The Thalamic Reticular Nucleus

2023
Abstract The thalamic reticular nucleus (TRN), an entirely GABAergic shell-shaped structure, is reciprocally connected with the thalamus, where it circulates—via the thalamocortical and corticothalamic axons—temporal and multimodal information.

The Thalamic Reticular Nucleus: More Than a Sensory Nucleus?

The Neuroscientist, 2002
Sensory information is routed to the cortex via the thalamus, but despite this sensory bombardment, animals must attend selectively to stimuli that signal danger or opportunity. Sensory input must be filtered, allowing only behaviorally relevant information to capture limited attentional resources.

Thalamic reticular nucleus in the thalamocortical loop

Neuroscience Research, 2020
Dynamic binding of different brain areas is critical for various cognitive functions. The thalamic reticular nucleus (TRN) is a GABAergic nucleus that constrains information flow through thalamocortical loop by providing inhibitory innervation to the thalamus.

Organization of the Visual Reticular Thalamic Nucleus of the Rat

European Journal of Neuroscience, 1996
AbstractThe 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, 1998
To 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, 1984
Mapping 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, 1988
AbstractThis 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 ...

Thalamic nucleus submedius receives GABAergic projection from thalamic reticular nucleus in the rat

Neuroscience, 2005
GABAergic projection from thalamic reticular nucleus to thalamic nucleus submedius in the medial thalamus of the rat was studied by using immunohistochemistry for GABA, retrograde labeling with Fluoro-Gold combined with immunohistochemistry for GABA, and anterograde labeling with biotinylated dextranamine.

Neuronal subpopulations in a reptilian thalamic reticular nucleus

NeuroReport, 1993
In 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, 1983
In 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
