (TR) of the rat. Different parts of the body were found to project somatotopically onto the S-TR. The rostral-to-caudal and the dorsal-to-ventral axes in the body parts were transformed into the ventral-to-dorsal ...

Synaptic organization of the thalamic reticular nucleus
Journal of Electron Microscopy Technique, 1988AbstractThis study describes the synaptic organization of the thalamic reticular nucleus (TRN) in the rat, cat, and monkey using electron microscopy combined with immunocytochemistry, degeneration, or horseradish peroxidase (HRP) tracing methods. Three morphological types of terminals are described in the TRN of the rat: a small terminal with densely ...

Neuronal subpopulations in a reptilian thalamic reticular nucleus
NeuroReport, 1993In reptiles, Caiman crocodilus, some neurons in the thalamic reticular nucleus are immunoreactive for parvalbumin. Utilizing double-labeling experiments with fluorescent tracers and indirect fluorescence immunocytochemistry, some of these parvalbumin immunoreactive neurons were found to project to the dorsal thalamus.

Auditory neurons in the rat thalamic reticular nucleus
Experimental Brain Research, 1983In the thalamic reticular nucleus (TR) of the rat a cluster of neurons has been located which receives auditory inputs and acts as a source of inhibition for relay neurons of the medial geniculate nucleus (MG). These TR neurons (auditory thalamic reticular neurons; A-TR neurons) showed a repetitive burst of grouped discharge upon electrical stimulation

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.
