What is thalamic reticular nucleus?

Background: The thalamic reticular nucleus (TRN) is a shell-shaped gamma amino butyric acid (GABA)ergic nucleus, which is uniquely placed between the thalamus and the cortex, because it receives excitatory afferents from both cortical and thalamic neurons and sends inhibitory projections to all nuclei of the dorsal …

Where is reticular nucleus located?

brainstem
The reticular formation nuclei are found deep within the brainstem, along its length. It is easier to appreciate the approximate location of these nuclei if they are superimposed on a posterior view of the brainstem with the cerebellum removed. Topographically, the nuclei can be divided into three groups.

What is the Centromedian nucleus of the thalamus?

The centromedian (CM) nucleus is an intralaminar thalamic nucleus that is considered as a potentially effective target of deep brain stimulation (DBS) and ablative surgeries for the treatment of multiple neurological and psychiatric disorders.

What’s reticular mean?

adjective. having the form of a net; netlike. intricate or entangled. Anatomy. of or relating to a reticulum.

What is the main function of the reticular formation?

The brainstem reticular formation (RF) represents the archaic core of those pathways connecting the spinal cord and the encephalon. It subserves autonomic, motor, sensory, behavioral, cognitive, and mood-related functions.

What is anterior thalamic nuclei?

Abstract. The anterior thalamic nuclei are a vital node within hippocampal-diencephalic-cingulate circuits that support spatial learning and memory. Reflecting this interconnectivity, the overwhelming focus of research into the cognitive functions of the anterior thalamic nuclei has been spatial processing.

What does the pulvinar nucleus do?

The pulvinar is the largest nucleus of the thalamus and has strong connectivity with the visual cortex. The pulvinar is a prototypic association nucleus that participates in reciprocal cortico-cortical interactions and promotes synchronized oscillatory activity in functionally related areas of the cortex.

What are the functions of the brainstem thalamus reticular formation and cerebellum?

Reticular Formation- Is made of nerve cells running from spinal cord to brain stem and then to thalamus. This part of the brain is involved in eating, sleeping and when you become aroused. It filters stimuli and passes on important signals. Cerebellum- controls coordination of muscular activity.

What is the function of the reticular formation?

What happens when thalamus is damaged?

While thalamus damage primarily causes sensory problems, it can also lead to behavioral and cognitive changes. For example, many patients with a thalamus injury have incorrect speech patterns and can struggle to find the right words. Others display apathy and memory problems.
